OK, so not really a comparison thread but more of a better/best thread between the 1992 HDJ81 (now sold) and 1996 FZJ 80 (current vehicle).

So for a little background:

Two years ago I bought from an auction in Japan a 1992 HDJ81 with 92,000kms. Shipped it to Nanaimo, British Columbia then drove it home. I took out a hokey lift kit that was about 4". The rear lift was just some 4" spacers with the original springs. One shock was toast. It was a little sketchy driving it home. I put in an OME 2.5" lift right away and was satisfied. Put BFG 33" tires on it. I had a friend help out the anemic stereo with a little of this and a little of that. The front bumper was taken off and a stock JDM winch bumper and winch was put in place. The diesel was amazing. I learned so much working on this truck as never really did much other than change the oil in previous vehicles. IH8MUD was a great resource for this vehicle (and still is for the current 80).

18 months after stating that she loved driving the RHD apparently the novelty wore off because my :princess: said she was done with it. I hope the novelty of me doesn't wear off soon. Ten years so far and I am still around, despite my downfalls.

So the search was on for a newer LHD 80. There aren't many 80s for sale in my part of the world, that is are any good or are too high priced. Sadly the 80 disappeared from out part of the world earlier than in the US.

In October I flew to Sacramento, bought the new-to-me FZJ and drove it home. Immediately put some Discoverer STTs on it in a little bigger form (not as big as many of you) and for the past 2500 miles have been very happy with them.

Now for a few noticeable differences between the 2 trucks:
1. the engine - one diesel, the other gas. The gas engine is totally anemic in comparison with poor mileage but oh well, we still wanted an 80. Miss the sound of the diesel (mainly the turbo winding up).

2. the brakes - the 96 brakes feel so much stronger than the 92s.

3. the dash - I know it is a little stupid, but I like the 96 dash way better then the 92. Just not as dated I think.

4. running boards - the 92s looked way better, but either way doesn't really matter because at some time there will be some sliders added to the current truck. I would take them off but with little kids they are needed right now. Hopefully some offroad travel won't rip them off in the meantime.

5. seats - loved the fabric seats of the 92 much better then the leather. I think a leather changeover will be happening in the future.

6. icebox - travel with the kids was sure nice when you could keep things cold/icy in the 92. No, I was not drinking and driving therefore making it appear the kids were quieter than they really were!

7. 3rd row - love it in the 96. Wished it existed in the 92 from the day I saw it in person. Can pack friends around when they come to visit. Can also pack a bunch of kids (mine and a buddies) when exploring.

8. color - definately like the Moonglow Pearl better than the Gunmetal Grey (not sure it that was really what is was called). Colour isn't everything, but I didn't want a dark color with the 96.

Below are a couple of pics of my HDJ81 and the FZJ80. I washed both today and snapped a couple because I would love to see another HDJ81 in my driveway in the future. (A neighbor 2 doors down bought my HDJ so I still have the joy of hearing it start up each morning. )

Thanks to all you people out there giving out information about these amazing Toyota machines. Keep it coming!

nice comparo brad. pretty much sums up what i expected between the 2 every time i think about choosing one over the other. i love the suede interior of the 81s far better than the leather of the 80s...however i think the leather is much more durable when it comes to kids, milk & juice stains, lollipops being stuck to the seat and regular wear & tear from camping trips. the lack of the 3rd row in the diesels (they were available in gasser 81s...not sure why the diesels were omited from this option) was one of the 2 deal breakers for sure. what else ya got on tap for the 96?

must be nice to be able to see your old ride whenever you want...does the new owner ever take it out into the bush?
 
Makes me miss my 81!!
 
Interesting comparison info Brad.....thanks.

I brought mine up from Seattle about 2 years ago, so I know the drill. Never could wrap my head around the idea of a RHD truck, just too weird for me, couldn't do it, even though there are tonns of them in the lower mainland now. Lots on the island too I suspect.

So you're saying that the 96 gasser feels gutless compared to the diesel. I would have thought it would be the other way around. That diesel must pull hard. Interesting.

Having driven a turbo-diesel 81 as well as my FZJ80 (both with automatic transmissions), the diesel does feel like a better match for the truck. I don't find my gas engine particularly slow, but the diesel just felt "right". Neither engine is racecar fast though.

