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...
