I have a 95 prelude, ive found a f23 single cam for cheap....its just to have it driving. Will it bolt up to the mounts? also what about the F20 ive also found a cheaper one of those. I have a p12 and p13 ecu, im pretty sure the p12 would run the f20, but just curious. Ive swapped h series motors, but wondering about the f23 and f20 as far as mounts go, any help is appreciated thanks.

 

On both of those engines you can reuse your original prelude mounts. I know the f20b has a different drivers side mount.

 

I'm running an f20b on a p13, but with h22 intake manifold and injectors.

 

It's really a toss-up, the F23A has more torque but is obd2. You could use a 94-95 Accord EX ecu for the F22B1, it would be pretty close. The F20A could potentially run H23 & F22A ecu's also, you just need the corresponding injectors. The downside is both probably have lower redlines than the F20A wants.
