Okay I heard else where that you can bolt up a greddy turbo kit for the D16Y8 or the JR Supercharger for the D16Y8 to a D16Y5? Physically I know it should bolt up, but will I need to do anything fuel system wise since my engine is lean burn? The main goal is to have a street legal, smoggable, D16Y5. All help appreciated.

 

bump for some new info...

 

Pull the roller rockers out, and go find a D16y8 (I believe that's it) to put them in then boost that. IMO

 

Can i just drop those roller rockers in? At this point i was thinking of just boosting the Y5...
