i just bought a 02 WRX with a couple mods. as far as i can tell right now it has a catback exhaust, turbo timer, and bov. i'm going to order a boost controller asap. what is the best boost controller for the money and what other parts should i purchase with it to keep my engine running optimal? also what is the best site for WRX performance parts at a great price? thanks guys.

i know there is already a thread about this but i also was curious about how much boost i can run on a stock engine and how much horsepower that would get me. also with that psi what other mods should i have done? thanks

If you're looking for an electric or electronic boost controller, you might want to read this - http://www.arimport.com/forum/index.php?showtopic=490

If you just want a manual boost controller, they all pretty much work the same.

edit: actually, there are spring type and screw type MBC's, and they work differently, but all the spring type work the same and all the screw type work the same.

i'm sorry i wasn't able to find the exact info i was looking for on that. where is the info. on how much boost i can get the boost controller up to on a stock turbo. sorry guys i guess i'm just not finding it on there. i thought i read through all the info pretty thoroughly. thanks

i have had a joe p boost controller for about a year. It hasn't given me any problems at all. You can get one at www.boostcontroller.com

will someone please tell me how much boost i can crank the stock turbo up to providing the best power increase without worrying about blowing anything?

Not much. I wouldn't go over 16 psi with no other mods if it were my car.

15.5-16psi

what about with a downpipe, catback exhaust, turbo timer and bov? or does that even make that much of a difference?

also how much more horsepower do you think that will give me?

The turbo pretty much maxes out between 15-16psi. I have heard that for ever pound of boost you can expext 10-15hp. You will definetly be able to tell a difference.

thanks a lot man i appreciate it
