2JZ swap *BUILD THREAD*

[crazysupra2JZ]

well, i had a slight change of plans in my other build 'Rita's Big Build'

I've decided to swap in a stock twin turbo 2JZ. I love the MKIII look but i want the MKIV power. so today i painted my engine bay black cause someday i'm gonna paint the car black. so i should have the engine by may or june at the latest. and then i need to look for a 89+ cross member. but i don't know why i can't just remove the 7M engine mounts and weld in 2JZ mounts. i'm still in the process of researching all i need to do but for now i need to get my hands on a 2JZ... i'm also just gonna keep the 2JZ stock for now. i figure 320 hp is good enough for now. that's 120 more than i currently have

i'm gonna replace the head gasket, ARP studs, and other things i can replace that's cheap...

progress so far
1JZ bellhousing
1Jz flywheel
Spec stage 3 6 puck clutch kit
BIC motor mounts
2JZ-GTE
ECU
Engine harness
SAFC 2
2JZ waterpump
lightweight pulley set

depending on how the R154 feels i might keep it and get a jawsgear driveshaft. otherwise i'm gonna be swapping in a V160, eventually.

[Brewster]

why would you replace the hg on a 2j?

[SD2JZA70]

seriously. the money would be better spent elsewhere. spend your headgasket and stud money on BPU stuff.

[crazysupra2JZ]

why would you replace the hg on a 2j?

i could do a compression test on it first i guess. but it's just for piece of mind...i guess i'm just used to the 7M and it's HG problems... never had any experience with 2jz's

[SD2JZA70]

2J's dont have the headgasket issues the 7m does. they have a MHG from the factory

[OneJoeZee]

the stock HG is metal. don't worry about replacing it.

edit: damn you darian. lol.

[Brewster]

lol dude, you don't need to touch the hg.

edit: damn you both!

[crazysupra2JZ]

well thanks for the info... just saved $200

[thechori]

nope, you saved more than that

[kwnate]

I've decided to swap in a stock twin turbo 2JZ. I love the MKIII look but i want the MKIV power. have

Cause we all know that the stock power of a 2j is unobtainable with a 7m :icon_razz

Good luck with your swap!

i know the 7M is capable of making a lot of power. but the 7m can't rev to 9000 rpm. i'm still keeping my 7M, i'm gonna rebuild it eventually.

thanks though, the wiring i know is going to be a nightmare

[crazysupra2JZ]

well... i just ordered a 2JZ-GTE with the engine harness and ecu and i bought the motor mounts from BIC and 1JZ flywheel and stage 4 7M/1JZ clutch kit form 935 Motorsports... hopefully everything should be here with 2 weeks....post pics then...now all i needs is a 1JZ bellhousing..time to go to junkyards in Atlanta

[starscream5000]

You won't keep it stock "for now" ;), at least put a full turbo back on it along with hard pipes and FMIC...

[crazysupra2JZ]

haha...well you see, i no longer have any money to modd it. i'm gonna go BPU for now then when i have some money saved up i'll take it out and upgrade it. HKS Dragger II is what i REALLY want and i have a 12x24x4 intercooler already and i'm gonna put in either 3" or 2.5" intercooler pipes with a HKS SSQV

[starscream5000]

If your power goals are ~550 HP and under, 2.5" piping will suffice for most. Getting 3" hardpipes will lower the velocity of the air going through it too low and you will be getting no where fast ;). Critical velocity is where you want to be at with the tubing (barely under CV actually).

[boostadikt]

people don't give the 7m enough credit..... :nono: the real reason you see 2jz's making mega HP is because in general the people with mkiv's building them Have the big bucks and dont flinch when they need to spend 3,000$ on a turbo. if you put 60k in a mkiii with a 7m you would get the same results..... Just my opinion

but the engine bay looks great! and good luck with your swap:icon_bigg

well don't get me wrong now. i still believe the 7M is a great motor, but you just can't deny newer technology. i for one don't want to be changing the head gasket on my 7M every year.

[boostadikt]

actually that is just my argument... if you put new technology into a 7m it is just as good, forged pistons, rods ect, and if you put a metal headgasket and studs in a 7m i dont see how you could ever have a hg problem again unless something was done wrong. and also the 2jz is pretty old technology as well, the motor is now completely ceased production even the GE, in order to make the 2jz the magnificent motor it is, it needs newer technology as well.

