EJ22

Differences Between 1992? and 1995

• Wiring harness on opposing sides of the intake
• PCV valve height lower on older EJ22
• Crankshaft/Camshaft position sensor harnesses are a wire whip on older, more compact onboard-connector on newer.
• AC Compressor form factor and bracket very different between older and newer
• 1995 uses EGR, 1992 does not.

Swapping 1995 EJ22 engine for 1992

• Re-use the intake from the 1995, noting differences list from above
• EGR valve from newer intake won't work, plug / eliminate it. Hope for no CEL codes.

What not to do

• When removing engine but not transmission from an auto, use access-cover plate to remove torque converter bolts; leave torque converter on the transmission.
• If you do end up being a dumbass (like I was) and removing it with the engine, do the following:

1. Pray.
2. Remove outer-shaft from transmission input, keeping sprung clip intact -- note the keyway in the torque converter that has a "T" in one side; compress clip and slide the outer-shaft into torque converter until clip seats firmly. Shaft will not be very secure.
3. Look into transmission input to find the two (very) internal 'keys' and make visual note of their position.
4. Slide torque converter and shaft assembly back onto transmission input and wiggle until seated firmly. Now you have another 1/4" or so to go. This is where the visual note comes into play, as you have to line up the keyway with the keys in the transmission until back of tabs are visually flush with the bellhousing. Good luck, this part sucks.
5. If you do not have the torque converter assembly installed correctly, take a break and try again later. It is IMPERATIVE that this be done properly, or when you mate the engine to the transmission you will hear a "THUNK" sound, and you can now begin looking for a transmission shop or new transmission, and probably a garage that will do this all for you. Your transmission cooling pump just snapped off and you'll have to do a significant amount more work to fix this.
