Hey guys trying to find out if a f18b cpu, wireloom and transmission is compatible with a f20b engine??

F18B is a SOHC VTEC engine, the F22B1s destroked little brother.
F20B can be one of two engines,
SOHC shorter stroke variant of the F22B2 group. Non-VTEC
DOHC VTEC baby brother to the H22VTEC engine.

I doubt the harness would fit properly and the ECU might get the engine running, but it will be out of tune.

Probably need a chipped p28 at least for a DOHC F20B. That's what I have. The F20B (manual) came with a T2T4 LSD. Not sure what the F20B auto tranny is however. Aradin or MadMike sure know a lot more.
F20B (DOHC) is a destroked H22 btw.