No doubt the 2jz is a far better motor from the get go but for potential, i dont think so... with the proper money invested the 7m can be just as great.

im not trying to bring you down at all, i have thought about 1j and 2j swaps many times but i love seeing a well built 7m, and you will have more power potential from a factory 2j than a 7m but again if your goals ever reach Really High #s they are on the same platform

[boostadikt]

I really am just stating my opinion, and i do wish you all the best luck with your swap and that it will be everything you want it to be

but it looks like it is time to change your name.:)

Sorry bro - 2J>7m

You have to invest a lot of money in a 7M to make it as capable as a stock 2JZ. My guess is that youve never taken both the motors apart and looked at them.

[boostadikt]

wow im glad that you read what i typed..... i said 2j's are better stock and that they have a lot more potential than a 7m from the get go, but once you get into a MAJOR build it becomes the same game.

and your guess is very wrong, i have taken them both apart many times and once you get down to the motor you actually see how similar they are, bottom end diffs............
2JZ= 86mm bore 86mm stroke
7m= 83mm bore 91mm stoke
they are very similar, it is in the head that 2j excels

i am not arguing that the 2j isn't better because IT IS BETTER, im saying people underestimate the 7m, and id like to see more of them built well.

but i really would not like to continue this, because i dont want to ruin this build thread

[crazysupra2JZ]

yeah, i do need to change my name:)
see, that's another thing. the 2JZ has a shorter stroke. means higher rev limit. someday i'd like to rev it to 8.5k or higher. i wouldn't imagine trying that in a 7M. but then again that's also why the 7M has more torque.

thanks a lot for the support, i can't wait to do all the wiring for this thing. especially when i'm no good at wiring:)

Sorry man - I didnt mean to come across as condescending.

[crazysupra2JZ]

indubitably :)

[boostadikt]

yeah get ready for some fun, it will not be a small project for sure, but i also agree with what was previously said that it would be a good idea to mount a fmic and get pipes and exhaust ready, then you will have a bpu 2j and make 400hp :)

wellll....i'm not too sure what the difference is with a 2JZ from an Aristo. it only has 280hp...is it in the ecu that makes it have less power than the 320hp supra or is it in the twins. maybe the boost is set lower? i don't know...i need to find out though

[crazysupra2JZ]

got my engine....YEAH......http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0477.jpg

[againstdawall06]

The stock HP is listed as 280hp due to the "gentlemens agreement" the actualy hp is more then that. though it is a lil slower then the usdm 2j because of the cams and turbos i think.

good luck, i will be starting my 2j project soon.

[boostadikt]

how are the cams and turbo's different?

CT12's are CT12's and im pretty sure they wouldn't produce different cams for the same engine, when there is no need

[mobes]

USDM cams are more agressive
USDM turbo's are steel turbine wheels vs JDM ceramic
Also the JDM's have 440cc high impedance (saturation) injectors vs USDM 550cc low impedance (peak and hold)

It's the same engine, but then again it's not. There are many differences. Basically, the USA wasn't under the same restrictions as Japan, so they went all out on the USA version. The JDM version does have a couple things going for it though: it has MAP airflow metering, whereas the USDM version has MAF, and it has a completely different intake plenum due to the lack of EGR.

While the JDM 2J doesnt have an egr it does have the provisions for it on the intake. The only difference between intakes is that the JDM doesnt have a provision for the brake booster on the top. It has all the same egr crap inside its just pluged on the end with a pressed in brass plug.

[boostadikt]

for real?...... i always thought the main diff was no egr, and the MAP Sensor, i dont get why they would change the turbos and cams. that is another design and production that is not necissary. i would have thought they would just lower boost levels and detune the ECU, especially with the 440's

No EGR on JDM 2JZ (http://www.mkiv.com/techarticles/parts/no_egr/index.html)

I don't see anything there that resembles EGR provisions. Yes, there are soft plugs, but compare that to the USDM intake photos here:
USDM 2JZ Intake Photos (http://www.mkiv.com/techarticles/parts/intake_manifold/index.html)

Notice how the EGR attaches to the top of the manifold, above the large soft plug. Also notice within the manifold there is a tube extending front to back that is plumbed to that hole. Now I have never seen the inside of a JDM intake, but I would surmise based on the different location of the seam on top of the manifold that there is no EGR tube inside.

