Hi i just recently bought a 1990 acura integra with a messed up transmission with about 190K miles auto b18a and just bought an 1992 acura integra B18A1 engine with auto transmission. and i just want to replace the whole engine because this one has 70,XXX miles on it. my question was is it possible to do this swap? and is there any ECU or anything that will need to be changed?, also is it diffrent if i bought a 1991 b18A1 engine instead?thankssss!
