Hello everyone and welcome to my first EV conversion project. I love cars. Driving and modifying them and everything that goes with them. I like racing and autocross, taking relaxing drives on twisty mountain roads, and driving on gnarly 4x4 trails.

My conversion is a 1996 Toyota Land Cruiser FZJ80.





For my first project I have chosen a large, heavy, inefficient, 4WD SUV. Makes sense right?! To me it does and this is my rationale:
-There is a lot of space to mount things.
-There is not just space for lots of batteries, but the GVWR of the vehicle allows for 1400lbs of cargo in the original configuration.
-The original 6-cylinder engine is unreliable (for a Toyota) and underpowered, why keep it?
-The chassis and axles of the Toyota Land Cruiser are legendary due to its incredible off-road prowess and durability.
-EVs work just as well at sea level as they do at 13,000ft on a mountain.
-Land Cruiser values, especially 80 series, have been going up and up and up so now is my last chance to own one and an EV conversion justifies it to my wife!

-Most importantly, as a dedicated off-road rig this vehicle will be driven almost exclusively at very slow speed less than 20mph and very short distances. The normal 4x4 trails I do are 5-10 miles long, a really long trail is 20 miles. The appeal of silent running, no fumes to smell, and smooth torque delivery appeal to me in a 4x4 vehicle. With Rivian, Hummer EV, F-150 EV, Alpha EV Truck, etc I think the writing is on the wall about 4x4 EVs and how effective they can be. Better jump on the bandwagon!

Your skill level with auto mechanics and fabrication
I have had 4 or 5 dedicated "project cars" in the past with various stages of upgrades, modifications, and custom work. I have rebuilt engines from a bare block, assembled cylinder heads, rebuilt suspension, brakes, exhaust work, etc. Rebuilt engines stock and also rebuilt them with aftermarket parts for big HP. I swapped the engine and transmission in my daily driver and drive it all of the time. All of my vehicles run on E85 fuel (cuts your carbon emissions by about 40% believe it or not and it's cheaper and makes more power). I can weld, cut, grind, paint, and turn a wrench. I currently own 9 or 10 cars (I think I am forgetting one).

I have a lifetime of experience with RC vehicles and I build and fly UAVs. Soldering, wiring, designing circuits, and crunching amperage and voltage specs is what I do nearly every day. I'm pretty much 100% self-taught or learned from mentors, I have no degrees or certifications except from the FAA so please be kind if I am doing something wrong :whistle:

The range you are hoping to get (how many miles/charge)
20-30 miles range with my initial build would be a good starting goal or about 2 mi/kwh.

What level of performance you are hoping to get
Enough to drive around town and drive on local 4x4 roads and trails and eventually go to Moab for the real terrain. I will tow it if needed.

How much money you are willing to put into your project
Whatever it takes but likely will cost $10k or so before it drives under it's own power.

What parts you've already considered, if any.
I have already acquired a 2013 Nissan LEAF SV which I will use as a donor for my motor, inverter, DC-DC, chargers, and battery pack.


Short term I just want to get it running. Long term I have lots of ideas. Assuming I have a fully functioning fully electric 4x4 truck there is a lot of stuff that I could do with it. I am now researching DIY wind turbines and river water turbines and of course have been messing with solar for years. All of which I eventually want to harness and do a fully-electric "Overland" trip through the wilderness of Colorado and Utah and maybe beyond. Of course that is probably years in the making, but it is my long term goal.

My own personal EV history: I have owned a 2013 Nissan LEAF SV similar to the salvaged car I bought. I owned it for a year and then sold it as the battery degradation started to really take hold. I really enjoyed the EV lifestyle on those perfect weather days when I could drive everywhere I wanted. In the middle of winter when the heater would barely keep the windshield clear on those dark nights trying to coast down hills in order to make it home....didn't enjoy that so much. During my EV ownership I got to understand what it is like to live with an EV, charge at public places, get ICEd at the charger, plug in at home every day, and check a location's elevation before driving there.

While owning the LEAF I read about a guy in Arizona who set the record for the longest distance driven in a 24kwh LEAF and it was over 180 miles! Yes that's right, a 24kwh LEAF drove 186 miles on a single charge. The kicker? He did so at a maximum of 24mph and drove for nearly 8 hours!

When I was a kid I loved RC trucks. I loved the fast ones that could hit the big jumps. Unfortunately, the little NiMh batteries wouldn't run very long at all, 10 minutes or less. Then I got into RC rock crawlers. Little trucks that were geared really low and built to drive very slowly up rocks and other challenging obstacles. Well, guess what? That same crappy NiMh battery that only lasted 10 minutes in my fast truck, actually lasted well over an hour in my rock crawler! Guess what I learned that day.

