Hi:
I did the reverse of what you are doing 2 years ago. I put a 1992 engine into an 1986. There were some differences due to the ignition change from 2.2 to 2.4. I had to use the distributor, intake manifold and injectors from the 86. I also used the 1986 Garrett Turbo. Because I didn't want to change out the hoses for the Mitsubishi unit. You will have these problems in reverse order.
I did alot of research at the time and found out the 1986 230FT was the 2nd generation turbo engine after the B23. They called this a lower friction engine. With smaller connecting rods, rod bearings and piston skirts. It was a good engine but was the weakest of the bunch. Subsequent modifications in 1988 and 1994 corrected these problems. It was the only version to use shims at #3 main bearing to control thrust. All other versions used an integral thrust bearing on #5 main bearing. My shims fell out causing massive end play and destroying the engine.
Before installing that engine, I would pull the pan and check bearing clearances and crankshaft end play. If you don't want to pull the pan, at least, check the end play. I would also replace all the seals. This might save you alot of grief later on.
The ZF4HP22 Tranny was used on the non turbo and diesel cars for 1986. The turbos used an AW tranny. If it's a ZF, I wouldn't use it if you have a good working AW. The ZF is known to burn up the front clutch pack. If it's revved up in neutral or park. Good rebuilds haved fixed that problem but yours might not be rebuilt.
Good Luck.
