ok as soon as hasport will send me my mounts and stuff like that im going to have a b-16a in my crx and after a while I plan on putting as much b-18c5 internals into it so I was wondering what all will fit? I know the intake manifold will fit and cams and all that good stuff for the head but what about the pistons? if I am correct I can use the pistons but not the rods? I just want to know I will be able to faster with out a turbo or supercharger or especially nitrous.

thanks

 

You can use anything and everything from the head. No problem with that. I'd actually stay away from using components from the block. Using R pistons will actually lower your compression. The rods would be to long I'm thinking also.
You'd start hitting stuff.