Someday I'll buy an 81 and swap the engine and a 5 speed into my truck like Sheldon did (very jealous of that install!). Until then, I'm content with the 1FZ-FE.
 
2. the brakes - the 96 brakes feel so much stronger than the 92s.

Very interesting comparison.....what was the build month on your HDJ? Just wondering if you had the bigger brakes with the 16'' wheels, built after aug '92?
Gotta love that diesel torque curve!

Cheers,
Gord
 
hey cool guys want a 81 for the fridge ha. Hmm gas 3rd row diesel no 3rd row what is it with this guy toyoda he comes up with something cool and procedes to take away. The biggest being the straight axle when adding v8s.
 
Well...you can always rip out the gaspot and drop in a 1HD-T in the near future. Especially since the condition of your FZJ80 seems to be good, it will be an excellent body donor...lol. Then you'll have the best of both worlds. :cheers:

My 96 will be getting a lift, bumpers and down the road a 1HDT! :bounce:

Neither is fast but the pull of the diesel felt so much more. You did have to wait a few seconds for the turbo to wind up though.

I am totally with you on this one.

I don't remember the build date, but my 92 had 15" rotors. In hindsight I think that calipers were probably in need of a rebuild. I have the bits and will do it for my neighbor.

As stated above, this is the plan! I can't wait. Just need to save up some $$ for it. Stone, I love your swap. I have bee following it!

I wonder what would be easier, a LHD body/steering assembly swapped on to a diesel engine drivetrain/chassis, or a diesel engine/trans swap into a LHD chassis/body? I'm thinking the engine swap route is easier and has already been done. Either way, I want to create an HDJ80!
 
thought your 81 have rear drums .. in this case aren't a fair comparision about brakes .. and I'm agree with the dash .. :D

My 1990 Hdj81 has 4 wheel discs, the 15" ones I guess, but 4 of them anyways.
 
My 91 HDJ80L is about same age as your 81, I think most of US gasser 80 target is for mass market, and not much of lexury where added, but diesel series 80 was made for lexury and economy, mainly to export to 3rd world country, where their buyer is ready to pay what toyo ask for: think about 3rd row seat, icebox, dual air, and strong 1HD-T, I found total of 3 expansion valve in my truck~

I think swaping instrument panel etc aren't that hard, I have see cars in centro america that you won't notice the change if owner don't tell you, used car dealer import from JDM and swap the side before sale.

The firewall swap will be pretty involved also with all the steering components to think of. Might as well do the engine swap.

Brad...look forward to reading about your build. :cheers:

Is the diesel actually faster than the gasser? I assumed the gasser has more h.p. and I think even more torque, but not sure.

What is the fuel mileage of the diesel, out of curiosity?

Don't really think the diesel was any faster but just felt like it had more grunt. The HP was 168 and about 270ft-lbs torque IIRC. Being that the gasser makes about the same torque who knows the difference I was feeling (maybe I just liked the diesel better)?

I was getting into the low 20s on the hwy with the injection pump not on factory setting. I know guys that get 25MPG on a stock HDJ81.

The build will be happening slowly but over time will be posting stuff here on MUD.

Yeah, I agree. The recent thread about a body swap had me thinking though :D

I'm definitely looking forward to your build thread when it happens!

I've never driven a 1FZ, so I don't know how to compare that engine...

I can tell you that there is a night and day difference between the gutless and thirsty 3FE that came in my FJ80 and the 12H-T that replaced it. Even before I bumped up the boost on the 12H-T, there was a big difference.

The two engines being from the same generation, I think it's a fair comparison to make.
 
I have a FZJ80 mostly stock and running 285 and HDJ80 few mods and plenty of diesel running 315 both stoc gears ... both manuals ( one H151 and other H150 )

the gasser it's fast .. and she take speed easy, more easy compared to my diesel .. the gasser perform better in HW it's more smooth and can handle ( or at least I didn't like to use my 1HD-T more than 3K rpm for long periods ) more rpm .. easyr for more time.

The HDJ80 es beauty for hill passes ..and off road .. the 1HD-T have more torque and you can feel it ..
