Hello fellow yota lovers! I am replacing my wornout 22re in my 87 pickup. I have a 91 22re that I want to swap in. How much of a pain in the but will it be as far as different vacuum lines, wires, sensors, etc? Is there any special thing I need to do or watch out for?

Thanks!

 

It is very possible. However, if you use the 91 motor then you need to change the sensors over from the 87. That way you can use your stock ECU and harness.

I have a 93 22re in my 87. Everything swaps over just use the sensors and possibly the entire intake manifold from the 87. My manifold had a couple different vacuum lines on the 87 vs. 93. I also had to change over the distributor, as they wiring was different. Everything works fine.

 

I suggest doing a refresh on the old gaskets. Just get a master gasket set and a timing chain kit and have fun

Doing this means you wont have to rip it back apart in case anything happens.

 

The 87 and 91 "engines", meaning block and head (with the exception of the turbo models) are exactly the same, bolt for bolt, except 2wd engines have a different oil pump pickup and oil pan than the 4wd engines have. The 91 has some emissions changes and such when compared to the 87 but those are "year" specific, not "engine" specific. The 87 has a slightly different intake, throttle body and vacuum hose routing than the 91, for example.

The 87 intake will bolt up to the 91 engine; the 87 exhaust will bolt up to the 91 engine. Pull everything off the 87 and pull everything off the 91. Then put the 87 things on to the 91 engine and you'll be fine. Either engine bolts up to any transmission from any year the 22re was available.

What Bassmastry101 suggested is good advise. Timing chains should be replaced at 80k-100k miles. Valve cover gaskets will seep after a while. Replace the front and rear main oil seals- they will leak eventually. Better to do it now, while you have things disassembled than to have to take it apart later.