It seems that the Aristo motors are the only ones without the brake booster port. Every JDM Supra that I've seen has had it.

Japanese vs Export 2JZ (http://www.mkiv.com/faq/japanese_and_export_1.htm)

[crazysupra2JZ]

now i have a problem with the oil pan and sump... according to toyota... supras all have the front sump oil pan just like what i have now... but people are saying a supra oil pan will clear the crossmember but the aristo won't..i see no difference in this and the one i have now
this is a 94 supra turbo...same all the way up to 99...in 97 the part number changed

and that brake booster vacuum is by the turbos i believe. it looks like a pretty badass vacuum tube, i'm assuming it's for the brake booster

http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0494.jpg

[williamb82]

the front sump is for mkii's. the mkiii and mkiv are a mid sump. the aristo pan is whats needed for mkii's. so if you want to sell that front sump pan and pickup. lmk, im interested as id need them for a 2j swap into an mkii in the future.

[crazysupra2JZ]

well, the lower sump pan is crushed from shipping but the upper pan is good. i really don't think hammering it back out will work...i'm actually coming down to panama city this weekend for a car show, so you can take a look at it. you can meet me there.


edit*** i solved the oil pan issue. http://www.supraforums.com/forum/showthread.php?t=332028
and thanks to lowe toyota for giving me a good price on everything...

[againstdawall06]

so the mkiv oil pan WILL clear the crossmember?

[mobes]

so the mkiv oil pan WILL clear the crossmember?
Of a MKIII? Yes.

MKII Supra, Aristo, Chaser, Cressida: Front sump
MKIII Supra, MKIV Supra, Soarer: Mid (AKA rear) sump

edit: nvm i though the pic on page 4 was his

I have a set of usdm twins sitting in my closet :naughty: pm if interested.


The y pipe outlet on the usdm turbos is like 3" compared to the jdm 2.5".. little extra flow there too..

I removed all my ttc valves on mine, boost comes on quick.. no lag imo.. its a fun car, but I have boost creep problems.. .8 bar in 1st 1bar in 2nd and 1.2 in 3rd.. havn't tried 4th (that high in the rpm band.... 6k+).. gotta check for boost leaks and check my wastegates.. oh well..

GL with the swap, its worht it!

thanks , but i don't plan on keeping the twin setup for long anyway.

[crazysupra2JZ]

ok so i just bought a maf and 550cc injectors with rail and i am wondering if i can just put these in and get an AFPR and i'd be alright. i have a safc 2 to tune it with. but... mobes said that jdm has MAP instead of MAF. can i still use the MAF i bought? should i get a us mkiv ecu

[boostadikt]

MAP is better.... if the engine came with the ecu and harness use those and you can run the map setup, If you get a Usdm ecu you will have to run a MAF.

the us ecu and MAF will be setup to run 550's, but you can stay map and EASILY tune them out with the Safc.

[crazysupra2JZ]

what is the difference between MAP and MAF... i can't find a plug to plug in the maf i bought.

[crazysupra2JZ]

since i have no brake booster provision on the manifold. can i use a vacuum line off one of the turbos. i guess the first one. since the 2nd one isn't online all the time. or should i just take off the manifold and drill a hole through it to but the vacuum nipple in it?

[starscream5000]

I'd go with something more like what the factory does and go through the manifold, but don't use a banjo bolt like they do ;).

if your using your stock turbos, you would be better running them in TTC.

[crazysupra2JZ]

if your using your stock turbos, you would be better running them in TTC.

what is TTC? the line that comes from the valve cover to the manifold. would that be a good enough vacuum source? i just noticed that. i'm gonna be using an oil catch can, so instead of plugging up the vacuum line i can just use it for the brake booster

[tsuper92]

i wouldn't use the ttc(sequental) mode with the stock turbo's.i would run them parrallel to prolong the death of the rear turbo(if it isn't allready junk).the sequental system was nice for low end,but not realiability.the front turbo spooling the rear is hard on the turbo shaft.if the vsv's don't work then you overboost the front turbo.you might want to do some reading up on the set-up before you decide,because you might have to go single sooner then you wanted

hmm...well, i bought a T4 manifold for it already and i have a T70 from xspower. as well as a T3/T4 adapter. i did want to keep the twins on there to see how it felt. i don't want to increase the boost on them, 280 hp is good enough. that's about 80 more than i had with the 7M. but since the motor is still out i should just swap the T70 in now and save the hassle. and i can put in the 550cc injectors i bought. i bought stock ones from a usdm supra. i have an safc 2 so i can tune. but i'm not really sure what i'm doing there. i need to take it to get tuned.

but i think this weekend i'll put the single turbo in there...everyone seems to agree that the twins aren't that great

[tsuper92]

jdm twin's are garbage,the usdm will take you to 450whp.you will need to wire in a resistor pack for the usdm 550's(low impedeince)

If you're wanting to put on that xspower turbo, you'll definitely want to ship it off the John at MDC to have him clean out the walnut shells for you and give it the once over before you decide to put it on. If you a little confused as to what I'm talking about, PM him and he'll let you know what he usually finds in those turbos straight outa the box ;).

[crazysupra2JZ]

how reliable would the twins be at stock boost. until i can get my xsturbo checked out.

80 hp more is good enough! huh yeah right, who are you trying to fool!!!:nono:

I started out with wanting to run on stock twins and now my car isn't even done yet but coming out with over 600hp on single with fuel upgrade. Good luck!

[crazysupra2JZ]

yea you're right... i just bought a walbro fuel pump and now i all need is an AFPR. then the fuel system will be done enough for now. till next year when i do more upgrades to it.

[mrsuprafreak]

yea you're right... i just bought a walbro fuel pump and now i all need is an AFPR. then the fuel system will be done enough for now. till next year when i do more upgrades to it.

Yeah I know. And as far as being done for now I don't know about that.

I started out with a fuel pump to two then a custom dual feed fuel rail with 850cc injectors to a FPR kit to -8 feed with a -6 return and etc... You will be there soon also.

[crazysupra2JZ]

alright. i ran into a problem with putting the engine in the car. the sway bar on the botom... is that really important? cause when the suspension moves it hits the crank pulley...i could just take it off and be ok... and for some reason the front end is still like 1 foot in the air. like when you take the engine out... it still looks like that

this is what i'm talking about

[kylefoto]

I'd be weary about removing the sway bar...
That's just me, and I don't know a whole lot about suspension though. I'd wait for someone to chime in here.

[Evilempire1.3JZ-GTE]

dont remove the sway bar unless you drag race the car only!
you will have an avantage on launch if you remove front rear sway bars drag only.

when you drive on the street your car will handle like crap and have insane roll.

use spacer or washers on your motormount see if you can get your whole engine to move up a little bit or get a smaller crank pully like an underdrive crank pully

[tsuper92]

if that sway bar is moving up and down near the crank pulley,it's your suspension that has a problem.the swaybar should only twist a little there,not move up and down.

[bigaaron]

You must not have a transmission on it yet, because the engine is tilted forward. The valve cover is above the lip on the firewall, that's how I can tell. Once you put the trans on and bolt it up the engine will tilt back and away from the swaybar. :wiggle:

[crazysupra2JZ]

really. you're right the tranny isn't connected yet. man you're awesome. i was so worrid i'd have to spend another $500 just to get a new crank pulley... i didn't even think about that. i don't have the flywheel bolts yet. or the clutch..waiting for 935...geese. but i got the flywheel bolts from driftmotion. should be here wed... i was wondering why i couldn't find any info of other people having this problem

some more progress

[Mr.PFloyd]

how on earth is the upper rad hose gonna fit?

[crazysupra2JZ]

yeah...umm....i read that either a 1jz or a 2jz will fit with some trimming

[boostadikt]

damn you got this together fast...... very nice work so far.

[JBatt87T]

Good god man I didn't know you were doing this! I am uber excited for a ride now. If you need an extra hand let me know, I'd be glad to help!

[Evilempire1.3JZ-GTE]

Good catch!
The tranny does tilt the engine back!
Good progress on it. Bet you cant wait to drive it!

