How much power does the 4.8 put out? Also does the price include an upgrade drivetrain.

 

I'm not sure how much it puts out but they said they buy the engine, rebuild it in house then install everything and it will work with the existing transmission and control units. I know they have one with the 4.8 and have logged over 9,000 miles on it. They said that was for the engine conversion and it would be closer to 10k to $10,500 after taxes and everything. They did say the 4.8 is cheaper since they are more avaliable

 

mounts and adapters are already available to mate an LS to the zf. The secret sauce is running the LS on the Bosch engine management.

 

That's the easy part.

To me, the hardest part is the mounts and the adaptors are within spec. If you are referring to our friends from the land of the kangaroo, they themselves will not confirm it will fit.

Sorry, meant the trans adapter

Their transmission adapter they say themselves will not work in our trucks.

 

This would solve the transmission and engine mounts issues: GM 6L80 Automatic to Land Rover / Range Rover LT230 Transfer Case.

Also, would open up other LS engine options but I think you would have to upgrade the diffs, axles and cv joints.

 

Fine, I'll bite.

Yes, it would make the psychical swap possible. But to run that engine and transmission, you need to run parallel ecu's to keep the BCU happy. ECU, Trans and BCU need to see their respective signals, otherwise it wont start and the cluster wont work. You will need to run the GM ecu and transmission ecu to run that engine and transmission combination as well. Charlie will back up my words, we have done the research, spent 6 months searching parts and read somewhere around 200 pages of forum information from the few people that have successfully pulled off this swap. Its not for the faint of heart.

Easier would be what trailhead has done. Swap the block, use rover electrics.

 

Agree with you.
you could run the ashcroft standalone trans controller but it would create other issues. Running on the Rover electronics is the way to go.

Mounts are a solved problem though. There's definitely a knowledge gap on why the engine to zf trans "wouldn't work". In fact if will bolt up, I think folks are just over thinking how to control the transmission.

theres a guy in San Diego that also makes adapter plates and mounts. He's the guy that started putting ls's into defenders. I've been planning on setting up a shop to do it here in the Seattle area, just haven't got round to it yet.

 

I thought in the discussion on Discoweb there were serious concerns of passing inspections in many states. The discussion and statement says the engine and other management systems will play well together, but I'm not sure.

Don't get me wrong, it sounds like a great idea, but there seems to be a bit of unknown based on what I read.

Frankly, for that amount as a turn key solution, it seems more logical/safer just to get a redone Rover 4.6. But that's me. The mpg and power gains are nominal based on what I read, and the redone 4.6 should last a good long time and was designed from the factory to be in there. Maybe I'm just lazy, but it seems when you piece part a frankenstein machine together with one (major) component that much better, you are neglecting the other issues that could come up.

In other words, if the end goal is a more reliable and efficient and readily available motor, but it doesn't play absolutely perfectly with the existing stuff, you are continuing the legacy of the Disco being something that constantly needs to be monkeyed with. I guess my philosophy is a multi-billion dollar OEM with teams of engineers know how to make it all play well together better than a few individuals. Again, I don't want to dump on the idea as options are always good, but this one seems a bit far fetched to me.
