Yeah, any B series motor will be a strait forward swap. The most popular motors will be the LS (B18B), the B16A's, and the GSR's (B18C1). Which one you choose depends on how much you have to spend and how fast you want to go :thumbup:

Or you could build up a CRV motor (B20b/z) and slap on a VTEC head for a nice torquey monster
