does anyone know what sort of ower increase would the above give me on my98 turbo with kn induction and 3 inch straight through exhaust from the downpipe. plus it is pushing 15 psi and i have a manual boost controller can i up the psi safely and if so what to.

cheers

better asking in drivetrain 15 psi/1 bar is bordering on fuel cut though

check out here, my 98 uk wagon run 269 bhp at g force a couple of weeks ago with de cat, k&n and boost running 1.2 ish bar

clicky thingy

edit: bottom of page 1 & start of page 2, should give you a rough idea what to expect, car started life standard @208 horses

i thought 1 bar 15 psi was standard am i wrong

matieboy

my97 uk ran 0.8 bar standard

how would i know weather i had uk standard, uk wrx, import wrx, or what engine is in my 98 because i know it is not the original, i was told when i bought it that it had a wrx engine put in it which was built with sti internals in it how will i know

matieboy

all 2.0 impreza engines are ej20's its just turbos and ecus are different between uk and import sti's have forged internals

jogyp

well how come some have red top engines, how will i know what turbo it is and ecu i was told the turbo was a small one?
