Just read the pm I sent you...it has everything you will need. Only thing I left out is since you are going from d to b you will need new mounts/halfshaft/axles. Also, the distributor will be obd2 on the b20 when you get it and you will need to source an obd1 distributor (I can't remember if an obd1 ecu runs obd2 distributor fine with just a jumper harness) Can anyone clarify this?
