boosted integra & newer mustang

[supraboy]

my friend recently got his 96 integra ls boosted and wanted to race me. so i met up with him at the skate park and we decided we'd do a few pulls. then one of our friends with a 01 or 02 mustang wanted in on the action too, he had a cold air intake and exhaust. so we pull out to go to one of our safe spots and immediately the integra romps on it and blows my doors off :aigo: i gotta admit i underestimated him, granted i didn't know we were going, i still couldn't catch him. anyways we got to our place. and we lined up mustang, me, integra, we must have been mashing for like 30, 45 minutes, lets just say i didn't win a single f ing one. i was so pissed at the end of the night!!! :icon_evil i don't understand, my mods: 3" exhaust, turbonetics t3 ceramic ball bearing turbo, rebuilt head, newly installed maft pro ( i didn't know how to use it :3d_frown: ) but still the mustang pulled away from me every time by atleast 2 or 3 cars. the integra we never really lined up against again, but when i was behind the mustang he was no where to be seen, later he said that he pulled out early cause he was spitting bolts lol.

owned, where i wa. are you? I could help "some" as far as your maftpro issues are concerned if your anywhere in the southeast sector of wa.

[Nomad707]

mustangs can be woken up VERY easily (as with any v8)

it only takes intake and exhuast on a v8 300CI (5.0) or the smaller 4.6 V8s.
v8's take very well to these mods, and can really slam down some good HP with little effort.

a good example is a foxbody mustang 5.0

ya his was the 4.6 liter, and i really underestimated him, but he said that hes only running 295 horsepower, with my mods i should easily be in mid 3's right?

[Nomad707]

well since you dont know how to use MAFT you could have a crappy tune.. (no offense)
do you have supporting mods for the turbo? injectors? fuel pump? AFM?

none taken, thats what i get lol. no but i am running on speed density mode, so i eliminated the afm

[Nomad707]

well if you dont have 550 injectors and a 255lph pump.. you will run lean and crappy.. and sooner rather then later, you will blow stuff up.. this is commonly discussed. when upgrading the turbo, you must install supporting mods.

ive raced a couple of ls/turbo civics and i did pretty good and my car was pretty much stock then. 3in exhaust apexi intake stock boost (4psi in colorado) stock turbo :P they were set at 15psi


they were manual i was auto, they had me by the time i hit third gear

of course a civic with a turbo = major lag

[supraboy]

ya but they weigh like 1/3 of what we do lol, damn you heavy supras lol.

[shaeff]

^ yes, but keep in mind that turbos spool under load. no load= very little/no spool. ;)

it really is a trade-off.

-shaeff

[chris717]

didnt know that....
i raced a civic hatch with a Gsr and beat him until 5th gear where my n.a slows down.....
i need turbo

[supraboy]

lol ya i don't have an excuse... except i don't know how to use my maft pro yet lol.

[Jaguar]

I raced a turbo Civic in my old 7M 60-1 and though it was close, he pulled on me and made me feel :nono: The thing looked completely stock except for wheels, but this is L.A., everybody has wheels! He kept looking over at me, and I knew that I was going to stomp his ass so I shrugged my shoulders and revved at him. We went for it, and that's when I heard the turbo. :aigo: :1zhelp: He had about a car on me when we shut it down. He got a huge thumbs up for that one.

Edit: I did have a boost leak though.

[supraboy]

ya it does really piss me off when civics get turboed, lol cause then they're deadly. but luckily this kid was my friend so he was nice lol.

[7Mboost]

You should've taken the Mustang easy somethings wrong.

[supraboy]

You should've taken the Mustang easy somethings wrong.

ya i know, i really need to figure out how to use that dam maft pro lol

[supramike7m]

dude you went about upgrading your supra totally backwards. you have an upgraded turbo, with no fuel mods, no hardpipes, no intercooler, no boost controller, no wideband to tune in the first place. turbo upgrades should be the last thing on your list of upgrades.:3d_frown: no wonder you got smoked, your probably runnin like shit.

[supramike7m]

ya but they weigh like 1/3 of what we do lol, damn you heavy supras lol.

that has nothing to do with it. well maybe a little. what kind of exhaust do you have? do you have an 3" elbow? that will free up alot of power. intake? any kind of boost control? next you need to upgrade your fuel system before you break shit. get a pump, injectors, afpr. your also need to get a wideband of somekind before you even think about fuckin with your maft pro.

[supraboy]

weight has a lot to do with it, especially when i out weigh him by like 2000 lbs. but ya i have a manual boost control, plus the maft pro, and it was my dads car before mine, so he did all the turbo work, and i should be ordering my 750's and a walbro 255 pretty soon, is a wideband really that crucial??? if so what brand is recommended

yes a wideband is crucial, with an upgraded turbo on there and no fuel system, your goin to blow it up. you cant even think about tuning your maft pro without one. wow, a 1500 lb integra? thats the lightest street car ive heard of. no way you out weigh it by like 1000 lbs.

[supramike7m]

read this, it would be good for you to follow. like i said a turbo upgrade should be the last thing on that car.

Stage 1:
Intake, 235bhp @ 7psi[/size]
The first thing to do in increasing any engine's performance is to make sure it can flow plenty of air. The simplest way to help an engine breathe better is by installing an aftermarket intake. There are many different brands out there, but Apexi performed the best in this test. For hints on installing a full intake kit, please see this tech tip. While you are at it, I also recommend the SOGI cold-air intake mod.


Stage 2:
Cat-back, 250bhp @ ~8psi
Continuing with the theme of better breathing, the next step is to install a cat-back exhaust. There are even more brands and styles of exhausts than intakes, so take your time and find one which best fits your needs for flow, looks, and sound. If you live in an area where corrosion is a problem, you probably will not want to settle for anything less than a full stainless system.


