I currently have two pickups with 22re motors. One is a 1987 22re with a automatic trans. Its currenly running but needs rebuilt. The body is rough. The other truck is a 90 22re with a manual trans. The motor is currently removed and mostly disassembled. I bought the truck off a guy who only wanted $100 for it so I couldn't resist. The entire truck is in excellent condition. No rust what so ever. So my idea is once I pull the motor out of the 87 and rebuild it, I was going to put it in my 90. My question is what troubles could I run into with the swap. Electrical, ignition, etc. Thanks.

 

Well if you put the fresh long block into the newer trucks using the engine harness for the newer truck you should be good

All the electronics come from the truck the long block is going in Injectors all the sensors

 

That would definitely be the easiest way but I'd like to keep the original harness with the 87 for selling purposes.

 

You could rebuild the engine (long block) from the 1987 truck and just install the long block into the 1990 Truck, keeping all the electrical components (injectors, sensors, wiring harnesses, ECU, etc.) with the 1990 truck. Both engines in long block form should be the same.

You would then bolt up the intake manifold/plenum, and exhaust manifold from the 1990 truck to the rebuilt 1987 engine.

Then you would install all of the 1990's injectors and sensors to the rebuilt engine.

Basically, the only thing that you would need to swap over from the 1987 truck to the 1990 truck is just the long block engine, keeping everything else in place.

 

I just said the same thing in fewer words I guess The OP did not understand.

 

^^ Yes!

I just figured by the OP's response that they were not sure what you meant.

 

Thanks for the responses guys. Hopefully I can find all the sensors (the wire harness looks like a rat nest). Ill probably just buy new injectors since I'm rebuilding the motor anyway.
