I am looking for a turbo that can give me the following on a 2.35 build engine:

- fast spool up (asap)
- about 420 Bhp without running mad boost (about 20 psi)
- being able to run high rpms (272 degrees cams !) and still providing enough air

Is this even possible, if so what would you recommend Kev ?

Hi,

in answer to both of these questions the SC46 Billet direct fit would be ideal, however on the 2.35 engine I would go to the extra expense and fit a rotated GT 30 Billet, the bottom end you have will be well caperble of dealing with it.

Graph below is an SC46 Billet on an STI 2.0 ltr, I must point out this car was 20 BHP down when we ran it before mods and has stayed that way all throughout testing, maybe its a friday car.

On the road the car is stunning, spool loads quicker than on the dyno.
