I have one of the adapters from the BMW to the R380 on it's way over.
A friend has a BMW repair shop with the M54 and M52 engines lying around so wanted to see if the P38 R380 adapter will work with these.

Thought the same thing. It would be possible to use remote Booster(s) to keep power brakes which are paramount.

Nice. Looks like we may have started something.

You might prefer the 2.3 i4 Ecoboost.

In South Africa, I've been told the 2.8i Defenders are a bit of a legend. And still fairly sought after. In my research I've found it's fairly common to find 2.8i Defenders with 200k to 300k km's on them and they're still using the original engine. Now that is saying something.

300KM is only 180K miles. In OM617 terms this is barely broken in when the engine will run well over a million miles... but not terrible for some petrol engines.

The 3.0L M54 I'm putting in mine is more powerful than the 2.8L M52 (225 hp @ 5900 rpm & 221 lb·ft of torque @ 3500 rpm vs. 190 hp @ 5500 rpm & 210 lb·ft of torque @ 3500 rpm.) The Rover 3.9L V8 is rated at 182 hp @ 4750 rpm & 232 lb·ft of torque @ 3100 rpm. If we look at this graph from BMW that compares the power of the M54 to the M52, we can see that the M54 acheives about 195-200 hp at the V8's peak at 4750 rpms. So discounting the V8's slight torque advantage, it's a more powerful engine. Plus it's much more efficient, very smooth, and probably weighs less (375 lbs vs ~440lbs?). Better all around IMO. Here's a Land Rover 3.9L V8 power graph: Engine weight data: BMW M54: http://www.usautoparts.net/bmw/engines/m54.htm Rover V8: http://www.pistonheads.com/gassing/t...Marquis+%2BRex

Don't get me wrong... I love Beemer engines... I've had several bikes and cars... Loved my 135i convertible

But... 4x4s generally want low end torque... The m54 is a different engine than the 2.8 that they originally used...

I had heard that the LHD wasn't possible due to some configuration show-stopper, so I'd be curious to hear about a real world experience for sure.

As you can see the m52b28 (version that came in defender) was a very very different engine than the m54.

No torque at all until you are over 3000 and you really want it around 1500-2000... Really a smidge lower than that...

Robert,

Your not comparing apples to apples...or even stock drivetrains for that matter! I mean, yes, it's only 180k miles......on a stock Land Rover drivetrain.....in Africa.....

Hang on a sec....now that I think about it, that actually is fairly impressive for a petrol engine that's stock and only had to have its oil changed......and nothing else.

The "mortality" rate of the Rover V8 has always been quite high, and those that do make it over 100k miles usually haven't gotten there without having a fair amount of work done to them in order to keep them "alive".

By all accounts, the BMW 2.8i is far superior in longevity compared to the stock power-train found in NAS Defenders. I guess what I'm trying to say is; if I were given a choice between the two petrol motors to drive across country (or across the African continent) in, I'd hands down take the Bimmer 2.8i over the Rover V8.

That said, I do get your point though.

Yeah, the M52b28 was kinda weak sauce. I agree with you that it wasn't the best choice for a truck. The M54b30 has way more low end power. BMW developed it for the X5. BMW states, "The increase in displacement allows the engine to kit the X5 All Roads vehicles while still meeting the demands for power and performance." While the X5 isn't exactly a truck, if it works out well for that then it'll probably be fine for a Defender 90.

Here's some history on the Defender 2.8i:

"Interestingly, when the development of the 2.8 went ahead, LR sent out NAS Defenders for the prototype builds, as it was thought this engine would be popular in USA too. Other items, like all all the main reasons Defenders aren't sold there now, stopped that idea though and the production versions are all from the normal SA spec CKD vehicles built at the LR factory in Rosslyn." From: http://www.landroveraddict.com/forum...threadID=60760

This is true from what I can tell, as the Defender 2.8i has a NAS chassis based on the parts diagrams. The same guy who posted that also refers to a "3.2 version." After a little more digging I found out that was a racing Defender built by a guy named Cliff Barker. It would have had a S50b32 out of a Euro E36 M3. Here's a picture of it:
