bought a z a couple months ago and would like to turbo charge it....i read a couple of threads about this and got some ideas about what i want from my car and what i would like to do...i found a guy selling a turbonetics t3/t4 turbocharger from his evo9, used it for six months than upgraded...was wondering if anybody thinks that wouldnt be good for my z...its an 03 with 46,xxx miles on it...advice about this??
