honda 2.2 = accord? or prelude? or what?
you're gonna need the motor, and the ecu for that motor
if you run a P13 (h22 obd1) then you'll need a conversion harness to run the obd1 ecu in your car, and the motor will need to be all obd1 electronics
if you've got an f22 then you can use your stock trans on the cheap, but it would be better to get an h22 trans, and even better to get one with LSD
