Looking for some advice toward installing a jeep 4.0 inline 6 into my Defender 110.

The reason I want to use the Jeep 6 is due to the fact I have one sitting right here in my Grand Cherokee with only 90,000 miles on it in perfect working order.

This is an utterly fantastic engine with a legendary reputation for reliability and low end torque with similar power figures to the land rover 4.0 v8, but without any of the liner issues.

What is the best way to put this engine in my Defender?

Should I swap the jeep automatic transmission and transfer case into the Defender?

Or is it possible to bolt the engine to the land rover gearbox? (LT-77 in my case) Obviously the bell housing would need an adapter.

Anyone done this swap before?

Many Thanks

This is all possible, it comes down to how much you are prepared to spend and your aptitude for mechanical engineering and design.

If it was me I would look at dropping the engine mated to a LR R380 gearbox to keep the drive from the gearboxes back stock (read easier to get parts for etc.) I would not put it onto an LT77 - I cannot stress enough how much I would not do this. You will tear it apart very quickly, especially if this engine has legendary low down torque, so in your case maybe the Jeep auto is the way to go, but work from the transfer-box position forward if you can.

As for mating them - you will want to become friends with a fabricator/machine shop who can produce accurately cut and and drilled plates and adaptors etc.
