Just bought an 89 hatch with a b18b automatic swap. OBD1. It seems like nothing else was done to the car in fact the guy tried to swap an auto tranny in it and failed. So its unfinished. I'm swapping to a B18a with a 5speed cable tranny. I'm just gonna run the motor stock with just an intake and exhaust. Should i change anything else? like the fuel pump? New to the Honda scene.
