There's a guy here selling a 90 Integra, who said there's only "minor work" left in regards to getting the car running. The body/interior are supposed to be in good shape with no work needed there. He put in a B18B into it, and converted to OBD1. Now, I know nothing of all these Honda engine terms. From my research, it looks like a B18B should be a direct bolton (Minus the OBD1) with no aftermarket stuff needed? The guy's asking $600 Canadian for the entire thing - shouldn't a decent B18B alone be worth 400-600??? If the OBD1 wiring is all complete, would it be a relatively easy swap to do?
