Ok i'm looking for a LS motor and well someone is selling me one for cheap 600 to be exact with everything a B18a. But i was wondering the difference between a B18a and B18b i kno the yrs are different and the tranny and maybe the OBD status. But would it make a difference i have a 98 honda civic DX HB and was very intrested in this swap. also would it be the same juss extending wire and IVAC that has to be moded. Need help very confused
