[STI133]

Iam about to get an STI here in a couple of weeks and I was wondering if any of these parts iam going to list, will fit right and work right on the STI, since there for a 02 and up WRX.
Intake
Exhaust
Up pipe
Down pipe
blow off valve
front mount intercooler
full coilover suspension
front and rear strut bars
Thanks for your help.

I dont think any seeing as its a different engine, Tranny, etc.... maybe the BOV....

intake, exhaust will work.

Up pipe....no need. the pre cat turbo is gone.

down pipe....should work.

BOV...unless you are venting back into the intake, don't use it. Really no need for it unless you are pushing so much pressure the stock bypass isn't holding.

front mount should work...but again, unless you are at high boost and hp numbers, you shouldn't need more cooling than the STi unit.

full coilovers....the stock suspension handles better than any current aftermarket suspension system. If you wonder about this, check out the current SCC which had a few tuner cars up against the STi. The only car to beat it in handling was the Vishnu car, but that can be accounted for by the R compound tires.

Strut bars...not needed. the STi chassis is reinforced at the frame level so that bars are not needed. Trust me, when you feel the car, you will have no doubt it is solid enough.

Hope that helps.

only reason to replace uppipe with aftermarket is probably better flowing design.

they probably have tons of bends and kinks on it...

there must be suspension improvements since it still trys to push the nose out. something could be tightened tweeked or reworked.

 

[CloNeGTS]

There isn't enough room for an uppipe to be overly bendy....have you seen one? The only diff between aftermarket and a standard WRX is the material used and the lack of cat.

I don't think you'd have any reason to go thru the torture of replacing the stock STi unit...unless you were already back there for the downpipe and you were bored.

A slightly larger sway bar will probably fix the front end plow some people mention, but as also mentioned in other threads, it seems the car doesn't display this tendency when driven properly...which is a little difficult to learn apparently.

the asfalt and road tests that i read said front end push was the only reason it lost lap time. of course it made up buku time in the straights. millen didnt like the fact you couldnt turn off abs. that was fixed in my hf integrale with a push pull c.b. by the e-brake. worked well

meant asfault and terra my apologiessin52,

the reviews i read say tha it pushes out. i dont see how it could need to be driven properly compared to other performance cars. my wrx does a push but i expect it. i guess i just figured soa would have eleviated this problem by now. all three subarus i've driven have had nose push. my lancia hf integrale was awd and didnt nose push. also why doesnt the evo nose push. it is much nicer to have the rear end slide out then to go farming nose first. also these guys and gals test drive a lot of cars so most of em are not dumb.

p.s. i am still on the waiting list for an sti no other option imho.

The reason for this 'push' people are talking about it the front diff. Some folks are now learning that you need to get a feel for the car and the way that the front diff needs to be used....namely....stay on the power.

Quite a few people have commented on NASIOC that once you get a feel for it, the car just seems to pull itself right around.

so stay on the throttle and it should come around not push. this is gonna be fun. also is the front diff similar as the evo7 jspec ffront diff?

Re: wheels

That's the idea anyway. Apparently if you keep the diff engaged and pulling, the front just stays right where it is and pulls the circle perfectly.

I can't wait to feel it....it seems to make sense.

In a way it's almost like a motorbike, ease on the gas before the corner and give it more once your in the turn. That's the way I drive this car and don't feel any understeer at all. Don't forget guys this is a rally car not a NASCAR, it will not drive like a high performance rear wheel drive car. Just point and click the front end and the car will follow smoothly into any turn. One should never try braking while turning anyhow, unless you need to stop obviously.