Stage 3:
Downpipe/elbow/primary cat or test pipe, 280bhp @ ~9psi
If you still want more power, then its time to replace the restrictive stock downpipe, turbo elbow, and secondary catalytic converter. This picture shows one of the simpler downpipes, although there are some downpipes that integrate a turbo elbow and test pipe in one unit. For the environmentally concerned, Random Technologies makes a high-flow cat that will replace the secondary cat, but it obviously will not flow as well as a "test pipe." One word of caution -- downpipes are not legal in all states as they replace the primary catalytic converter.


Stage 3.5:
Gauges
While gauges do not increase power, it is important especially if you want to continue modifying. At this point, you're probably already boosting 9 psi, which exceeds the stock boost gauge. Installing a new one, along with an Exhaust Gas Temperature (EGT) gauge is also a good idea. An Air/Fuel ratio gauge is also good, but readings based on your factory O2 sensor are next to worthless so a wideband 02 sensor would be necessary. Other good gauges to consider are water temperature, oil pressure, and oil temperature. If you can afford it, look for gauges with a peak hold feature. These can be very helpful, as you cannot always pay close attention to your gauges when you are driving hard.


Stage 4:
Boost controller, 300bhp @ just under fuel cut
Now that your engine can breathe freely and you can monitor what it's doing, it is time to turn up the boost with a boost controller. There are inexpensive manual boost controllers out there, but I have found it to be a pain to get out and adjust them every time the weather changes. The solution is an electronic boost controller which can not only be adjusted from inside the car, but some can also learn to better control your wastegate allowing the turbo to spool much faster.


Stage 5:
Intercooler and hardpipes, 320bhp @ just under fuel cut
If you still want more power, you will need to replace your stock intercooler and the restrictive stock intercooler piping. Compressing air creates heat, which can lead to detonation. Since you want to turn up the boost even more, you'll need an intercooler that can not only flow better but also do a better job of keeping the air cool. It also is a good idea to replace your factory bypass valve to prevent compressor surge.


Stage 5.5
fuel pump
When you try to boost too high, your ECU will cut fuel momentarily to prevent engine damage. Now that you want to exceed that limit, it is time to upgrade your fuel system. While it is possible to boost a little over fuel cut on the stock fuel system, it is not recommended -- especially if you have your sights set significantly higher. The first step to upgrading your fuel system is to then replace the fuel pump with one that can move more fuel. Walbro and the stock MKIV tt pump are common choices.


Stage 6:
Lexus AFM/550 injectors, 340bhp @ 15psi
One of the most common ways around fuel cut is to use an Air Flow Meter off a Lexus V8. The basic gist is this air flow meter allows some unmetered air through tricking the stock ECU into thinking it is getting less air than it really is. Because the ECU thinks it is getting less air, the boost at which you hit fuel cut goes up. To offset this extra air, 550 injectors replace the stock 440 units. Details on this upgrade can be found here. Recently, PHR has announced they will make a "map ecu" that will allow consumers to use a much less restrictive MAP sensor instead of an AFM. Details on this product can be found here.


Stage 7:
Fuel tuning device and dyno tuning, 375bhp @ 16psi
At this point, the car could benefit from some fine-tuning. Chances are you will be running rich, so an air/fuel controller can lean out the mixture and help further raise fuel cut. There are many options out there, so do a little research and decide on the best unit for your goals. If you must have the best, a standalone is the way to go but it is much more expensive, and is more difficult to tune (chances are you will have to have a professional tune it).



Stage 8:
Upgraded turbo
You have now reached the useable limits of the stock turbo. It is possible to further increase the boost, but the turbo will be blowing such hot air that you will experience diminishing returns. Which turbo you go with will depend entirely on how far you want to take your Supra. If 450bhp or less is ok you can go with an upgraded CT26. 550bhp or less and you can go with a bolt-on hybrid turbo. If that is not enough, then you will be looking at a bigger turbo that will probably involve some custom work. If you do have your sights set that high, you probably know what you’re doing or will be taking the car to a professional.

haha.. i went from stage 2 to about stage 9 . woops

lol ya me too, and now im re-tracing my steps

[BiGGinZ]

:sarcasm:

[supraboy]

i got my 750's and my walbro 255, now my only question is how hard is it to install them?? do you guys recommend bringing it to a shop, or is it a couple hour job, or a weekend job???

[Kosh]

Just to make it clear i personally have not done these upgrades yet. With that said though, i have removed my gas tank and i can tell you that alone is a good days work. If i were you, i would reserve the weekend, or a couple, for this one. Otherwise take it to a shop. just my .02

[Snotcycle]

ok mistake #1: you bought a huge turbo with no supporting mods, thats been covered nuff said.

mistake #2: you bought a maft pro without a wideband,
btw are you usinbg the maft pro for boost control or just fuel?

about number two, you should check out HPF's site on the maft-pro

Dropping the gas tank takes an hour tops. As long as you have the right tools, its an easy job.

[shaeff]

1) get the maftpro from drjonez here on the forums. he knows THE most about it, and has incredible tech support

2) why 750cc injectors?

[Kosh]

How did you remove it? Mine had so much undercoat and the rust on the bolts, i couldn't get em off without worrying about snapping em. I got Bolt buster though which would help.

[swaq]

wow, a 1500 lb integra? thats the lightest street car ive heard of.

My dream....

[OneJArpus]

i went from stage 1 to 1JZ =P

[85?]

I didn't know an integra weighed 1500lbs. It is more like 2500-2600lbs.

it sounds like he forgot to put the engine in it.....and drive train.....and suspension.....lets just say its a chassis......

You gotta watch out, dem rooling jdm chassis's are FAST LIKE A NASCAR with ICE LIKE A SUPERSTAR! WOOT! ;)
