Currently running a full stock LS in my 93 SI. I have a full b16A2 engine and a GSR head. Not too sure on building differences, as what I know b16 has higher revs, but i'm trying to figure out what's the best route for boost. Trying to make above 300 hp, maybe 350-400. Money isnt a problem, i know GSR is $ and that's fine. All in all, my question is a built b16A2 boost, or a built LSVtec(GSR head) boost.

 

Gsr is always better
