so i have a 1993 Toyota p/u 4x4 it has a 22re in it now i spun a rod bearing however and picked up an 89 22re with 80k for $200 so i am going to swap motors and then rebuild the my original motor latter. i am kinda thrown off tho the motor i purchased says 22re on the valve cover but had a vacuum advance on the distributor and no knock sensor. does anyone have any clue on this? also i wanted to know how to put a knock sensor in and weather or not i could use the vacuum advanced distributor for the efi setup? all input will be appreciated.

 

Your motors are different years. They changed designs ect. You may want to buy an 89' 22re wiring harness/computer. Had a buddy hook up a 86' 22re to a 1991 truck that was originally a 22re, and it wouldn't run right and was missing some different connecters, ect. Instead of going through the whole engine he bought a wiring harness and computer off ebay. Hooked them up and it ran fine. Also my brother blew his eclipse engine, paid $900 for a used one, we put it in and it only ran on 2 cylinders but before we figured out that it was the computer he paid $780 to a mechanic to look it over and check every thing. Just better to get the same year computer/wiring harness with the engine.

 

as daniel said different years different designs, the older 22re didnt have a knock sensor but used the dizzy as a sensor.