The biggest enemy we have as EVers is speed i.e. wind resistance. There is no wind resistance to speak of at less than 20mph. So if my EVJ80 Land Cruiser can go 20-30 miles around town, maybe it can do 30-40 miles offroading?

If you have time to make a stop in Grand Junction when you head to the wrecker games I'd love to see the cruiser! You could also see the project I just finished of putting an fj80 front axle under the front of my 2004 4runner.

Not sure if we will have time to stop by but maybe on the way back. SAS 4runner sounds awesome 👍

Been working on my EV80 a little bit getting ready for next week. I replaced the rear driveshaft; I had to shorten the rear driveshaft because my t-case got moved back slightly with the new drivetrain. I shortened it with a grinder and bandsaw but it was only temporary.

I had another OEM driveshaft shortened properly and balanced and serviced and now that's installed. I still have the stock front driveshaft, it's just running with a little more separation in the slip yoke. It's still within spec I think but if I need to properly fix it I'll do so.

Otherwise the truck is running great. I'm so excited for next week in Sand Hollow. The terrain looks insane. There aren't very many EV chargers in the area however.

Where do you get the spec for slip yoke engagement?

If the fj80 is like my 4runner, there is a seal on the slip yoke to seal the splines. I just went through getting my driveshaft lengthened and on full suspension droop you want the sealing surfaces to maintain contact. Here are pictures of the drive shaft engaged properly and the male part of the splines.

It's more important with more suspension travel

Yep mine still is covered. If I get a taller lift I'll probably need to address it but I've checked it while flexing on my trailer and it looks good. Will have to try and remember to take a look on the rocks in Utah.

P.S. - awesome 4runner! Is it a V8?
V6, until it's electric some day!

Made it to the top of San Hollow dunes! This truck is amazing. It really climbs anything.

Reddit is being a bit brutal to this builder and build at the moment:

https://www.reddit.com/r/electricvehicles/comments/11bm4rq
A lot of exposure can sometimes backfire.

And, no, I'm not posting on that one, just reading.
Of the 19 replies only 2 were negative, and they were still constructive. 17/19 is 89% approval rating for some rando reddit users. How did it backfire? The TFL Video has 21k views and by far the vast majority of comments are positive.

When I went to Sand Hollow there were 4000-5000 people who showed up to the event and several people mentioned they saw me on TFL and loved my truck. I think it was a massive success!

So yes, you are right that a lot of exposure can sometimes backfire. For instance people become envious and take cheap jabs at you from the shadows.
A top speed of 64mph implies it takes 80kW to run at that speed or an efficiency of around 1 mile/kWh, or it's speed limited by the truck's gearing/tires.

If the latter, 160kWh is not going to make a lick of difference except acceleration or grade climbing at highway speeds, which may cook the motor/battery due to inadequate cooling.

I'd leave it alone and build something else.
The speed of 64 mph is not the top speed, that is just the top speed record currently. I have not taken it faster than that. As I stated earlier when showing my gear calculations that the top speed should be 70-75 MPH which is limited by the maximum RPM of the motor.

Yes doubling the output power from 80kw to 160kw is "going to make a lick of difference." A big sloppy lick. The main thing you do when driving is accelerate...

Who cares what you would build? Go make your own thread.

I enjoyed the video and look forward to seeing the cruiser at cruise moab. Have you done any updates to the Landcruiser lately?

Yes, quite a bit actually. You can check out my Instagram I am pretty dissolutioned about posting on this forum any longer.

@seatosummit it looks like you have a really nice 914. Those are up there with one of my all-time favorite cars.

Let me know if you want to test out my LC I'm going to be doing a bunch of events with it this year.
Just seeing this! Would love to test it out when you are on the west coast!

Not sure why but this video exploded on Instagram with over 10k views where my others don't get anything like that. Not sure why I like my others more but there must be something to it:

Tim of Gamiviti and I hung around today up in the misty mountains and took the EV80 out for a little cruise. Check it out!


Gamiviti is the maker of my roof rack and specializes in solar powered gear like fridges and water storage systems for overlanders.

On Saturday I went wheeling with a couple of other 80 series friends. It was a close trail but still out of reach unless I used public charging. I used about 1/4 tank of gas the whole day in my tow rig and when I charged up my 80 it took about 15 KWH, or about $1.80 worth of electricity. I would have used most of the tank of gas if I had wheeled my gas truck the whole time... It is actually worth it to tow to the trailhead it does save gas!
