stock 440s will get very close to 350hp, so probably not worth upgrading. FMIC is a must have IMHO, although STI 8 TMIC isn't too bad. 16g or 18g good choices of turbo, VF34 can work but the actuator is often a limiting factor. However I've seen 16g struggle to make 320hp yet a VF35 make 360hp so the base car can have a big impact.

What sort of IDC - presumably the 'required' max. of 98%, and no more?

I take it under 'normal' circumstances, correct mods, etc., then the 16g IS capable of upto 350bhp, though?

Another vote for the 18g - it'll defo get you over 350, assuming all the appropriate supp. mods., good mapper, etc.

BTW, D4VEW557, a 1997 STi is fitted with a VF23, but it's only good for about 320-odd max, I think(?)
