I have a 2006 WRX 5MT, it is currently stage 2. I have purchased a VF39 turbo, some 2004 STi injectors, I will be buying a TMIC and Walbro Fuel Pump.
I have heard that the spoolage on the stock WRX is alot faster than the STI, at what RPM's will the turbo kick in? and is a Cobb tunned, or pro tunned WRX faster than a stock STI?
Possibly just a dumb question but Im curious.
