109 power

Trying to come up with ideas to make a 109 more versatile as an overlanding/commuting. It's currently fitted with a 200Tdi mated to the Series III 4 speed.
The owner has indicated that the wish list includes a/c and maybe an automatic, and really likes the Series t-case levers and function, ie: 2 wheel drive as the default.

What powertrains have you seen and what worked?

What didn't work?

Looking forward to see what comes out of this!

I saw somewhere that Matthew Jackson out west is doing a GM 4.3 V6 transplant. I think that's running into an NV3500 and a series tcase. You could probably stuff an automatic in there instead. Mark Garrenton had done one a while back I think using a Dana 300 tcase

The only way to go is with either an LT77 or R380 stumpy mated to a 1.4 LT230 gearbox. I'd go R380 personally.
I have the uber-rare aircon bracket and a new Sanden pump/clutch along with the tensioner pulley for the front cover. Since I pulled that engine out they are now available.
You will be putting in a R380 seat box and tunnel and altering the Series bulkhead panel to mate up the new tunnel cover. Floor on the RH side will need to be recut.
The autobox is just too long for any series. Well, actually you can make it fit but it really takes a lot of reworking the chassis and drive shafts.
The main issue with AC is siting the evaporator. I have been noodling on that for months and still have no clear answer. I am trying to keep it looking 2A on the inside so that has been a major part of the challenge. If that isn't a concern then you could probably get by with the defender ac/heater box. It's a super tight fit under the wing but it'll go. The plenum can be bought from vintage air or the like. I am using a late 2A steel box plenum that I am stretching about 14 inches.

I think Himalaya did an auto in a nice green 109. I don't recall if they kept the 2wd and shifters and I doubt it was a tdi. I'd be too concerned about the sluggishness of an auto behind a 200. Maybe others have a brighter view though than me.

The 109 referred to above, I had a fresh 4.0 and automatic transmission installed. Although it was quite nimble for a 109 it still felt that it needed more power.

The weak points.
Even with Dynamatt the floor boards became unbearably hot. The seat box as well. In retrospect the exhaust needed to be ran differently to take it away from the seat and leg area. But the headers/exhaust manifolds being so close to the bulkhead and floor area just transferred heat directly into the cab.We wrapped the headers and pipes, which helped considerably.
The motor being crammed in such a tight space makes for cooling issues as well. Dual electric fans pull the air thru the radiator, but its still a big lump in a small piece of real estate.

I know someone who put a Chevy in theirs, they like the engine and power, but constantly have heating problems because the install really needs to include a very different radiator set-up.

Before I got the 110, I was toying with some kind or change in the Series. I settled on a 200tdi with a five speed as my ultimate set-up. However, if I understand correctly, the non-turbo 2.5 will fit the original transmission. Then get an overdrive and you should be good. Global Roamer Corporation That would have been my real-world option.

Why hasn't anyone suggested Teri Ann's website as a starting point?

iirc, ashcroft sold a lt230 rebuild that made it 2wd, extra stick could be a dummy stick.
I'd go stumpy r380 with above keeping the tdi

I would keep the 200TDI and put a 5 speed in it, either the LT77 or the R380. Buy the kit from Ashcroft that will adapt the Series Transfer Case to the 5 speed and he keeps his original shifter configuration (High/Low/4WD/2WD).

All that work and you left the original time bomb expansion tank?

Looks nice otherwise.

Ashcroft has a part time lt230 conversion that might answer your need for more levers!

What is wrong with the truck as is? Unless it is blowing up series III transmissions I would leave well enough alone. That being said, stumpy R380 or 4 cylinder Lt77 to series T-case is a doable conversion. Was the truck a six cylinder originally? That makes it much easier. I can't see an auto working with a series breakfast as it is just too long. If you want an auto, you would be better off starting with a defender.

Also, I have that part time conversion kit on the shelf somewhere.

I run a standard Series transmission with over drive behind a 3.5/3.9 hybrid courtesy of our very own Junkydog. It has held up well. I can see where a five speed would be nice but it sounds like the client may have Series regret. We've all had the guy who "just freaking loves that truck", until you let hum drive it and the hunt for third gear becomes the Safari of Disappointment. I've driven a 200 tdi five speed 88 and it's remarkable. Very pleasant. Perhaps a less antideluvian transmission would indeed help. A good set of noise and heat deadening mats if not already installed. Comfy seats. My new to me Exmoor "Defender" seats are much nicer than whatever were in there before. Springs in good shape? With the exception of the tranny, I'd be looking at comfort rather than performance.

Other than a chance meeting at a campground in the Badlands, I don't know much about the Rover.
We've had a nice phone chat about what he liked and didn't like after their several week adventure and this was just one of the concerns. I think the 200 needs some tuning, and the drive-line may not need a comprehensive refit if the more drive-ability is found. Thanks for all of the input!

Advance Adapters makes two adapters for the Series transfer case. I think this should allow for some domestic auto options.
