I got a 1996 2.2 and I was wanting to put it in my 1993 racecar. I can see that really all I can use from the 96 is the block and head and I will have to bolt all my old car stuff on (intake manifold, water outlet, alternator, coil packs, motor mounts, crank sensor) but aside from the actual parts, will everything work with the electronics?

I don't think you'll need to swap the lower half of the intake. I didn't need to when I installed the 95 engine in my 93.

The electronics are compatible. Use the injector harness from the 92. I don't know if you should swap the coil packs. Check the part numbers between the two year cars. The timing notches on the crankshaft were moved (maybe after 96) but the coil pack may have to stick with the crank.

I used the 95 style alternator bracket. The belt tensioner is maybe $30 for that engine, vs $60 - $80 for the older engine, and I knew I'd be replacing it eventually. I had to make some modifications to run the larger 93 exhaust manifold, including a little cutting, welding, and bending. Nothing too difficult, only time consuming. The thermostat housing is different for the older engine, but I believe the newer one works fine. The water inlet (behind the water pump) is slightly different, with the heater hose and radiator hose locations being swapped. Use the older inlet for best results. Also note that the heater hose fitting in head is different in the newer block. You'll need the older part here, too.

Since you're racing, I'd recommend installing a stock 93 oil pump before installing the engine. It's cheap, and it's higher volume than the newer pump. The pickup tube has to be replaced also.

I'f you can get an ecm from an S10 or other vehicle, you might find the timing is a little more agressive. If you can find a 2.2 with a factory knock sensor, that's the ecm to try. The 92 and 93 Cav engines used really mild tuning.

That's all I can think of right now.

The coil packs should be the same. I ran a complete 95 engine off my 94 ECM, no problem, but the sequential FI showed up in 96. I would assume that if the part numbers for the ICMs are the same, it should run fine. If you were to just bolt the 93 ignition system and injection system to the 96 block, it will work, since the only real difference is the timing marks on the crank.

I never considered the newer alternator/tensioner setup. I guess I can look into that, since I have one here to play with.

I'm not sure what the difference in the water outlets/ heater hose outlets is. I have a 95 spec engine in my car, and everything was the same as the 94 (except the CTS was in a different spot). Are you saying the 93 stuff is different?

On the 93s the thermostat is at the top verses the newer motors have it at the water pump. The 93s have a vacuum egr instead of electronic. The 1996 motor that I have had a completly different set up for the belts and tensioners so I used my old one. Now with the coil packs the ignition module is different: the old cars have 3 plugs on the module instead of 2 so I put my ignition module on the plate that matched the 96 block and used those coil packs. Everything worked out ok. The car runs good. I was a little worried but it turned out ok.

Thanks

Glad to hear everything worked out.

92 and 93 engines are the same. 94 and 95 are the same. 96 is the same as 94-05 internally, but have external changes.

The thermostat is on the top in the 92 - 95 cars. The EGR passage and the coolant passage to the heater hose connection are swapped. There are actually different gaskets for the two engines. The 93 housing is pictured here.

I used the 95 coil pack after the swap with no problems, but I couldn't be sure of the 96 compatibility.

Here's the 95 alternator bracket:
