FZJ80 becomes LSJ80 (1 Viewer)

[NCtoyota]

Doing the head gaskets? This engine was pre factory MLS gaskets and will leak coolant if it isn’t already.

Thanks for all the feedback and advice. I read through a lot of your posting on here to help get the ball rolling on this project.

I am a tragically slow driver as it is. I barely break 60 in my 4runner and cruise it like it's a ranfla.

I plan on using the mechanical fan. To start I will be using the stock radiator but my back up plan is a Ron Davis radiator.

I am not rebuilding the engine at all at this time because it ran fine when I pulled it. The grand plan is to make it all run and drive then make improvements as necessary. I will also be getting another engine to rebuild after I am done with the swap.

The reason I am going with the Holley is so that I will completely own the drivetrain electrical architecture. This is the third engine swap in a Toyota I have done, and they were all integrated harnesses. Troubleshooting becomes a challenge on the trail because I have to remember what I have done and it is impossible to rely on the FSM because it's not factory.

It also helps that I have a friend that tunes Holley systems.

75!! You're a wild man driving these toasters on wheels that fast. I'll roll 65 top end. I've accepted that it was never made to go fast. Out west it was exciting getting my doors blown off my 60k pound semi trucks. Thanks for input.

The Internet is full of 4l60e haters but has yours been reliable? I plan on installing a Corvette servo.

I even get up to 85 sometimes, but that’s about it.
All I did to the junkyard motor and trans was a new water pump, knock sensors and all new gaskets.
The trans has questionable fluid when I got it. Changed it, and filer. Two solid years of use, but the heat of slow moving crawling killed it. Rebuilt it with better stuff and added a 10 Amazon fan to the stock cooler. Seems a lot happier now. With the shift kit it’ll even grab a second gear scratch from time to time.

Hell ya. More parts in the mail. I received the motor mounts and A/C adapters from cruiser matt's.

I cruise the interstate at an easy 80mph. 4.88s though.

Pshycopath!

That's 128km/h, would happily do that all day in my 5speed fzj80. Hills do knock a bit off the top. Though i think, not as much as the autos

Day 4: Adapter install.

I ordered the Marks 4wd kit through Advance Adapters because it was about $100 cheaper and I saved on shipping ($1472 adapter+$35 shipping+$100 NC taxes). They had one in stock and it took about a week to make it to the east coast. It didn't come with stickers so I won't be able to plaster my back window for street cred though.

Day 4 continued: Dust controlling my driveway.

ya ya ya. stupid automatics. At least I had already drank my coffee.

I cut the shaft following Marks 4wd guidelines of 211mm (8.307"). I marked 8 5/16" and cut on the inside of my mark with the thought of the cut off wheel being a 16th and my square being a 16th.
Hopefully I'm not installing a new output shaft. The instructions were somewhat unclear because it said how to measure, then mentioned installing the 4-6 bolt adapter to measure.

I read multiple times in the 8x swapped forum that the provided hex key "sucks". Now I see why. I decided to go with some hex head bolts instead of cutting my Allen key. Notice the "smear" of RTV as Marks calls for. I have never heard that term before, but I'm stealing it.

Chopped and smeared. Thought about making paper gaskets. But that's a future problem.

Sexier than Hulk Hogan ripping his shirt at the RNC.

Yes, I used simple green to clean the transmission case, yes, I know it makes it corrode a bit.

SO! I saw a couple posts saying that the T-case adapter threads like to strip out. I decided pre order and to insert Heli-coils (M12x1.25). BUT I don't think I really needed to. Looking back I should have also Heli-coiled the 4-6 bolt adapter to keep it all the same.

Purple X's are so I don't forget the dowels.

Personally I would rather have the 6l80e for the low first gear. I spent significant time driving with my dyno tuner guy to get the shifting just right for my 4l60e. Pump pressure for the clutches was bumped up. Then I had a more aggressive tune flashed for tow haul.

How was the swap from 4l60 to 6l80?

I never upgraded. I'm still using my 4l60e. Just saying I would prefer the 6l80e. But the 4l60e gets me to where I want to go.

Word.

If we're dreaming a ZF 8HP70 is better than anything GM makes.

I Finally have gathered all the parts I think I'll need to get this show on the road. One of my internal goals was to beat my scheduled oil change on the 1FZ. I have about 1k miles left.

In the meantime I chased an electrical problem that ended up being a connecter that wasn't seated properly after I changed my evaporator last summer.

Not the locker side, but will need to be addressed.

Factory XMSN cooler started leaking so I replaced it. My mighty vac brake bleeder kit made it super easy to find.

Front locker also stopped working. Cleaned it up and works again.


I also installed a 105 sector shaft.

I had a ton of gremlins when I first got mine running, absolutely hated I did the swap for a while. But now that I have it all sorted out and reliable best thing since slide bread! You will love it! I have stock gearing and 33's(tallest tire that will still fit in garage) and cruise to work 75-85 mph no problems getting 13-14 mpg doing it.

What type of gremlins if you don’t mind me asking?

A lot of my problems were caused by not using a stock motor. I have found there are a lot of people that can tune a stock combo but when you build a higher powered motor the field gets smaller. The company that did the installation hired a pretty big name company to remotely tune it.

The installer used too small a tube for the MAF, 3.5 instead of 4 inches.
Fans were wired wrongly causing it to run hot
A lot of things were loose causing wiring issues
Turns out he is a installer more than a he is a mechanic

The engine builder used wrong rocker arms

The tuner totally missed the tune probably because of those issues

When I picked it up I didn’t even make it home before it went in limp mode. After I returned it 3 times installer told me he couldn’t help me I needed to take it to the tuner and pay him to fix it.
I figured out the maf part out myself and fixed that. Then carried it to a local shop (Lane Culver) who I now know is literally a genius when it comes to LS engine swaps. He called me after lunch next day told me what was wrong(rocker arms and tune mainly) I told him fix it and he did. I love my 80 now, it is unreal how much power it has!

Where in NC?

That dirt and tree preview looks like eastern half downhill of RDU.

First time seeing this thread and my guess was Southern Pines.

Just about wrapped up with this OM617 swap in a pickup that'll free up some time to get after it.

You weren’t lying’!

ya ya ya. Not the best locating for a glow plug relay. I'm scared to drop a wrench on that 2AWG wire.

The oil pickup has been keeping me up at night for months. I felt like it never really seated well in the block. Then the other morning I was panning through the summit catalog and found an oil pickup tube brace that uses both bolt holes on the block. Reviews on it mentioned it didn't fit well universally on welded pickup tubes so instead of hemorrhaging more money into this project I made my own. Since I just read that a lithium battery plant was on fire and my tin foil hat was already on, I added a little safety wire.

 

[NCtoyota]

Finally getting after it. Should be able to pull the motor tomorrow morning and then get to cleaning and cutting.