[crazysupra2JZ]

all i need now is a power steering hose and get some oil lines for the turbo. and i need to figure out all the wiring. oh yeah, and figure a way out to make the brake booster work.

do you think the vacuum line that comes from the valve cover to the intake manifold ill work. it's right behind the throttle cable bracket????

http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0520.jpg

[Brewster]

You must not have a transmission on it yet, because the engine is tilted forward. The valve cover is above the lip on the firewall, that's how I can tell. Once you put the trans on and bolt it up the engine will tilt back and away from the swaybar. :wiggle:

holy interweb diagnosis batman!

[crazysupra2JZ]

ok...so new problem

i just got done making a new harness for the fuel injectors. i hooked them up the same way the 7m was. cause someone said in order to use the 550cc injectors instead of the 440's i have to use the resistor box. looking at a supra ecu there are 6 pins on the ecu. one for each injector. the 7m ecu only has three pins. the injectors are grouped together. here's a pic of how i did it. does anyone have an aristo ecu pin diagram??



http://i62.photobucket.com/albums/h100/crazysupra7mgte/injsetup.jpg

[crazysupra2JZ]

well, finally got my clutch. but i'm a little worried it might have to go back. here's a pic why. so far i'm not impressed with spec. i found 2 things i didn't like about their clutch kit. and i didn't get any paperwork with it too. i'd liked to have had documentation with it but oh well.

[boostadikt]

^^^ ouch man, thats runnable and would not really give you any problems, but for buying something new i would want it to be perfect as well.

I am running that same clutch right now and honestly i have not been impressed... it has a lot of chatter and has some noise, so far it has held my power just fine, but its just not very smooth compared to other clutches. everyone that ive let drive my car has complained about the clutch as well.

in my personal opinion, send it back for the defect, get a refund and buy something else. I like the pulleys tho :)

well that sucks to hear. but i'll just use it for now and once i reach the threshold of the disc i'll just buy a better clutch disc. the pressure plate seems to be good. i only paid $475 for it because of all the hassle i've delt with through 935.

[boostadikt]

cool... what are your power goals?

[crazysupra2JZ]

400-450rwhp. i figure i can get that through tuning. after that i need to buy cams and stuff like that.

[crazysupra2JZ]

YAY more progress. I'm finally ready to put the engine in. and the guys at NAPA were kind enough to help me getting the pressure plate all setup.

[boostadikt]

^^ Very nice!.. what turbo is that? it also looks like you need to clock the center housing so the oil drain faces down.

[935motorsports]

We use that turbo on 1Js here. It should make sweet torque and spool up fast on a 2J.

[crazysupra2JZ]

i'm kinda worried about the spool time on it. it's the T70 ebay turbo. for the price it wouldn't hurt to try it. if it fails i can put the twins back in. then save up for a SP turbo. i'll also rotate the housing today so the oil drains straight down.

i have one of those hks copy wastegates... how do i hook up the vacuum lines to it? there's one on the top and one on the side.

[935motorsports]

You shouldn't worry, it spools nicely on a 1J, it should spool even faster on a 2J.

We rebuild them first.

[crazysupra2JZ]

MY HOOD WON'T CLOSE NOW....i guess i need to buy a t4 turbo so i can get rid of the T3/T4 adapter.

http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0579-1.jpg
http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0576-1.jpg

[jmoneydtb]

i thought it looked like that turbo was sitting a little too high with that adapter. i had the same kinda thing happen w/ my z car when i put the pathfinder intake manifold on it but you cant just get rid of a piece and have that kind of a part work right! so i had to shim the hood in the back about 1.5", at least you dont have to do that! :D

[crazysupra2JZ]

and where the turbo is i can't just cut a hole in the hood and put on of those air vents over it.


do you think if i bought a T3 weld plate and had it welded right on top of the T4 flange on the manifold it would be alright. or i can buy a T4 flange and weld it onto the turbo T3 housing.



i'm also about 95% done with the wiring i think. i doubt this engine is going to run when i go to start it.

powersteering hose
AFPR
Wideband



EDIT*******

i am now able to start the car but can't run it yet till i get the above items. i think i have all the wiring done. it cranks but i won't know for sure if it runs till the end of may
Downpipe
and some way to make my hood close

after that i'll be done

[crazysupra2JZ]

well, here's that latest and greatest.

right now i'm at apoint where the engine will crank. but i can't start it yet till i get a few more things. the wiring kicked my butt, but i won't know for sure if it's all right till i try to start it. i am so close. when i come back from tdy i'll have enough money to finish her. so now i'm expecting to get her done by the first week of june. the major part i need is a custom downpipe made.


some guy on a phone just decides to sit in my car will i take pics...geese

[Burntz]

beautiful car... get rid of those saw blades and lower it a bit ;)

hope you get it running soon!

