I am doing a low comp b20b swap from a 96 smx. From what I've read everything is practically identical except I do know that I have to change my b18b1 crank pulley and intake manifold over and sensors, I'm running for management a LS p75 obd1 ecu, do i need to swap the oil pump from the LS to the b20b? And all the gaskets and belts from a b18b1 should be able to go onto the b20? Any info would be nice.

 

They don't have the smx I'm America, so I don't think your going to get answers regarding it. I just had to search what a smx was

 

That is just gong to be a regular JDM B20, doesnt matter much what it came out of. You can use a honda website and look up parts from a 1996 CRV or Acura website and look up part numbers for a 1996 Integra and check to see if they cross. But I am about 90% sure they are the same as far as manifolds go. HG is differently obviously for the larger displacement.

 

swap intake manifold, and crank. I usually keep the original crank with the engine and just by the utility belts differently, yeah its a hassle.
