3.4 Swap Questions (1 Viewer)

About to finally get the 3.4 swap underway on our 1990 4Runner and am going to have a buddy of mine pull the old engine for us since he wants to keep it for himself.

What parts do we need from the original engine? So far I've got:

-All accessories & brackets
-Oil pan
-Main wiring harness (have conversion harness from ToyOnly Swaps)
-All exhaust (have crossover from Toy Only Swaps)
-Starter
-All fuel lines

I think that's about all of it right? We've got a new clutch kit so don't really need the flywheel or anything.

Let me know if I'm missing anything.

Thanks!

you need the 3.0 motor mounts.
the 3.4 alternator plug. and starter lead.
if you aren't playing the smog game i recommend that you don't relocate your battery.
you likely will need to update your ps pump. the rack pumps dont tolerate big tires well.

you also need the oil pressure sending unit from the 3.0. it needs to be swapped with the 3.4 switch if you have an oil pressure gauge.

I used all the 3.4 emissions stuff from the donor but I was going from a 22RE. What fan are you going to use? the 3.4 is a lot bigger than the 3.0. What air box?