[mobes]

Looks good. I like the IC setup.

How did you get the hood to close?

[crazysupra2JZ]

i had to cut away some of the hood support.


has anybody had an issue or heard of any problems with the TPS ??
it only shows 70% when WOT :(

[mobes]

First and foremost, make sure there's no slack in your linkages.

[p5150]

yeah and if the throttle body is opening all the way just adjust it.

[Evilempire1.3JZ-GTE]

I dont think the turbo wouldnt hit the hood if you either get the right header or had a 1jz cuz its over 1½" shorter in height.

Fantastic work I cant wait to see the outcome and dyno results of this.

[crazysupra2JZ]

lot's more progress. the engine is running but really needs tuned.
all i have left to get is a wideband and downpipe. what tranny fluid do you guys put in your R154? i need that too.


after all the wiring headache... the only thing i messed up on was the fuel pump. i had to hard wire it with a switch. and to confirm. the mk3 fuel injector resistor does work.

car sounds badass, course i don't have any exhaust on it yet

[ma70tt]

that spec clutch looks alot like a leftover act clutch i have sitting in my stock room. the one i have was bought for a 2jz/6 speed swap i did on a fd rx7 @ a year ago. let me know if you want it, i'll get it to you for way less than i paid. its the organic full faced disc (no chatter/noise) and the pressure plate is pull style like yours... if ya look in old for sale posts its in there. i also have an extra 6 speed trans here too...

[crazysupra2JZ]

alright, so the TPS is fixed. i went into the AFC and adjusted settings in it. so now it shows 100% when WOT. but... does anybody know which signals i need to create to make TEMS work with speed and braking and all that happy stuff.

[p5150]

Theres only three wires from the ecu that feed into the TEMS. The other ones look to be independent. Ive been looking to see what the wires that come out of the TCCS that feed to the TEMS actually "say" but I cant find it anywhere.

http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?Section=Main&Page=115

Thats the tems - TCCS pins 17, 18, 19 if you have a turbo. B1 connectors 2, 3, 4 Look at connector B1:

http://www.supras.nl/index.php?option=com_content&task=view&id=34&Itemid=50

You probably had that already and I havent been any help - I dont know what you are going to do to simulate the signal because I dont know what the signal actually is!

[crazysupra2JZ]

yeah this wiring is a little on the hard side, but do you know what wires to jump to make it stay in full firm mode. i've seen a thread about it before, i think on SF though. at least i can make it stay in which ever setting i want

thanks for the help though, looks like it's kicking your butt too...

[CF_Sapper]

subscribed gonna finish readin the hole thing when i have time

[Big Rob]

[QUOTE=crazysupra2JZ]yeah this wiring is a little on the hard side, but do you know what wires to jump to make it stay in full firm mode.[QUOTE]

Couldnt you just remove all the TEMS servo motors and click all the shocks onto hard and leave it that way?

[crazysupra2JZ]

I'll have to read into that. plus if i get rid of the actuators, i think the MKIV TRD strut bar fits, anybody know for sure.

anyway, got an update on parts. still at nellis for now but as soon as i get back to GA i'm gonna finally get this car on the street

here's what i ordered

NGK Powerdex AFX Wideband O2
Eibach lowering springs 1.5 F - 1.0 R
Aeromotive Fuel Pressure Regulator
ATP Turbo 3" V Band downpipe. it's a start to getting my downpipe made up.

so now i need me some slotted rotors and maybe MKIV wheels...

[SupraOfDoom]

I'm really jealous.

