From some one who converted a NA car to turbo, its freaking pain. IT takes alot of time & money.
Id only do it if you were trying to double your engines out put.. NOS is alot cheaper. and easier.
I had a premade turbo kit, there were computer programers out and i could have about everything i needed, as long as i had the cash.
things to ask your selfHow much boost can the engine take before i have to change it.
drive train
fuel system?
computer. (im finding out im not to far away on what my MAF can generate in frequency. fast systems are $$)
on a good note, i guess, i saw a guy at the track who converted his caviler into a turbo cav. guess he got into the engine to make it handle boost. He was running flat 13's. To me though its not worth that much work to get 13's.
