I am preparing to make the same swap on another member's car. The real issue is the flywheel. You must use the s2 flywheel and distributor because of the crank sensor. Its a good idea to take pictures of both cars before starting, and don't let the various fuel and electrical parts get mixed. Most of the major parts are the same.

A similar question was brought up just recently - http://www.924board.org/viewtopic.php?t=18078

I'd give you the same answer even though you have a complete 931 wire harness available - unless there's a big difference in condition between the 924NA and 931 wiring, I'd leave them where they are and just add the few extra wires needed for the ignition and the different wiring for the alternator and starter to the 924NA body. -Or just remove the applicable specific wiring from the 931 for use in the NA.
