GSSR: Well wouldn't the intake manifold, gasket, and cams run with a turbo? If you are planning on selling some of it, let me know. I can't guarantee I'll buy it, but I'd definitely consider it. Esp. the intake manifold and cams.
Questions though, would a set of stage 2 cams be better? I know I'd need to upgrade my valve train, but wouldn't I realize more power?
Also, I thought that there were legal turbos for our cars like Greddy... I live in Ontario, and I'd need to check the laws. Being smog legal is probably most important, Ontario (Toronto) is becoming strict, probably getting close to Cali strict.
Thanks for the help so far.

N/A cams will not work for turbo because of excessive overlap and duration causing the boost pressure to blow through the cylinders and right out the exhaust manifold before it has a chance to burn. If you are iching to upgrade your cams and valvetrain, ITR cams with adjustable cam gears and ITR springs would be a good choice for both turbo and N/A assuming they are tuned right. The valvetrain wouldn't matter between the two routes, but overly stiff springs will create unnecessary friction and wear while sucking power.
The intake manifold is probably a good idea to eliminate any bottlenecking before and after a turbocharged engine, but not entirely necessary.
You can upgrade to stage 2 cams, but you can kiss the turbo route goodbye as they will not be suited at all for turbo.
