It should: I can't see anything that would be a problem on a left hand drive European model. A right hand drive model might have a couple of tight spots with the manifolds, but it should still work. I'll look into it further to make sure. Might have to trim an accessory bracket slightly. With a 4.0, it is likely you have the 4HP22.

In other news, I did another 200 mile trip with the prototype this weekend. Everything went well. Lift kit is settling in. It really helped the ride quality.

Good to hear

I'm taking this project very seriously. Purchased a 5.3 LM7 today together with a 4PH24 as I confirmed with the mechanic that my D2 has a 4HP22. Hopefully, I'll be the first to do this conversion in Europe.

Be careful with the selection of the 4HP24, as there were different models with different torque converters. This currently works with the 'medium' torque converter on the 03-04 Discovery 4HP24. I am checking to confirm if the Range Rover P38 4.6 Bosch 99-02 4HP24 will work as well. Also be careful with engine choice. Some 4.8s have the long-crank that is incompatible.

While I appreciate the enthusiasm, I would recommend and caution that everyone wait before jumping on this. While everything has been going to plan, and we intend to release the kits in the future, unpredictable things and delays can arise. Until I am confident in reliability, it would not be fair to release these kits. I will release much more details about recommended engine choices, etc in the near future.

In Europe most of the 4HP24 come from the p38 range rover which will not fit to the D2 without modifications. I was lucky to find a 4PH24 from an American market D2. Also, finding an LS engine in Europe is no easy task so I had to take this one. If things do not go as planned, I can sell them.

Update: I looked at the engine I found on craigslist and I wasn't happy with it. I think it had been in (improper) storage for a while and I was a bit worried about it's internal condition. I'll hunt for another.

On a different note, I have been working more on the electrics and I am confident we will be able to support Gen 4 LS and Gen 5 LT engines in the near future. There will be a little more to these conversions and they will be a bit more expensive. However, there are many low, low mile Gen 5 engines in junkyards. The local LKQ has 5 5.3L L83 engines with between 5k and 40k miles for just under $2k. It's a bit more than the Gen 3 engines, but the mileage is so low that it might be worth it.

Another interesting possibility that this opens up is the GM LV3 4.3 V6. This engine is basically the Gen 5 LT less two cylinders. It's all-aluminum and makes 285 hp and 305 ft-lbs, which is nearly identical to the Rover 4.6. The electrical, etc. is the same as the other Gen 5 engines. These are also plentiful; I have found them as low as $900 with around 40k miles. I think these would make a great build option. They weigh quite a bit less than the V8s.

Gen 5 will come with some more issues, like different motor mounts, more complicated electrics, etc. so it will be a little while. We're still focusing on Gen 3 for the time being.

Hmmm.. LV3 4.3 with turbos?

This brings up something else i was thinking about the other day.. Since you are doing the wiring for an OEM GM electronics, how hard would it be to do a standalone setup?

:dunno:

We've been looking at using the LV3 for a buggy project since it's under 400 lbs. Turbo LV3 would be cool. I don't think the aftermarket support is quite there for the LV3 yet, but I think it will be soon.

Our electronics setup is adaptable. With a bit of fiddling, we should be able to accommodate an assortment of engines. A standalone electronics setup is part of the plan. The LS was just the logical place to start because of availability and price, etc. Long-term, after we get the LS working well, we'll starting looking at other options including diesels.

Makes total sense to start off with the LS platform for something like this no doubt! I've been watching a lot of Mighty Car Mods as of lately (Yep, i know) and they just throw a Haltec in everything and go on their merry way :dunno: Would be cool do a truck of sorts rather than some 240 drift car etc :dunno:
