I agree it must have been done before but it's quite an open ended question. How far do you want to go? Are you thinking small turbo with little boost or huge monster turbo that'll need virtually every engine component changing? If you can be a bit more specific in what you are aiming for hopefully someone will chip in with the help/info you are after.

i was thinking about using a T25 turbo at about 7-8 psi boost i dont really want anything that is goin to make the car unreliable i just want to give it a bit of a kick up the arse lol.

really i am aiming for a moderate power gain i was going to look into using cosworth pistons but i am not sure yet if that can be done.

boost mad

as far as i no, not alot of ppl modify the twin cam to any major extent... im not saying that ppl havnt done it but it doesnt respond aswell to modificatios as other engines that could be used ie the pinto. i no this doesn realy help what u wanna do but i thought i would say incase u thought ppl were being disinerested etc. might be worth going on some siera owners club forums as u might have abit more luck

good luck and let us no if u find anything out




also u dont say weather it is the carbed or the injection version of the engine, as if it is the carbed engine then it will be harder to do than the injected engine

hth

its the carb engine but i am going to be changing it for the injection version soon..
