So working on a friends 1jz. Everything stock. First issue is no power to coil number 6 only. My main question is, is there anything in between the wires from the igniter to the coils or is it just straight wiring? I was thinking of checking continuity from igniter plug to coil and seeing if...

So the 1jz i'm messing with has 1 blue and 2 black wires for the oxygen sensor, no connector. The colors for the o2 sensor connector (wiring harness side) has a red, white, and black wire. Which wire goes where? I'm sure the two black wires can interchange, more concern where the blue one...

Hi, helping a person finish up his project. the engine is installed and running, but still need to identify the o2 sensor plug. is it this one? http://imgs.inkfrog.com/pix/tpmsexpress/possible_o2_plug.jpg?i=1362769292238 The o2 sensor we're working on right now looks like this...so we...

After eating I took my wife to drive around because we didnt want to go home and watch t.v. all night. I decide to hit the highway...purposely looking for something fun to race. I havent raced anything on the highway for a real long time now..(aside from an Evo 9 which is no biggie on the...

transmission gets sticky when its hot out or after doing city driving for awhile... when its cool..it'll feel perfect. going into 1st gear i have to almost force it in...BUT..there is no grind..just super stiff. mainly 1st and 2nd..all other gears are okay. AND its not ALL the...

well after a dissapointing dyno run, 366 at 15psi, crower cams, t61.. i was confused as to why my dyno was so low. at first i thought it was my spark plug because a couple of the runs broke up real bad up top. i put new plugs in it and it fixed the breaking up part, drove like normal and pulled...

well i dyno'd her and i'm pretty dissapointed with the results, but at the same time i can see why i got these numbers. i knew i should've put the 6097's in before i ran her. mods at 15psi- t3/t61, 440s(540's waiting to b clean), safcii, 3" i/c pipes, 3" exhaust, crower 272s it was...

alright. i know lots of people know this already and lots of people dont so i'm writing of how i did my cams. please give remarks as to do something better or if i did something incorrect. this was my first time working on a jz motor. must have items (imo, unless recently replaced) 1. cams...

installing my cams this week and the only question i have is how does the timing belt tensioner gets its tension? this is my first time digging into a jz motor and never seen this set up before. looks like some kind of hydraulic something something pushes up against the little pin connected...

was wondering if there's any drastic negative effects of putting a t3 to t4 flange on instead of just cutting the t3 flange and putting a t4 flange on? i mean obviously it would hurt spool but how bad? i would imagine too that a turbo that can breath better would be somewhat cooler...

well i think its time to upgrade this tiny t3/t4 as its leaking oil and imo takes too much psi for 350rwhp. i'm aiming for 450rwhpish 500 on race gas.... i just got my 272 small core crower cams in too..so that should def help. main question is, has anyone had any experience with...

well i think my greddy profec b stepper motor finally crapped out all the way. at first it was just little by little..now it doesnt work at all. i just get waste gate spring pressure regardless of what i do and how much i adjust. i cant find anyone who sells just the stepper motor so i'm in the...

my engine never came with an idler pulley assembly. the previous owner...i dont know how...fabed something to tighten the alternator cuz they relocated it...but now i have moved the alternator back to is place and put in a power steering pump. the way i have it now the pump just pivots up and...

my 1jz never came with power steering pump and i'm getting ready to put it back in. i think i have most of the parts and a guy sent me a 2jz pump with bracket... i was going to buy a used1jz bracket from a member here till he showed me a picture and i realized that the 2 brackets look almost...

i have an safc and from what i've read, i heard that you wont need a boost cut controller.... my question is..will i ever need one if i raist the boost? i tried raising my boost today and 18 and down is fine and dandy but anything sleightly over that and it hits a brick wall....is this...

i have the greddy profec b II installed and at first it worked flawlessly. boosted to 18psi with no problems...then all of a sudden it would make this weird rattling noise from the stepper motor. whats weird is if i sometimes adjust the balance knob to mild it'll get worse(louder noise)...only...

am i reading wrong or do i see some people upgrading just the exahust cams? would that even make sense? i would understand just the intake...but i dont understand why anyone would do one w/o the other. just wondering if this is common practice.

most of you would prob know me from supraforums.com as wu_tang here is a vid of my truck that some people requested. horrible quality and edit. sorry. http://www.youtube.com/watch?v=b9-fmEvcml4

okay so i tried to research but i keep getting all sorts of answer. my first and main concern is. 1. are the drive shaft yoke different? meaning i cant take the w58 driveshaft and stick it in the r154 correct? 2. speedo cable the same? 3. i have w58 mated to 1jz, i dont need a new...

something weird is going on...i go to the dyno and i boost to 18psi fine. i have safc stock 370cc injectors 2jz map. nothing weird at all there. after that...now when i hammer on it and i hit almost full boost the car almost pauses for a good second...like it wants me to go slower...go...