[crazysupra2JZ]

if anybody can help, i ordered Eibach springs, and GR-2 rears. i am going to get the AGX for the front soon enough, but my concern is, would it be safe to use the Eibachs on the stock TEMS struts? just for a little bit, until i have enough for the front struts.

oh yeah, anybody got any tips on breaking in a new clutch and turbo. i've read something on SF but didn't help too much.

I ran Eibach springs on stock tems shocks for several years on my 1jz Supra, it worked very well setting the tems on the high setting after removing the actuators. The ride was great for a daily driver.

Nice work on your project, by the way. It looks great! Should be a lot of fun :evil2:

[crazysupra2JZ]

so today while i was working on getting my springs in, a group of younger kids stopped by to see what i was doing. they wanted to see the engine and as soon as i opened the hood, they're eyes opened up wide and all of them were like, man look at that. one kid asked how fast it will go, he was like 200! i said around 150. so i am glad i made their day.

i got my NGK wideband in too, still need to wire that up, and i picked up a Bosch replacement O2 for the ecu to look at

as she sits now...
http://i62.photobucket.com/albums/h100/crazysupra7mgte/100_0617.jpg

[crazysupra2JZ]

got my springs in, car looks freakin awesome, totally different. i love it
you probably can't tell, but before the front end was so freakin high, it looked like a 4X4

[suprahero]

:love: :drool: :love:

I'm a man of few words...........:biglaugh:

[crazysupra2JZ]

i figured out my problem of not revving past 3k... kinda

i checked the IDL signal and it was getting 12 volts. so i was like what the hell, so i cut the wire. then i was like, ok i'm sorry, i'll fix you.
so i soldered the wire back together, and started the engine up. and now it revved way past 3k, problem is gone.

oh, and where do you suggest putting the O2 on the downpipe. it says between 10 and 2 o'clock. how many inches away from the turbo would be good. i figure about 6 or 5


i did have a nice video of my car revving, but somehow the loud exhaust made my camera take a crap and messed up the file. so all i have is the walkaround... i'll try to get a better video of it revving

[Mr.PFloyd]

sounds SUPER MEAN! :D

[crazysupra2JZ]

well, these new springs suck...car is extremely bouncy...other than that.. i threw away my $400 digital video recorder and my $250 digital camera last night... i thought the bag they were in was trash... i am very pissed right now but happy cause i finally got my supra back on the street today!


does anyone know if the traction control TPS is the same as the other TPS ... mine is broken and i've tried using the TPS from TCCS(i think that's what it's called) but it reads 28% throttle.

[JBatt87T]

Damn man that is nasty, youve brought this car a long way. Did you move out of the barracks? Anyways, the car is nasty and I think its time to go for a lil cruise whada ya say?

[crazysupra2JZ]

once i get my downpipe finished, and get it tuned... i got no problem taking you for a ride, i noticed the pools open again , you working out there again this year? i'm still in the dorms, freakin hate it

[jmoneydtb]

i know this is somewhat a delayed respones but, as far as breaking in a clutch, i would at least put 300 miles on it before giving it full power, do a lot of stop and go as well. might want to put around 500 or more before trying to launch it or track it. as for the turbo, as far as i know there isnt really a break in. might not want to go full kill at first, for the sake of your drawers.

[crazysupra2JZ]

thanks man... i'm not gonna take it any faster than 45mph. lot's of stop and go around here, oh... at 5pm

[JBatt87T]

Sounds good. Where you working on it at? Nope Im working at The Red Tomato up in Bolingbroke. Where'd you get your piping done for your intercooler? I need to hook mine up soon, its just collecting dust in my room right now lol.

[crazysupra2JZ]

i just bought a kit from ebay. it had like 6 or 7 90 degree pipes with rolled edges, came with good silicone couplers instead of the crappy rubber ones, and T bolt clamps

a girl at work let me use her garage. i tore that place up...lol

[crazysupra2JZ]

BUILD COMPLETE

i got my exhaust done, the downpipe came out good, no leaks at all. i wish i could take a video of it, but i no longer have any camera..:(

mmmmm......no

no money for that, plus a problem arose today. not idleing so good. next year though, i'm going to a meet.

[crazysupra2JZ]

anybody know what the tool is that makes the beaded edge around pipes. i bought intercooler pipes that have a beaded edge but a couple pipes i have on don't, which keep popping off.
