Seeing your door without speaker holes hacked in is a first for me. I have 3 sets of doors and all have been cut for speakers.

Chapter 16: The other Toyota
Now with the paint left to dry, it was time to pivot over to the pink elephant in the room, the other Toyota.
I was not looking for more Toyota’s, but a friend of mine sent me this ad and I couldn’t turn it down. It was a 1988 with 22RE manual. Somewhere in my vision of this Truggy build entered an idea of putting a turbo on it. I often pushed it back in the corner of my mind because I knew I would want EFI to make that happen. But I also knew that I would be way more pleased if a rock crawler had EFI in general. When this thing popped up as a non-runner but ran when parked and basically give me a really nice keg of beer for it, I couldn’t resist.
So here is a picture of the two together to give a point of reference for how long this has been lurking in the background.
Don’t feel bad for it, it had a completely rotten frame and was all used up. The engine, however, needed a happy fuel pump and was back off to the races! The thing ran really well! So, as I mulled along on the actual build when I was tired of working on that, I’d play with this one. You know, like how long of a burnout can a stock 22RE do? If you feel like you need that answer, I can already tell you, you’ll be disappointed.
Ok, so now what? I know the stock computer leaves a lot to be desired, it is robust and reliable, but not much to play with in terms of making more power. With that dare to dream of a turbo still echoing in the back of my brain, I caved on something I’ve been wanting to dive into on something for a very long time; I bought a Megasquirt PNP.
Up to this point, I had never dived into programmable logic in automotive applications but have in industrial applications. I felt confident that I could learn the ins and outs of this black magic. I knew right away I wanted to use this thing to its full potential and have as much control over the engine as I could. So soon after I plugged it in and had it running off base maps, I was cutting wires and hacking the harness up. Step one was the obvious, a wideband. I started with an LC2 from innovate. From there I set off to build a crank sensor reference.

Once that was built and useful, I moved on to the distributor. I wanted to turn that into a cam sensor and use GM coils to manage spark control.

Once I had the mad scientist stuff figured out to this point and had enough runtime to feel like I would actually be able to know what I was doing. We were ready to pull the drivetrain for the truggy’s repower.

Chapter 17: Triple Sticks
Now I don’t get to play with machinists’ equipment as often as I think I would like, but when I have a project that requires that type of work, I have a lot of fun with it. Now was one of those times. I decided to drop into the deep end and add an additional low range gearbox to the drivetrain while I had it all apart sitting in front of me. Yes, this would require yet another redesign of my transmission support, this was very disappointing to me, but things you run into when you are flying by the seat of your pants.
So first thing first, which is likely obvious, I had to cannibalize a t-case and build this using one of those fancy doubler kits. The kit was straight forward and had not drama. I opted to have some smarts and upgrade to a 23-spline input and output between the two low ranges.
Once I had a complete unit, I moved onto the fun part; figuring out how I was going to build my linkages. I decided to make a shift block for the rear t-case and use shift rods to stack the shifters side by side at the forward low range box. The shift block was the machinist part and was a lot of fun to build out. It’s not fun enough that I want to start pumping these out as a side hustle, but enjoyable. I began by just cutting out the basic shape of the block. I used two plates, because my idea was to sandwich needle bearings in this thing to attempt to keep the shifting smooth and reliable.

I cut the arms out by hand, which is why they look a little crude, but they do the trick.

Now that I had my shift block created, it was time to start building the linkage system out to the handles.

Chapter 18: Heart Transplant
With the trans and t-cases ready for fitment, it was time to drop those and the 22RE into the chassis. Unlike the last chapter, this chapter is very picture light and word heavy. Looking back on this, I never felt then, that I needed to take pictures because the progress made was small and tedious. However, there were a lot of small projects wrapped up.
I cleaned the engine up and threw a new rear main seal in, a new clutch that was a little more up to the task of clamping for boost later on, front crank seal, and valve cover gasket. I painted the block just to keep everything clean. I had decided to pull the intake plenum off to do this work. Basically, a craigslist rebuild.
Once I had the engine/trans/t-cases back in, I continued focusing on the wiring. Before reinstalling the intake plenum, I took the original engine harness apart and thinned it from the wires I would no longer need and tried to tidy everything up. These old Toyotas run the wiring loom without a firewall connector, and I knew I wanted to change that. So, I bought some Deutch flange connectors and mounted them in.
For switching from carbureted to EFI, I decided the easiest thing for me to do would be just to transplant the entire wiring harness from the ’88 truck I had, so I started down that route. That harness was very whole yet, so it was lucky to have that unmutilated. I opted to pull the entire dash out to do this. I'm glad I did, the amount of mouse feces I was able to pull out from the dash insulation was worth it. I ended up replacing the insulation all together with the bubble wrap stuff you can buy for houses at Menards. Once I had everything gutted and cleaned, I put the new insulation in, followed by hanging the EFI harness.
Getting all the wiring in place took some time, but wasn't very hard. Once I had the wiring sorted, I had to shift my focus to adding a fuel pump to the gas tank and routing feed/return lines for that. I used aluminum tubing from tank to engine bay and adapted over to flex line to the engine. I initially did this retaining the factory fuel regulator which worked well enough.
Once all the wiring was completed and the dash was back to being whole, it had come time to validate my work by starting the engine and ensuring everything transferred over ok from the '88 truck to the '87. It barked to life without any drama. A transplant success. Itching to drive this thing now, I needed to work to make it mobile again as at this point, I still had a jackstand under it to hold the trans up and no driveshafts made for the lengthened driveline.

Chapter 19: Belly Pan
I had a couple design consideration when rebuilding the transmission mount for the 3rd time. One of those considerations surrounded the rear quarter elliptical perches on the back and having noticed that even through I had reinforced that area substantially, I had a portion between the front and rear suspension points that was just the 3” C-channel, and that area showed some deflection from the force applied as twist to the back bulkhead the elliptical mounts were mounted to.
Another consideration was the levearage the lower link mounts might have on deflecting the frame in the future. So, considering these, I opted to create a sort of sub frame much like how you see any modern rock buggy get designed. Then I figured, after I had that made, I could just bolt the belly pan to those. So what I did was fabbed some flatstock to bolt up vertically that I would later weld to the belly pan. This would allow me to not have any bolt heads showing on the bottom of the pan.
So, I decided to use more 3” C-channel, (you know, the free stuff), and weld that to the front and rear lower link mounts.

Once the 3” C-channel was in for good, I set off building the reinforcement structure that the belly pan would be welded to as well as build in the new and final version of the trans mount. For belly pan material, I decided to go with 3/16” steel. Pretty heavy for what I am doing, but I know I’ll never have to worry either. You can also see be starting on my mini boatside supports that will be added to this later.
