[Toyota4x4v6]

So i thought i would document my swap, i know there are plenty of other swaps out there, but i figure more swaps, more info for every one else who wants to do it.

So several months ago i drove to Canada and picked up a 3.4 from a 1998 Toyota 4Runner 4x4 Auto. To put into my 1991 Toyota Pickup 4x4 5 Spd
The guy i bought it from through a R150F transmission in for free, along with some other parts and a box a Toyota bolts.

First off, i flipped it over and pulled off the old oil pan. scraped off the old FIPG.
Then i modified the oil Baffle to clear the 3.0 pickup tube, by grinding several areas around the edges and cutting a hole in the center, Before i put it back in i took it to the sand blaster and cleaned it up real good. The 3.0 pickup tube bolted up nicely to the block with no problems. You can easily see the difference between the 3.0 and 3.4 pickup tubes.

Then drove new oil dip stick union in and applied a layer of Toyota FIPG around the mating surface and put a 3.0 Oil pan on.

Right on :smokin:

New Water pump and timing belt

Then cut up and MIG welded the cross over pipe back together so it would come out on the drivers side. Using this guys instructions. Build your own 3.4 crossover pipe - YotaTech Forums
Then wrapped it in some heat wrap.

So then i pulled the old 3.0 and later pulled the tranny because i figured it would be easy to put them in together.

 

[Toyota4x4v6]

So then i cleaned up the tranny
stripped the wiring harness out of the 3.0 and pulled the gauge cluster out and sent it off to Toyonlyswaps
I also bought a High pressure fuel line extension, High pressure power steering hose and battery tray from Off Road Solutions

 

[Toyota4x4v6]

New 3.4 Flywheel and clutch
Then mated the tranny to the 3.4
Bolted on the cross over pipe with new gaskets
And dropped it in

So since the fuse box is on the passengers side and the battery is on the right the main power source needs to be extended. So i went to Mclendons and bought about 6 or 7ft of 8 Gauge wire. (cant remember how long). Then wired it back to the positive battery terminal. Using this guys instructions 3.4 Swap 101 - YotaTech Forums

That engine is sitting mighty low. Do you have body lift, or did you do something with the mounts?

 

[TatonkaII]

Lookin' good! Admittedly, I do NOT miss doing this swap.

 

[Toyota4x4v6]

ya there is a 3 inch body lift, worked out pretty good though

 

[Toyota4x4v6]

Well I bet going from the 4 cylinder added a whole bunch of details i didn't have to deal with

 

[dntsdad]

Just some advise.......take the heat wrap off and try to affix the stock heat shield that was on there. Many, many reports of the heat wrap causing heat buildup and therefore cracks and breaks. Also, water and moisture retention causes rusting.

Also, curious why my had to send the gauge cluster to the wiring company? Are they simply soldering the resistor on the tach for you?

 

[Toyota4x4v6]

Well i was going to use the old heat shield but i mangled it pretty good getting it off, and the heat wrap i put on isn't on there super tight either so im not too worried about alot of heat build up. For the gauge cluster i was going to solder the resistor on my self but then the guy from toyonlyswaps told me it would cost the same regardless of if they soldered it or i did. So i just figured i might as well let them do it, since its just one less thing i needed to worry about.
