i had one on my b-16 with a stock throttle body. and walked a gsr twice. this manifold will work best on built n\a 1.8's or 2.0 motors. not saying itwon't work but you would not get the full potential of it from a small b-16. this manifold makes its power from 7k up so if you have not built your head\motor to surpass a 8k redline it will not be you best buy. b-16 power starts to fall off at 7400 or 7500 rpms. honestly when i put this on my b-16 i felt my low end was compromised. and the reason i put on the stock throttle body is because the place i ordered it from sent me one for a gsr. if you plan on putting a 1.8 block in later if the deal is good enough you can get it but studies show that the performer x is a little bit better than the victor. also what shell will this be going in? cause in some shells some modding might have to occur. good luck.
