Also, the power steering pump decided to poop the bed. I test drove it for about 5 miles and when I got home the reservoir was overflowing and bubbling while it was running. Let it sit over night and now the brand new fluid is kinda foggy red with little metal flakes in it.

I finally got a call back from the Alemeda college referee today. According to him I am good to go. He said the engine family located in the door jamb of the donor truck had to be VCK11LCRMDK and under the hood TTY3.42JG1GK. It does not matter if the ECU is for a 2wd, just as long as it is for a manual transmission. As for the ECU check I would be good to go to get a printout from the Toyota parts department showing it is the matching ECU for the donor truck VIN. According to him these ECUs aren't really programmable and the will be checking that during the inspection. suggested to do what I guess is a smog pre-test to check all the emissions monitors since I dont have the capability myself. However, he said my intake would be up to the shop supervisor's discretion if not having the heat shield on the intake is acceptable or not.  Lastly, the exhaust crossover is still allowed. Fingers crossed I'm going to send it and hope for the best.

I almost forgot about making sure all the emissions monitors are working before setting up my inspection. I've driven the truck about 105miles the last few days and all but the catalyst monitor seems to be working. I understand there is a specific drive cycle that should set everything but I dont really have the place to do it exactly as the instructions say. Does anyone have any tips to get it to read ok?

Normally you can get the catalyst to kick by running down the freeeay for a bit. Itll take two trips.

Today I went ahead and took the truck to the referee. It did not pass. I'm not really surprised but I have a better idea of what needs to be done. Of course the cat monitor was not ready but I also did not have the brake light switch wired to the ECU. So even if the cat monitor was set I would have failed anyway because I didn't know the ECU needed a signal from the brake switch. Go thing is that just those 2 items were the only thing that failed me. The refs said that a couple things could be wrong considering I've driven the truck a couple hundred miles already.
1. The cat could be old and losing efficiency since it is the OEM cat with 160k miles on it.
2. The truck is running borderline too cold on the highway. It usually runs about 185-188* when it below 90* outside. It has the OEM 180* thermostat so I may try putting in a 192* thermostat and see what happens.
3. The ECU might be losing power when the key is off so it resets some of the monitors every time I shut it off.

They also told me I got lucky. There are 2 versions of the 5vz. One with the EGR and one without. The documents they had weren't clear on how to tell which one is which so they looked up the past smog test history from the VIN on the donor truck.

Other note, the truck tends to very slowly over heat while it's not moving and given any throttle even with the cooling fan on. It boiled over once when they forgot to turn the fan on despite me telling them about it and the instructions I taped to the steering wheel. I'm not sure if I need to do something like get a 2nd fan or a bigger fan. Also I dont know what the were checking but it was getting up to about 230* when they were revving it to 2500rpm. They even had a 2nd larger fan blowing at it from the grill.

My referee knows all about the different ecus. I had to go out and buy a different one and find all the egr components to make it legal. He said he goes by weight class and the t100 I have is a heavy duty t100. So that's the reason why I needed a different ECU and egr. Bunch of BS.... Still haven't started on the swap. I want to install all the new parts on the t100 first to make sure I don't have issues later when it's in my truck. Good luck with your swap.

Quick update.

After 3 weeks fighting with one supplier and ordering from another, I got a new catalytic converter. Got it bolted/cut/welded in today. First drive out and the cat monitor is now set. I'm 90% I got the brake switch input wired to the ECU. I want to have someone with a scan tool verify it is working correctly before I schedule my next inspection. Also got the 190* thermostat in and a new 16" 2500cfm Flex a Lite fan hooked up and it is maintaining the coolant temps much better.

Anyone happen to know another way to check the brake switch input is working correctly? I might be paranoid but I wired it using a wiring diagram from a Haynes manual and I just dont quite trust it.

Just check to see if signal changes with brake input. Simple as that.

10 months later we have success! They inspected and passed it all in the same appointment.

Now that the engine is done, I'll be moving onto the rear axle. I need an IFS width axle, nee perches to correct the crappy pinion angle and a traction bar because these springs wrap REALLY bad with the new power. I also want to try and go from the angled shock setup to straight up and down if I have enough room.

Nice work!
Do you have any concerns about the toyota axles holding up to the 3.4 power?

I have been casually looking for a 3rz for years with no real luck.  The 3.4's are available but have never really considered the option, for fear of breaking parts.

Just like anything else, it depends on your driving style.

Im not really heavy right foot but..... I broke two 21 spline inputs in my rear case. (4Ds and 4.30s)
Ive since gone 23 spline and 37s.

Reality is, people destroy axles, trans and cases with 22Rs

I'm not concerned. I'm really easy on the truck and not pretending to be an ultra 4 rig. Eventually I'll have chromolly axles front and rear.

 I may have to give the 3.4 some consideration. Im not to hard on my truck either but do like the idea of being over built and knowing it can take more than I give it.  A first gen with a 3.4 has got to a blast to drive.  :driving:

It is Haha! Driving up highway 88 I'd have to use 3rd or 4th just to get up the mountain, not to mention the loss of power above 5-6000ft with the Weber. Now I could leave it in 5th all the way up if it weren't for all the sharp corners.

Small updates.

Swapped in a 1987 rear axle and changed the shocks from angled to straight. Before I would get a lot of side to side rocking when going over obstacles, but now it is way more stable.

I have about 7000 miles on the swap and I have had zero issues. I ended up relocating the battery from the bed to back under the hood. I also got a decent deal on some used 37s. 35s feel too small with 5.29s. The 37s feel way better and the spedometer is even accurate.

thanks for the write up and welcome back to Commifornia
Have you done any serious offloading since the swap? Just wondering if the weight of the 5vz makes a difference.  is it super easy to pass people on the highway now?

Yes it is very easy to pass now in 5th gear, no more down shift and pin it.

I did drove it to Prarie City. I think my 6 leaf RUF springs were over sprung for the weight of the 22r. I even hit the short course and it drove great. The rear F150 spring are also over sprung for an empty truck.

I finally got to hit Slick Rock and Deer Valley to test out the swap. Found I forgot to turn the fan on a couple times and got close to over heating. After turning the fan on it cooled down pretty quickly and ran all day with no cooling issues. The power is perfect. Tons of power down low like the 22r but doesn't run like crap at high altitudes and I can do 65mph uphill. I definitely need a 4.7 gear for the rear case with the 37s. Does quite crawl like it did with 35s.

https://youtu.be/h1LBFuEQZCk

Turns out I am a bad engineer. My rear shocks ended up touching my unbolt plates at full stuff without bump stops... So I made a new upper shock mount and tilted them inward, added bumps, now no more problems. Also found the engine would shift forward and back under acceleration. Ended up swapping the motor mount for some Trail Gear bomb proof mounts and it seems to be working better now.
