Agree with the differences, I was saying that adding a PT kit would make it the same as an early LC in that the front is not engaged and spinning all the time; therefore, not really understanding why a PT kit is not recommended for a DD.
talk to me about the part-time kit...

Oh, gotcha. Makes sense.
I agree.
There is also very noticeable difference with acceleration and maintaining highway speed up hill. It's not a huge difference, but enough to make it more pleasant to drive.
Before doing the TC part-time conversion, I drove around for six months without the front DS and with front hubs unlocked just to be sure before I pulled the trigger on the TC conversion.
Now, four months after the TC part-time conversion, I wish I did it sooner.
I agree with this. There is a noticeable difference when I drive mine with the hubs locked and unlocked (CDL not engaged in both cases).
If there was a noticeable difference in acceleration, that indicates the front driveline is robbing power in the normal configuration. If so, the 2wd kit should show a noticeable increase in MPG as well.
I have the PTE kit in my rig, and I've driven it daily for most of the winter.
There is no slop in mine.
Like others have said its like driving an older 4x4 with regular hubs. I also like the fact, stuff isn't spinning when it doesn't need to be. I bet if they had hubs from the get go, you wouldn't be replacing clicking birfs
ABS - Mines long gone, and is one of the first mods I personally do on any 80 I own. PTE eliminates it, great in my eyes.
How many people tell there ins agent they lift, lock or put different tires on there rig?
Mileage is nill, if you get 1-2 mpg, I would be surprised.
If i own any more 80's, the PTE will be the second mod I do to it for sure.

I can agree in principle with the statement that it's not recommended. The 80 was engineered from the ground up for full time 4wd. The steering ratio, gearing, etc, is built around the assumption that it will always be in 4WD.
That said, isn't the 80 series sold as p/t 4WD option in some markets (Australia/NZ)? Do they come from the factory that way, or is that a port-installed mod?
I guess I also should have added my ABS is disengaged, too. One of the sensors was faulty when I bought the truck, so I removed them both.

So Beno, am I right in assuming that a typical p/t kit includes manual hubs, AND a spool for the t/c?

I got the same effect just by removing my front shaft. I landed a contract that had me driving about 200 round-trip miles a day for two months, including a 1200' ascent/descent at highway speeds. I took out the shaft at that point to see what the difference would be and because I'm having it made into a double-cardan shaft. There was certainly an increase in acceleration at highway speed, the ascent up that mountain was way easier, and I did gain about 2mpg overall (although the MPG improvment may also be because I did almost no city driving during that period).
If you get thet kit that Christo Slee sells, yes, it will come with the spool for the xfer case as well as the AVM manual hubs.
You will need a CDL switch if you already don't have one.
Sounds like marketing to me. Your truck may be part time and you may be getting 17mpg, but I doubt one is a direct result of the other.
In my experience and multiple accounts of others, a PT conversion does not give a noticeable increase in fuel mileage. Maybe in theory
Not marketing at all. My personal cruisers mileage did increase. Most of our customers don't realize any mpg increase. MPG increase as stated in the previous posts is not the reason for doing this.
We recommend it for the same reasons everyone else does. To lessen wear and tear on components. Seat of the pants acceleration feels quicker and the steering definitely feels lighter.
sdnative, if you really want to go back to full time, i will trade you the center diff and viscous coupler from my spare tcase for your spool setup. that's all i need to finish my pt conversion.
i thought you had longs in your 80 yuppy? if you do, for sure put in the part time kit. if you dont...imo, its money better spent elsewhere. i like abs in a 6000lbg rig as mentioned earlier. its a godsend whenever ice/snow are a factor. im sure it drives alot different...lighter with part time, as it should. but personally, i like the heft of the awd in the steering. feels more positive...more solid.
i was in the same boat with my 3rd gen runner. it had flanges, no selectable hubs. manual hubs was a spendy mod, and really only for piece of mind of less parts moving. after much research, i opted to put a locker up front, than retrofit manual hubs.
some jdm's came with manual hubs and part time kits. those were factory installed as they use the oem aisin hubs, and not aftermarket avm's. small percentage of them came like this. not über rare, but certainly not dime a dozen...at least in the BC import market.
its all about what you want to spend your money on. like beno said, any gains other than less wear & tear on the front end is all placebo.

sorry to revive or 
but i have another question after reading some great info on this page about the 91-92 fj80. seems that year model does not have the viscous coupler as the transfer case is different than the ones the 93-97 models got...so my question is then if i wanted part time 4 wheel drive, all i would need to do is install manual locking hubs and keep the CDL on?
i know that would mean the front drive line would still be turning all the time however it wouldn't be engaging the wheels unless i stop and manually lock the hubs, however would that still cause undue wear and tear on the other parts of the front drive line since even though it would be turning, it wouldn't be under load unless the hubs were locked?
is my thinking on this on track or am i just an
(i assume that is the sign for idiot)
~thanks in advance

Not all Land Rovers are useless!
I am in the full time camp. If you want to know how it feels PT lock your CD and remove the front propshaft, 8 bolts and ten minutes. Around town I doubt you will notice any difference I didn't, start pushing around out of town on bends and you will then notice the truck front runs wide, you cannot overturn the laws of physics.
Saving wear on the front end........possibly but, given the axle is expected to be overhauled say every 10 years, I am not seeing much to be gained going PT. My 94 has the original diff, no nasty noises now approaching 270,000 miles. One of my Birfs is also an original, as I use mine pretty hard on and off road I will be changing knuckes and Birfs, as PM, last axle work 7 years ago.
Fuel saving again possible but how much I cannot say, I drove mine PT for a few days, certainly not long enough to give an honest answer, I do remember how good it was to get full time drive back under me.
Something else, my recent trip through very changeable conditions, being able to simply press the CDL button was enough to get the 80 through most obstacles, having to get out and manually lock your hubs is not for me, especially when it is muddy or pissing down with rain.
If you paid out for the PT kit you need to justify it, even if you found out the disadvantages too late.

Dave
