Forums Forums Enthusiast Forums A - Z Autowirral I have my bits

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

Its about time you made that thing of yours a bit faster matey

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

lmao at the IC grid full of flies!!

gimmie the turbo

should be good when its on

you have an uprated fuel pump dont you?

yeah thats gotta go on too, cant remember where i put it tho

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

bloody hell mate, bit techy that, im confuzzled lol

brakes are goin on this afternoon, off now to get some pics for before and after.

Pics up later on

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?

All this talk is too technical for me but nice 1 john, hopefully beef it up.

standards are 550 from what i can gather, it was all mapped for a car running standard injectors so we should be okays
