Nick said that the S3X cam wouldnt be a good daily driver cam and i asked him why he thought that. He never really answered it fully The build you see below is everything i currently have (except cam,heads, intercooler,TEP trans) i have the cash to buy them right this second but im holding off to right before i get home (for warranty reasons/Research). Ive been looking for a few answers on a few grandprix forums that i havent found yet. this is the build i currently have going on.
