Street purposes might be better to go with the turbo or SC. Couple different types of SC's. f you are set with going SC then the exhaust stuff should be good (hi-flow cat, cat back exhaust). Sometimes the intake path is chaged, & you will have to adjust the A/F Ratio & Timing (ala CZ might go away).

Or if you are more technically inclined you can rig up your own homebrew system with a gt35 turbo if you want to make real power ;)

Will take some research and access to someone with welding skills...

What we need is someone to sell the exhaust manifold only... That'd be a nice addition to our aftermarket...
