I put a gude camshaft into my 87 CRX si.. it made the thing slower than before. i figured it may be a timing issue so i advanced the timing a bit, put in an integra ecu , and put in some integra GSR injectors. It picked up 1/2 second on the time that the car used to run.. Still not what i expected considering the price of everything. the only thing that i noticed a big gain on, is when i used notrous oxide with the setup.. It made a pretty huge diff over the stock setup with nos.. i also liked the higher rev limiter.. I would reccomend porting the head if you are going to do any kind of camshaft upgrade.. that may have been the problem.

I miss my old 87 Rex
