Part 2 of the Disco conversion is on YouTube. Interesting that the engine mounts for the new engine are meant for a Defender...

Yep, the plan would go exactly like that!

2007 Defender 110 Puma 2.4 DCPU Stornoway Grey

Cummins has a series of videos covering this engine and installation considerations which makes for interesting watching.

https://www.youtube.com/playlist?list=PLqb...EziUeYNT0-

This series of videos makes for very interesting watching even if you're not considering an R2.8 installation since it explains very clearly many of the design factors for modern turbo-diesel engine installations. it is an excellent turbo-diesel "primer", worth watching for than alone.

On the face of the information available sofar it would be a very easy installation indeed to put one into a TDCi in place of the Ford motor, almost turnkey. The R2.8 is designed to mate to a Getrag 5-speed manual transmission, so might even bolt straight up to the 6-speed if Getrag have used a standard configuration.

There is number of ways in which the care and forethought put into the design of the R2.8 really impresses me, and I like the fuel filter head with the built in manual priming pump too, why couldn't LR have done something similar?

I don't know if it would be legal to fit one in this country due to emissions regs, but it has EGR and Cat so might be OK for something that started life as a 2.4. Any know the score on this?

I'd be interested in something like this when my 2.4 TDCi gives up the ghost (hopefully in many years time).

A 6BT is massive overkill for a Defender, they're the sort of thing fitted to a 7.5t lorry. 4BT more appropriate but it's still a 4l lump of an engine. For a stationary application I wouldn't mind one as they last for every but IMO too much weight for a Defender.

The 6bt isn't that big..

It's factory fitted into 1 ton Ram pickup trucks and slots nicely into a Defender engine bay.

That said... this cummins 2.8 crate engine would be an excellent repower solution and will probably not overstress the standard Defender drivetrain.

It seems to be about 20% lighter than a Puma engine, with 20% more torque and power. I suspect it might be pushing it a bit on the driveline.

Going by what is said in this link the R2.8 seems to be made of chocolate.http://dieseltoys.com/4bt-engine-conversions.

In case anyone is missing the point, the R2.8 is a NEW 2.8 litre 4 cylinder specifically for REPOWER applications - as said by BlueST.
Cummins sell it as a kit ready to fit, it can even run in the create with fuel and power connected.

Petersen's 4 Wheel magazine have already fitted one in Range Rover Classic, and a few Jeeps.

It is not a big, heavy 4BT or 6BT.

You've got to wonder though about the viability of fitting a diesel engine with today's backlash against all things Diesel.

I also agree. Living in the EU as I do, near a city that has already brought in a part-ban (Lyon), near a country with ever-stricter emmissions laws (Switzerland) and in a region with notoriously high levels of pollution (the Alps), I think the anti-diesel sentiments will only get stronger and become more of a burden on big, old 4x4 diesel cars. So if I was ever going to go through the effort/cost of fitting a brand new engine, that is not a like-for-like swap, I would now be seriously considering the JE Engineering Ford 2.3l Ecoboost upgrade. Better emmissions, quieter, cleaner, more fuel efficient, easy swap, half the price of a V8 and still between 300-350bhp. I'm giving it some very serious thought as possibly the best future-proofing option to keep the beast on the road for the next 25 years

Sounds good, and much cleaner, which should help it in all manner of areas.... not cheap though.

2015 Defender 110 Puma 2.2 XS CSW Aintree Green

Diesel Toys - seriously, who is going to spend $28 to $42k repowering a pickup that's likely to be already 8 to 10 years old?

http://dieseltoys.com/tundra-diesel

Just been reading too that premium diesel estate cars (Merc, BMW) are now only expected to retain 30 to 40% of their initial value after 3 years. Partly down to people wanting SUVs, but mainly due to concerns on where/when diesel use will be allowed in the future.

I find myself coming back to this thread - and the Cummins r2.8 website - increasingly frequently, as I consider this motor for a future project.

Does anyone know of a r2.8 Puma conversion?

I saw on an American site that they think the Puma platform is not as suitable as older Defenders because of the MT82 transmission (in Defender configuration) being on the limit given the engines torque output.

Another big question mark as noted by Blackwolf is the compliance to EU emissions standards. For sure it will be better than the TDCI, but if Cummins don't homologate it, its a moot point.

Just some thoughts from a guy who was pondering putting one in his Defender.

I stopped watching at 2:25....

Anyone who is comparing a 300TDI motor to a R2.8, and is wary about it being "made in China" is not thinking clearly....

I understand what you are saying, but I think the "made in China" thing is distracting from the point he is trying to make. That is, noone has done a lot miles with one of these engines and previous related engines have poor reputation. They may be fine, but he doesn't want to be the one to find out if they aren't fine.

In the second vid, he is coming round to the idea of a petrol engine. These bids are just thinking out loud. 2007 110 TDCi Station Wagon XS
