Hey guys,

I recently picked up a 1984 Toyota pickup 2wd. I am wondering if I have the older or newer style 22re engine. The 10th digit of the VIN is "E" which means the truck is a 1984. I believe significant changes were made to the 22r(e) between 84-85. The engine is fuel injected from the factory. Here is a picture of the VIN/model plate. How much more difficult is it going to be to source parts if it is the older style 22re? I'm going to order a timing chain kit and head gasket soon. Would the engine from my 1992 be a direct swap? Below is a picture of the VIN plate. Thanks for the help.

According to your VIN, your Truck was built in December of 1983, which would be the 1984 model year.

The new (late style) 22R and 22R-E engines debuted in 1985, which would make your 22R-E the early style. If you post a picture of the engine itself, we can confirm which engine you have.

It is more difficult sourcing parts for the early 22R-E than the later versions, but I have limited experience on the "early" 22Rs and don't really know the current availability of parts. Early and late 22R or 22R-E parts are NOT interchangeable as there were several changes made, as well as the "early" EFI system being analog and the late EFI system being digital. These "early" engines were used in other Toyota cars at the time, but are quite rare for these trucks. The vast majority of 1984 Trucks were carbureted.

A 1992 22R-E engine would not be a direct swap due to the fact that the EFI systems between "early" and "late" engine designs are completely different; all of the 1992 engine wiring harness and ECU as well as all of the 1992 sensors would be required to do the swap.

 

Thanks for the reply. Would I be able to swap the engine from my 92 and use the intake and injectors from my 84? That way I wouldn't have to swap all the electronics. Apparently the intake and injectors for the EFI's were the same from 83-88.

 

take the 84 sensors and manifolds and put them on the 92 long block.. Same same...

If you have factory EFI, you have a "laser" block (identify mark is the "UFO" for the turbo oil return)

The difference between early and later is all internal to the ECU, we are talking about "EFI" vs "TCCS" you find these references in Toyota lit, which happens sometime around 86. Without actually seeing the code (disassembled dump) odds are its just nomenclature really.

 

Here is a thread on IH8Mud that discusses the 1984 22R-E: https://forum.ih8mud.com/threads/que...h-22re.282391/

Does your engine look like the engine in that thread?




The 1984 22R-E does use the early (pre-1985), non-laser (turbo oil return port), block and also uses a vacuum advance system for the distributor, and does not use a knock sensor.

I have no experience with the "very early" EFI, so I don't know for sure if the intake manifolds are the same, but if they are, you should be able to just swap out the 1984 engine with the long block 1992 engine.

Out of curiosity, is there a problem with the 1984 22R-E? Why do you want to swap it? Just for parts availability?

 

Another thing to consider is that whatever is in the truck after near 35 years, may not match what the ID plate says. Many hands have touched it in that time.
