I have an H22a4 swapped civic, and due to problems with the engine, I recently bought an F20B Vtec to replace it. I know that I have to take the alternator, vtec solenoids, crank pulley, intake manifold, fuel rail, injectors, and oil pump from the H22a4 inorder to run the F20B on the H22a4 ecu. Any tips on how to rewire it OBD2a?
