Hey whats up guys? I have a 91 integra and I want to know what motors I can just drop in. Specifically a 94 1.8L? Are there any other motors that will work?

 

Welcome to Honda-Tech. The search feature here is your friend, pay him a visit once in a while.

Regarding the 94, there are 2 different motors, the B18B1 which is pretty much functionally identical to your stock B18A1, and the B18C1 which utilizes VTEC and is a considerable bit more powerful. Both will bolt right in, however the B18C1 will require a different ECU and possibly an OBD-1 conversion (depending upon how exactly you want everything done).
