T100 as donor for 3.4 swap

I have a 92 Toyota p/u 22re, this is one of the rare times I've wished I just had the 3.0... Anyway I also have a t100 with a 3.4 as a donor for the swap. What I am wondering is as far as the oil pan and other needed items can I use the one from the t100 or do I need the 3.0 pan. I haven't picked the t100 up yet but just out of curiosity due to the fact that the t100 I have seen are just wider versions of my truck. Does using a t100 make any aspect of this swap smoother?

Thanks

I used a 95 T100 for my swap as well and, yes, you can just use the oil pan and pickup that is already on the T100 3.4 motor as you swap it into your pickup.

Also, using a T100 motor makes it so you don't have to relocate the dipstick. The other things that might make it easier for us to tell you if a T100 motor would be easier is more details on each rig. 5 Spd to 5 Spd? Auto to 5 Spd?

the t100 is an auto. my 92 p/u is a 5sp. Both are 4wd. I am glad about the dipstick step being taken out that what i figured when using the t100. Part of me would love to have the auto from the t100. However it is a column shift. i was thinking of maybe getting a floor shifter from a tacoma to use in my truck. Ive been reading non stop on these swaps and i think i have most of it down but now it comes down to.

Fuel lines.. will the ones from my motor work along with my fuel pump.

ac.. kinda a must and both trucks have ac but i would prefer not to discharge my system if at all possible.

and power steering pump.. havnt researched this area yet

thanks!

i am in Lincoln and auburn north of Sacramento a bit. I will keep that in mind i will probably have quite a few parts for sale after this swap.

another question i plan to use all the emission stuff from the t100, from what i understand in CA as long as the vehicle is newer and the same class this can be refereed and continue to pass smog?

The wiring harness is longer so the ecu fit wont be so tight.

Ok something I was wondering the t100 has a column shift for the auto. What are my options for this? Can I use the column set up in my truck? Get one out of another auto my year? Or can I use the floor auto shift out of say a Tacoma?

Ok, the power steering pump will probably have to be the 3.4's. If the RE in the 92 is the same as the one on my '83 R, then the pump is on the wrong side of the engine. Not for sure on that one, but I bet the 3.4 would be better anyway. Check the lines, they may be long enough from the T100 to fit, not sure. As for the ac, which side of the engine is the compressor? If it's pass side, maybe a pulley swap and fabricated bracket will do the trick.

good deal man im getting my donor truck soon so i want to start laying out all of the parts. The question i really have is the transmission. What are my options in this department? can my 5sp work with the 3.4?(based on can the tranny handle the power, what adapters will i need? can the ecu from the t100 work with a 5sp.) or if i use the auto from the t100 can i make that auto tranny a floor shifter.

thanks to all who have replied!

Most of these have been mentioned, but here is a direct copy from post 103 from my swap thread.

Notes on using 4WD T100 as donor
Thought I would document some notes about using a 4WD T-100 as a donor vs, Taco or 4Runner.

My donor was a '97 4WD T-100 xtra cab, but I would imagine that all this holds true for any of the 4WD T-100's with the 5VZ.

1. If you are running IFS you don't have to do anything oil pan/dipstick related to the donor motor. This saves you all the oil pan swapping and dipstick relocation stuff. Which is especially nice if you were dreading the block drilling that sometimes has to be done.

2. The wiring pigtail for the EVAP stuff (and ADD) is part of the body harness and not the engine harness. You will need to cut the "pigtails" off the harness right where it passes through the firewall. Then it can be respliced into the engine harness via the two connector plugs that are part of the engine harness. It's easy since the wires are all the same and colors match right up.

3. The T-100 uses a steering gear box and not rack and pinion. Therefore the power steering high pressure line has the correct ends on it to retain the P/S idle-up feature. This one I cannot confirm for sure as my donor's HP hose was very rotten, and I didn't want to risk running it. It looks to be slightly long to be a direct fit, but it could easily be disassembled and mated to a new center section of the correct length at a hydraulic hose specialist. Also note my donor was non-ABS.

4. Since the T-100 is larger and has the ECM located in the passenger side kick panel, the engine harness is longer than that of tacos or 4runners. This allows for proper mounting and orientation of the ECM with the connectors down. It also has a round firewall grommet that is only slightly larger than the 3.0's. and fits right in without modification. (Most of the 4runner and tacos I have seen have a squared grommet)

I kept my AC compressor. I'm doing a similar swap using 96 T100. You do have to swap the pulley from the T100.

you could just get a r150 or r150f trans out of a pickup (dont get years 92-94 because of the speed sensor is electronic not mechanical) or 4 runner and that'd solve your whole problem right there

I've got a 96 TWD SR5 that I'm using as a donor to build a 97 4x4 SR5. Is it possible to tie the T-case harness on the 97 4 wheel to the engine harness on the 96 engine harness?
