:idea: why don't you keep the 80 for heavy wheeling?

Buy a 100 for the other 95%? I would like to have another 80 at some point.:)

Because my 80 is going on 22 years old, the body is rotting out from under me, and it's tired. Don't get me wrong. I love my truck. It kicks ass and takes names, but I can't have 2 and it's getting close to trading up.

IFS doesn't interest me in the least. I would only consider a solid front.

At this point it looks like a 100 Series conversion is way over my budget. I love the 80 and will probably stay with that platform. I am considering a diesel swap and a body swap though.

That could be a pretty cool rig in my opinion

On the Extreme Landcruiser site they were advertising a sas kit you can order and they have the option of an 80 series front axle or a custom built axle. The one they did with the 80 front axle looked fine

I can't found info about it, if you have the link, post it please.

I believe Slee said that the 80 series axle is not strong enough for the weight and power of the 100 series, hence the need for the custom axle.

probably it is true, but what about the well built 80's with turbo? can we say that the scenario (lbs/power) it is similar?

I believe you can do a SAS for $10,000 or less if you buy all the parts and do most of the labor...

I agree!

100% agree, and you right again, unfortunately the 80's are getting older.

I guess that some how and some day the SAS to the hundies will be popular and affordable.

I can't seem to find it on their page right now either. Its probably because when Ryan emailed me about it he said they were putting on the finishing touches and were planning on rereleasing it then. Heres the only pic I could find of it its from the rear

Just know your track width on an SAS 100 will be wider than an 80... and to the best of my knowledge an 80 front axle assembly isn't wide enough for the 100 frame rails...
Click to expand...

The 105 series (sfa) front diff gain extra track width over the 80s front diff housing with there hubs, the actual diff housings are the same, use a 80 front diff housing ,springs and radious arms and chassis brackets, then purchase front hubs (5 stud), disks,axles and diff centre from a 105 series or any post 99 70 series, you can use all bits bare the 70 series axels same spline but different length.
 
Cheapest option:

95-97 80 series, add supercharger. That should take you past the power of a 100 and retain SFA.

Otherwise you are looking at a big and expensive project.

Or, just buy and wheel a 100.

80 with a SC will not keep up with a 100


I would take a 80 with a 100 V8 and 5 speed over a SAS 100

If you add a blower to an FZJ motor, don't you loose the possibility of adding belt drive OBA? After years of having a York under my hood, I wouldn't want to go back to electric.

My sc'd 80 was quicker than my 100. Hundy has higher top speed.

Seat of the pants or real testing? Post your findings

We have done real testing side by side on flat roads as different speeds and grades up to 7% at different speeds. 100 wins all with witnesses driving 80's:flipoff2: On big grades the SC would go flat at higher RPM and the 100 RPM's would continue to climb.

Test vehicles
97' 80 series SC, 4.88, 315's 130k w/ new HG
99' 100 series 285's 150K w/ RTT installed

A 06' LC w/ VVT will smoke both a SC 80 and an earlier 100

I have owned all of the above and from a noise stand point the SC seems faster:rolleyes:but there is when it ends
 
I guess you'll need to decide what really matters to you.

Even a normally aspirated FZJ will feel a lot more powerful than a 3FE. I have and drive both and a 3FE feels like a slightly warmed 2F, where as an FZJ feels powerful and sophisticated like a modern car. While it won't run the doors off a 100 it will travel as fast as you would ever want to go in a road boat like a Land Cruiser. Heck, I just drove my 80 from Sacramento to Denver in 2 days. It's plenty fast except above 8000 feet. I did Vail Pass at 40mph-then I knew I was in a Land Cruiser. Not much 8000 foot driving on the East Coast.

With regards to top speed-that's a silly argument. Who would ever drive one of these at "top speed"? They are barely safe at normal highway speed.

If you are really after power and speed, either get a car, or skip the 100 series all together. The 200 series has enormous power and is a worthy choice.

While I have come to like the 100 series, there is no way I would even consider a SAS. It's too much trouble/expense and the improvement too marginal to be worth it. For overland type travel, the 100 works awesomely well as is. Plus, after seeing Spresso's rear axle trials and tribulations first hand, that would pretty much rule out a 100 as a rock crawler for me.
 
I would hardly consider a 100 series on 36in tires a rock crawler. The body is so long, it would take fitting more than 36's to get you on trails that you can't do with the IFS and 35's. I admit the SAS looks a lot better, but not sure it will take you a lot more places. my $.01...
 
Let me clarify some things:

It is not the axle housing width that is different, it is the way the frame is set up with the 105 and the 100 series that doesn't allow a correct fitment.

The 105 axle housing for the front is exactly the same width as an 80 series: 43110-60400 (locking front axle). I confirmed this because I have one sitting in my warehouse getting ready for my 80 rebuild.

The frames of the 80 and the 105 are actually quite similar. It is the frames of the 105 and the 100 series with IFS that are quite different and doesn't allow a very good transposition of the two between each other.

Of course there are other subtle differences as well (5 lug vs 6 lug, etc.) but the issue really is mating the 80 series axle housing (which is a different and superceded number from the original factory production--the axle housing for the 105 and the updated 80 series is substantially beefed up--so much so that I wholeheartedly recommend the axle housing upgrade for 80 series owners) to the 100 series frame which is where the real issue arises (mainly because of fitting the 2UZ into the frame)--remember there never was a UZJ105, only a UZJ100. All 105's had either the 1HZ, the 1FZ, or the 1HD variants.

The 100 series frame is significantly different than the 105 series frame which is basically an 80 series frame at least for front axle housing fitment reasons.

Anyway, enjoy the pics. Notice how beefed up certain components are compared to regular 80 series factory housings. Connections points have been substantially beefed up, thicker bracketry, better and stronger welding, and a thicker housing as well. :)

Toyota learned from the abuse the Australians gave the 80 series components so when the 105 was conceived as the transitionary vehicle (getting the Aussies ready for the IFS coming with the wagons), they substantially upgraded the components. The 7x vehicles all share the new upgraded housings with different lengths depending on vehicle specifications.

The key really is to get a hold of a 105 frame and transfer the 100 series body onto it. A lot of work, but I think cheaper than trying to mate the 105 axle to an IFS setup 100 series frame.

Just to confirm my theory, the front lateral support is the same from all 80 series rigs as well as all 105 series rigs. Which to me means that the front of the 80 as well as the 105 was set up for I-6 engines of either diesel or 1FZ variety--both of which require a significantly different setup for support than the 2UZ engine does.

Enjoy the pics....

Yes they have... I kept thinking someone would pick it up... Someone needs to low ball an offer and try to get a deal on it...
