I have completed the swap. I bought an L92 & 6l80e from the local junkyard. Was pulled from a 2007 Yukon Denali. Everything functions as it should. There have been no modifications to the interior of the rig that would indicate the change. Gauges work, trans shifts as it should (with sport/tow mode and tap shifting, etc). I’ve put about 5k miles on it since the swap and I’m now comfortable saying all the bugs have been worked out. This won't be a true step by step instruction guide but it should be pretty darn close if you take the above motor/trans from a 2007 Yukon Denali and put it into a ’94 LC.
I made some changes along the way that aren’t critical to the build. For example, I didn’t have room to put the York compressor back in (after pulling the 1FZFE) so I set up an electric compressor. I added a second fuel tank that I could change over to on the fly so the wiring for that was roughed in at the time of the swap. I also changed the brakes to hydroboost (huge improvement).
A couple of disclaimers... I leaned on my friends to make it happen. I couldn't have done it without them. Everything from making fuse block labels to rewiring the Toyota cruise control lever to run the GM cruise.
You’ll need some basic skills. I'm not a professional welder but can stick metal together. Don't know how a guy could do this swap without a little metal fabrication know how. The other thing we absolutely needed was the FSM with a vehicle EWD. I had the Toyota FSM and bought the GM one on ebay.
A couple of additional pieces of information… The Landcruiser had a 4” lift and with 35” tires prior to the swap. I had also regeared it from 4:10’s to 4:88’s. If I had known this swap was coming I would not have regeared it. Not necessary with the power I have now. Prior to the swap I was getting about 10mpg. I’m now at about 11mpg. At 70mph I’m just under 2200 rpm. Total cost of the swap was about 11K without any money going toward labor. For a shop to charge 30k for this job is not unreasonable. Probably pencils out to about $4 per hour. I started it in October 2020 and had it driveable by spring 2021. By October 2021 I finally had every last detail ironed out.
Finally, I feel a debt to the many who have gone before me and posted their build on this website. I couldn’t have done it without you. I’m not one who typically posts stuff so I’m sorry in advance if I screw up the posts. The posts will come in pieces. We’ll start with prepping for the swap…
