The only thing you'll be able to replace it with (within reason) is the same motor. As stated above, the B20/21A's don't mount the same as any other Honda motor. They're the bastard B-series's.My 91 Prelude had a B21A1 engine in it & blew up. What engine can I use to replace it with? Since the 20b5 isn't that good what would you recommend?
I know of a black 90-91 with a B21A1 in it, and it's a manual, but i don't know where you're at. I honestly don't know what condition the motor or transmission is in. He said he's gonna junk the car. I was thinking about ganking the engine out of it, but I don't know if i can drop it in place of my B20A5. I'm in Mississippi. It's in a small wrecker yard in the town i work in. He's also got an 88-91 Civic hatch that i'm trying to scoop up. Someone abandoned it along the interstate, and he said he needs to apply for a salvaged title. I said, "Well you better get hot, because i wanna snap that thing up, QUICK!" It's just screaming for a built H22 with possible turbo or supercharger.Ok Thanks Guess I will just junk the car then as I cannot find a b21 engine anywhere. I've got the ground kit on it too. New clutch & new head & it's in very good shape. Not worth a thing wihout an engine for it.
