If your swapping into a '92-'95, all you basically need is the motor, valve cover to oil pan, preferably with the intake manifold and distributor (I'm guessing they're all the same, but I don't know for sure) and the correct ECU. You can re-use any D-series tranny, axles, shift linkage, clutch and flywheel. It's worthwhile to budget in a D16Z6 tranny if you can, since the more aggresive gear ratios will help out a lot.
