Hi all, We have a JDM SiR II 1993 EG hatch fitted with a B16a2 by Honda Japan. I'm thinking about changing the bottom end for that of a B20 and mating it to the B16a2's head. Does anyone know what will be needed to do this? Will the car's standard P30 ecu, driveshafts and tranny all be ok? Do we need to change anything, or will the head just bolt straight on??
