Awesome 4runner! I have an 88 that's almost identical to your's. Mine's automatic, 3.0 V6 with almost 300k miles on it. Still running "well" but it's due for some major work so I'm looking at my options.
Your thread particularly peaked my interest with your 3.4 swap and your mention of a camper build for it. I'm in the info gathering phase of a 3.4 swap. I'm also toying with different build ideas for camping. I was wondering how your swap is going and what camper ideas your toying with? My ambitious side likes a mash up of miniorf's Tacoma camper build and stormnmormn's 88 4runner rear shell modification. In reality my ambitious side may lose out to my lack of skill lol.
Here it is the day I picked it up in Portland, April 2014. Drove it home to Toronto without a problem. Currently residing in my garage for the winter.

That looks like a super clean 88. Nice find!
As for the swap I would start by reading this thread.
https://www.yotatech.com/f160/3-4-swap-101-a-239002/ From there just start searching yotatech every time you run into an issue and chances are someone has documented the solution. The most daunting part for me was definitely making the wiring harness. After reading a few tutorials and staring at wiring diagrams it starts to make sense. Let me know if you have any questions!
My camper plans continue to evolve. Currently I plan to remove the top and replace it with a forward hinge pop top. I keep wavering on the balancing having space in the camper while not trying to cram too much into a tight space.
As for my swap I'm about 95% of the way there. I drove it far enough to flush out a few issues. The main one being a high idle. I pulled my IAC valve and it was filthy as expected. It's supposed to allow coolant to pass through, but the inlet hose was full and the outlet was dry. Hopefully that's it.
Now - I have a serious problem with starting new project before finishing others. With my 4Runner out of the garage for the first time since buying my house I got really excited about the potential to insulate the walls to make winter wrenching a bit more comfortable. That led to sheet rocking the walls...I was going to save the ceiling for later, but I knew "later" would soon become "never"...so i cleaned out the rafters, re-did some wiring for my shop lights, insulated the ceiling, and hung the sheet rock. Just need to tape and paint the ceiling before I pull el Burro back in and finish up the swap so I can start in on the camper. It's been a two week detour, but I can't wait to work in the clean, bright, re-organized space!
Cheers to 80's Toyotas!
