Looking for a good picture of the location the dip stick tube goes into the block....
Here's a great write up on the oil pan and dipstick change process... This should be all you need:
http://chat.4wheelunderground.com/index.php?topic=140.0Don't screw up (like I almost did today) and think that the T100 pan will clear on an IFS truck (1st generation).
Apparently the pan has to be further modified to clear the diff if you're IFS. Chilkatdesigns can apparently do this for you (waiting on a quote) or you can mate the 22RE pan (cut it away) to the 3RZ mounting surface.. Assuming you're a decent MIG welder.
Sending units:Thanks.. I'll plan on swapping the oil pressure and coolant temperature from the 22RE.
AC: Solution 1:In messing with the 22RE and 22RTE, there are definitely at least two different compressor types and two different mounting systems. As my 4runner is 1988, I assume I've got one of the later ones that will work. I'm being told that the 22RE compressor setup will mount to the 2rz/3rz with 3 out of 4 holes (good enough) and to get it to work with the 4-rib belt system, you simply swap the AC clutch from a 1st generation MR2 (4AGE). I've never seen a photo or documentation of this change. This is what I'm planning on doing, I pull the 22RE without the AC compressor - AC works great currently and I won't have to deal with re-charging the system.
Solution 2: Have custom hoses built that adapt the 2RZ compressor to the truck. New o-rings for 134a.
Solution 3:I'm told that swapping in the 1988 3.0L AC manifold to 2RZ, this will work with the existing AC hoses.
Tach:
Solution 1:Thanks for confirming! I've read about the tach mod - or using a potentiometer instead of a resistor to tune it. Megasquirt should be the same as the 2RZ ECU, assuming they both send a "standard" tach pulse. The 22RE tach is oddball, I think it's variable voltage. Here is documentation of the mod:
