Range Rover LS Swap I had seen some posts here or there on this...has anyone on Tech completed this swap? I found an Australian site that has some conversion parts, which will help, but I still have a lot of unanswered questions before I commit to this. I was looking to use either an LS1 or 5.3L with some mild upgrades and refreshing and a '96-'01 Rover (auto trans). I'd like to keep the 4WD but it is not crucial. Overall goal is to have the simplest and most reliable setup.
1) There are parts to adapt to the factory trans, but I was wondering how the trans is controlled and whether this is an issue with an entirely different motor and PCM.
2) Will this trans be able to hold up to the extra hp/tq, especially if I am towing (open trailer with Camaro racecar)?
3) Is there any way to connect the transfer case (4WD system) to a GM trans, and if not...is there any issues to not doing so besides the obvious loss of 4WD?
4) Any way to get the factory gauge cluster to work? If not, could I drop in an old F-body one or am I stuck with building my own cluster out of Autometer gauges or an expensive Racepak?
5) Does anyone know what oil pan and accessory drive setup is preferable? I could figure that out if need be, but of course it would be nice to know ahead of time. Looking to stay with factory parts if possible.

I just found out the answer to the first question more or less, the ZF 22 HP is electronically controlled, so I don't know if there is any way around switching to a GM trans. I guess I will just have to look into whether I can get a 4WD 4L60E to mate up to the transfer case or ditch it all-together and go RWD without causing some unforeseen disaster.

That's pretty much what I just said...I just hope it fits. The ZF trans is pretty small from what I hear, so it would stand to reason the tunnel is small too. I just emailed a guy who makes adapter plates for the Range Rover transfer case for other GM transmissions, not sure if he can handle a 27-spline unit. Transfer cases and 4WD is definitely outside my comfort zone and current knowledge.

Update: found a company that does adapters for the Rover transfer case to a TH400 (Marks 4WD). Since they both have 32-spline output shafts, I might be able to run a 4L80E. Knowing that I am going to be towing, this trans is preferred over a 4L60E anyways. So now I just have to sell one of my other projects and pick up a Rover, I should be able to figure out the rest as I go along.
Sounds like a cool project. I have thought about this one in the past.
What year range rover do you want to use? Also, why a range rover... any reason besides the luxury appeal? (which is not a bad reason at all)

96-01 but preferably 99-01. Always liked Rovers, just never the motor and electrical gremlins. So it is an attempt at best of both worlds. The company that makes the adapter says no dice on a 4L80E, which sucks. A 3.54 rear gear and only 3-speeds means it would scream on the highway.

This might be a stretch, but are the Turbo 400 and 4L80E tail housings interchangeable?

Just wanted to throw this out there.
Why not run a manual GM transfer case with the 4L80E?
Chances are neither of the driveshafts will be the proper length anyways, so you'll probably need to have them made.

more info there is enough clearance with the pan as it is. these guys are supposed to have a kit for just the engine to use the original borg tranny or a kit to use the 4l60e. they will have the engine mounts as well. I believe the intent is to use electric fans versus the mechanical fans. I purchased a wiring harness from speartech that was $1300 with computer and all and according to these guys thats all the parts you need for the conversion. I would think if you go with the 4l60e tranny option you will have to have a special drive shaft made.

Yeah you definitely will need a custom driveshaft, the Aussies told me as much. GM transfer case might be an option. My buddy said the TH400 and 4L80E are the same tailhousing bolt pattern. I wouldn't mess with the Borg Warner, sounds expensive to build and not the strong once it is. I'm game for a 4L60E as well, but was considering the 4L80E for more durability with towing and for ease of install.

the 4l60 is good if u put a kit in it. and its a heck of a lot cheaper because everyone bailed on them. the 4l80 is good out of the box I feel its just more about moeny and knowledge but yes due to the shaft being thicked and heavy duty it is far better than the borg tranny. I believe that they are a 1/4 in in length differnce so its not to much of a headache to install

Ended up with a 4L60E and made my own transfer case adapter. Problem with these is the offset front AND rear differentials, which rules out conventional transfer cases that came behind the Chevy transmissions.
I had to make everything myself, but it's worth it. EAS, HVAC, etc all work perfectly.

Discovery II LS1 Swap Anyone with more information on the how to wire the LS1 into the Discovery 2?
Here is the setup that I am planning on going with:
Engine----------LS1 5.7L.............300+HP
Transmission---4L80E.................Up to 440 HP
Transfer Case--LT230.................? Would like to know
Adaptor---------Marks4X4
Differential-----Land Rover..........? Would like to know
I have purchased both the wiring looms for the Discovery 2 and the LS1 motor and will begin to review to ensure that I can mate both together.
I want all of the original gauges in the car to work along with all other accessories. AC, Odometer, etc.

Many people have swapped GM engines and transmissions into land cruisers for decades using the toyota transfer cases with an adapter. You can get adapters to mount basically any GM transmission to the various land cruiser transfer cases. You rarely hear of transfer case problems in those swaps.
