More Boost!?!?!?
well here is the stroy...i was walking through the hall at school and one of my friends said that the factory turbo on the WRX can push about 18-19 pounds of boost with no other engine mods...just a simple boost controller.
Is this true? Does anyone think that this is actually a good idea? i like the thought...going a lot faster for not a lot of money.
Should i open the exhaust first? Is there something i might DESTROY by doing this to a stock engine? I have been into cars for a long time but mostly NA engines. I don't know a lot about turbo yet...which surprises me considering i now own a WRX. I'm trying to learn but as much input as possible would be greatly appreciated. Just please answer my questions and any other USEFULL advice would be great. thanks.

Somebody on this board just blew their motor on 18 psi of boost not too long ago. I would suggest doing a lot of homework before remotely attempting to do anything to your car. The "cheap" route is seldom the safest one when it comes to performance upgrades.

I would just like top say good job on asking first! Yes the turbo can put out 18 psi, I think the stock is raited up to 21psi. And yes you will be able to go alot faster...for a bit, but you will blow your engine. If you are looking for more power a good place to start is the exhust. Never heard of a blown engine from that. As far as boost gos, Iwould leave that up to an new ecu. A new ecu will raise your boost, but also alot of other stuff so that the engine can run the higher boost safely. When raising the performance of your car try to think of it like this, all your doing is releasing the power the car already has, insted of tring to force more power out of it. Things like silicon hoses, for better air flow, and a well built exhust, agin for better flow will go a long way. Hope that helps alittle.
i would have to disagree. the stock turbo can't handle anything more than 16 at most 17psi (not very safe). the stock turbo is too small (compressor and turbine) to push up to 17psi safely. up to that point it's basically blowing hot air, which is what would cause detonation to your engine due to premature combustion. take this advice, don't even try to boost that high. just buy a bigger turbo. most aftermarket turbos may lag a bit more than the stocker, but it will push far more than the stock one and safely. also, it doesn't matter how much boost you run, but is how you tune it and put it to good use. i think that with just pushing 16psi max and getting your set-up properly tuned will benefit you the most in terms of reliability, power, and safety. why risk blowing up your engine out of stupidity, which is what some guy did on these forums. just remember, "ENGINE MANAGEMENT" and "TUNING" is key to everything

I disagree. The stock turbo can reach 18 psi. I know a docen people running 18 psi at the track with proper tunning for more than 30k miles and haven't had problems. They are getting 12.8sec on the 1/4 mile with only stg 2 mods on stock turbo. I wouldn't try it myself, but it has been done.
the ion upgraded stock turbo would be able to handle 18psi of boost with no problem, but not the regular stock turbo, at 18psi like jenisonwrx said, it won't hold boost and basically it will be out of it's peak efficiency. take a look at this thread:

All I can say is that everyone that I talked to that knows a lot about this (my friend is a mechanic for Bell Subaru) says that 16psi is the highest boost you can safely run.

you spent the cash for a WRX, why dont you invest in a turbo upgrade and do it the right way. larger turbo, fuel pump, injectors, etc? yes you can run that much boost, but for how long??? try it and find out. is it worth it? IMO no.

Stock turbo
Thought the stock turbo was pretty much out of it's efficiency range at more than 15.5. I wouldn't run more boost than that with the stock IC. But that's just me.
