the turbo specs are about the same as a VF30 or 34

If your going to put the turbo on the WRX the ECU will fuel cut at 18psi & throw a CEL

you have an STi? i wouldn't screw around with boost controllers on a $30k car. wait a bit and the ECUTEK software will be able to tune that car and it's much safer and effective than a boost controller.

well if you can't control the fuel for the added boost.

DON'T crank up the boost. You'll blow the engine

You need proper fuel management to do that

Go for custom dyno tuning. I have a pic of a guy who's turbo blew out of his hood because of nonsense like that all black and burned. Get some bolt ons then go for the custom dyno tune. It'll do good.

i believe that the sti has a vf30 turbo in it. but i agree with WRX_2NR. if you don't have the fuel the bump up the boost don't do it.
