Skimask, welcome to H/A. Now is your CRX a Si. For the swap alot of guys like the B16A,Aem short ram intake, if you live with alot of bad weather snow etc. I'd get a Thermal Research Development exhaust which is stainless steel throughout. I have one on my Civic Si. Cams & Valves go with the CTR or Skunk2. Of what I mentioned you'll be looking at least 6K.

One thing keep in mind the B16 have no torque. Another thing alot of guys go with if properly done right is get a B18A LS block & put a B16 head on as a LS Vtec. Do more research. Good luck..
My self have a B16. It doesn't have the torque but I don't care. When I want more torque I just jump in my Integra Gsr .
