If you have a donor 16 valve, it will make the job much easier, since you'll
need the ECU and wire harness from the 16 valve engine, the radiator, and
will have to block off the SLS rear suspension pump. The fuel pump relay is
different and the 16 valve used dual fuel pumps which the 2.3 didn't use
until '88. The 16 valve also had the ASD limited slip differential, so that
would be nice to have with the swap.
