Kyle, he has the old fab side of the old shop.

Jesse, that's pretty cool. At least it will get used now. It moved pretty good out at the hammers in 13. Did you change the wheels and he kept the other ones for the other truck?

I know, but you saw all the machines and tools he had packed at the other bldg right? Add the TT that didn't go with you I figured he'd be out of space for sure.

Cool deal! My local club buddies have built 2 80 series buggies on the cheap and they work awesome.

Yeah, super stoked to have an opportunity to finish building this thing, and to own it! Nothing else I'd rather build or drive right now. Worked out a trade with my brother for those OMF beadlocked Alcoa wheels that he pulled off our Tacoma a while ago. That little thing didn't handle very well with 35's on 17's, so he re-geared it and went back to 33x10.5's on 15's. But those wheels are perfect for the truggy. Each wheel is over 16lbs lighter than those Centerlines, and they're an inch narrower, with the same backspacing.

Simple version. He's got as much in the tires as in the truck.

I dont remember ratio, kevin doesnt either. Thinks its as low as we could go since it wasnt getting any tcase mods. Stock rear shafts, longs in front.

Ah, thanks anyway. No big deal. Easy enough to figure out. What do you think about driving this thing on the street with those Longfield shafts up front. Read something about how they might wear-out prematurely?

The stock (slightly modified) suspension is capable of cycling about 15" of pretty clean vertical wheel-travel, so we would have had to limit travel if we used shorter shocks. 15's probably would have been just about right for the stock fronted, which cycles about 13" of vertical wheel-travel, but we had room to fit 17's, and it's convenient to run the same shocks at all four corners.

So these are FZJ80's huh? Just noticed that while I was doing some research last night.

There are around 40k on my rcv 80 series shafts. If you are that worried about them you could do a part time conversion. Seems you like to tinker, but personally I wanted to maintain the awd.

Fzj's are '93-97 with the 1fz engine. '91 and '92's are just fj80's

Yeah, this was a '96 model. Thanks for the feedback on those shafts. Some of the stuff I was reading made it seem like it would be similar to running 300M u-joints on-road. Would definitely prefer to keep it AWD. Removed the selectable hubs from my Tacoma, and that's got an Atlas in it, but run it in 4WD almost all the time. Handles so much better. Do like to tinker though, and was looking into diesel swaps. Was thinking about a 3.3L Cummins with a 5spd, and then found out about the medium-duty Mitsubishi engines and similarities in the transmissions those trucks use. Looks like that would be make for a pretty straightforward swap. Curious to weigh this thing. Know it's lost some weight, but the fuel economy is gonna be abysmal and I'd like to DRIVE this thing. A lot. Runs great for now though. Not going to mess with the drivetrain any time soon.

Finally satisfied my curiosity and weighed it today at a local rockery. Empty tank and no spare tire, so lost around 500-600lbs? Not too bad considering all the tubing in this thing and the weight of those wheels/tires.

2570: front
1620: rear
4200: total (off by 10lbs)

What was the weight? Did you omit that part on purpose?

No, that's weird. I put the weights. Must have accidentally clipped them while posting.

I think the factory curb weight on these is a lie. I've yet to see one scale less than 6k lbs. I'd say you're doing awesome at 4200lbs

I didn't see Booger's on the scale my stock 80 with the exception of a bull bar (no winch) weighed in at 6500lbs with me in it and I weigh less than 200lbs.

Whoa, 6500lbs!?! Forget how much tubing I put into this thing, but would be pretty easy to figure out. Just have to fire-up SolidWorks. Haven't ever driven a stock FZJ80, so I don't have anything to compare it to, and don't even know what gears are in this thing, but it's a blast to drive. Wondering about fuel economy. Might not be too bad around town. Gonna get another set of wheels/tires to run on the street, and minimal bodywork but it's not exactly sleek.

Anybody have CAD models of the oval insert and/or hood for an FJ40? Also willing to buy those parts to cut-up and modify if the price is right. Located in the bay area, but would be willing to drive a reasonable distance to pick up these parts.

Haven't had much time to work on the truggy, but I've started modeling the bodywork. This is a good excuse to practice surfacing in Solidworks, but doubt I'll do anything more than re-skin it with sheetmetal anytime soon. Too many other things I need to finish first.

Started the re-registration process at the DMV. Title was surrendered when this thing was totaled, so had to apply for a new salvage title, and of course it's been a pain in the ass. Was able to get the VIN verified, but it's not quite ready for the brake and lamp inspection or smog test. Was planning on wheeling it through the summer with a green sticker, but the DMV shot me down. Told me that I can't get a green sticker until I either finish everything required to re-register it, or junk it. Ugh, fawk that! Don't want to have to start all over again. So think I'm going to try to make some time to finish this thing sooner than later.

The DMV did give me a 60-day temporary operating permit though, and it's expired now, but you can bet I made good use of it! Drove it over to Santa Cruz one afternoon and it handled great over 152. The suspension isn't set-up at all, but it still handles a lot better than a stock Land Cruiser. Also checked the mpg on that trip and burned exactly 5 gallons of fuel in 75 miles, and we were rallying pretty hard. Will be pretty stoked if this thing averages anywhere near 15mpg.

Anybody want to build something like this? Now that I own it, can share the CAD files...

krazytoy is selling a stripped FJ80 project for $2000 that would make a great starting point for a project like this. Could turn that into something pretty cool for less than what, $5000-6000?
