Do a B series swap. B16 cable actuated. around 2 G's for all the parts. Go to jspecjdm.net for a full swap(even the motor mounts). Another swap is the ZC whic is a direct drop in to any 88-91 CRX. You can use the same motor mounts, headers, and intake manifold, etc. A lot cheaper swap but not as many parts on the market as the B16.

 

um, i'm pretty sure everyone here already knows all that?
