Yep, been and got the bits for the car today, the ball is finally moving and im only a week behind scheduel. The car the bits have come off has been rolling roaded @ 359 Bhp with 335 ft/lb torque so fingers crossed STi 6 Intercooler TEK3 Custom remapped ECU peaking at 22 psi boost (1.5bar) Prodrive 330mm front brake upgrade, calipers are still on the other car these are just a spare set of discs but you get the idea on size IHI Turbos VF35 STi 8 Turbocharger This is the thing that will make it flyyyyyyyyy

leaving pistons as they are, will be runing it about 20 psi, the increase in power around the 50 - 80 mph mark is what im after, the turbo spools up and keeps going. Engine should be ok (fingers crossed) if not its time for a brand new one

i presume you mean 50 - 80 BHP and not mph You are hitting DANGER Zone running 20psi boost but you have a slightly larger intercooler to help cool the charge temperatures. Have you worked out how to eliminate the Fuel Cut yet ?? Dont forget this kicks in at approx 16 psi.

fuel cut is eliminated by the remapped ecu mate.
I meant mph yeah, the pull in 3rd between those speeds will be immense

Shes coming together matey At what point do your std injectors max out? That interwarmer should help, but can the injectors flow enough? Have a look here to do the calculation

Basically, without working out the increase in fuel pressure from the new fuel pump, and keeping injector duty cycles within the safe 85% you need 550cc injectors to safely support 360bhp The increase in fuel pressure should help the std injectors, but maxing them out is quite dangerous - once they go above 85% duty cycle, they pulse so fast they can lock up and stop feeding a cylinder What size are your std injectors matey?
