Can somebody help me with my cossies turbo lag, I want the power as lag free as a std T3 if not better but with the power of my current T34 with .48 ex housing, If i change the ex housing to a .63 I know I could see 400+bhp from the same unit SO;
spec;
2wd YB engine
Std compression
4x803 green injectors
4x4 I/cooler

I Want a turbo with less lag than standard, that will give me a good 350 lagless bhp, with the option of changing the ex housing for a larger one perhaps when/if I go lower compression ratio, any ideas?

I have heard good things of GT series turbos, I would go external wastegate too if that helps too?

Ideas on a postcard, names of people to speak to ( I think I already know this will involve Brummies )
