Hey guy's, I've been wondering what the hell to do with my thirsty XJ40. It's sitting around feeling sorry for it's self and I need a plan. I'd like some more power and she needs to go on a crash diet at 1800kg! My question to you knowledgeable folk is, if I decide to stick a big old turbo diesel under the bonnet which is the best one to pick? I'm thinking it'll give me the tourque I need to get her fat ass rolling and I can get some semblance of economy too. The only problem is the only diesel I've had was an Audi A4 with a 1.9tdi pd engine in. So I don't really know what's out there. It obviously would have to come out a rear wheel drive car to start with and I want something reliable and economical with some decent power. The Audi was fab doing 60mpg with 130bhp and 300ft lbs of tourque, a remap would probably see it close to what I'd want. But it was FWD and there's probably a better choice anyway. What are your suggestions? Here's a picture, just coz 😍  |

OK, my least favourite version of the XJ's is the XJ40 but I can't understand why on earth you'd want to put a Diesel in one?? Unless you're delusional you'd have known you were taking on a thirsty car? Part and parcel of the XJ experience for most was the sedate, quiet motoring with power & speed on tap when needed. Why on earth would you want to ruin this with a clattery knocking smoky lump in the name of frugality??! (Not to mention the enormous amount of work that would be required to facilitate this conversion).
Sell the Jag to someone who will appreciate it for what it is and buy a comfy, clattery, Audi or Merc Diesel.

I’d go for an OM605 you can get the same power it’s shorter block and lighter and it sounds cooler. 👍🏻

How much do you want to pay, do you want a fully mechanical diesel or would an ecu be ok?
Mercedes OM606 is a good engine (got one in my Land Rover), tuneable, and can be had with auto or manual once you find the bits. They came with an EDC pump so need an ecu to control, and I think it was well integrated into the host car but I believe there are aftermarket controllers available. Mechanical pumps can be swapped in, but those are desirable, rare, and thus pricey. Standard comes with a front bowl sump, but rear bowl sumps are available from later engines, though again since those are sought after for 4x4's etc they're also getting pricey.
BMW have a good selection of inline 6 diesels too with a variety of transmissions and I believe some of the older versions are mechanical injection? Not sure how much effort would be needed to get an ecu controlled BMW diesel to run out of the host car?

Got a bmw 2.5 six pot out of a p38 here with loom ecu etc etc if you’re interested (and anywhere near norfolk, or willing to travel?)

]The only problem is the only diesel I've had was an Audi A4 with a 1.9tdi pd engine in. This will be of no help to you at all I’m sure but the 1.9 TDI VE/PD engine is my favourite Diesel engine! There are a huge amount of swapped PD powered cars and many have managed some impressive power. That said I have no idea if it would go well into a jag. What about a 300tdi or TD5 from a Land Rover? I’ve seen some pretty pokey (for a discovery) Discovery’s with the TD5 engine. |

BMW 3.0D, or an OM6** of some kind, plenty of variants, dropping in a standard one would more than suffice if you choose a modern one.

Surely if weight loss is a priority, the last thing you want is a heavy diesel turbo lump replacing the alloy straight 6  But having read through the suggestions above, the TD5 sounds the most appealing. They make a good noise, shouldn't be too difficult to source and are fairly electronic lite from the donor vehicle compared to the Mercedes or BMW choices  |

Remove the electronic pump and fit a manual pump and the only electrical cable you need to run that engine is power to the starter they work without glow plugs. TD5 has a wiring loom going through the rocker cover that leaks oil in the the ecu. |

I'm somewhat biased but a Cummins 6BT fits Jags (just)   |

I'm in the throes of fitting a td5 into my rrc, its quite a tall engine, but the biggest issue I've found is having to get the ecu fitted with an alarm emulator to stop it from immobilising itself when it doesn’t get a signal returned from the body ecu.
I'm not sure if you can just swap the injector pumps on these like you can on a tdi, its a 5 pot of course, i did hear that if you use a defender ecu it reduces some of the problems I've got, but I'm sticking with my ecu since it was a complete running td5 disco before i started!

On here things get changed because it's different, challenging and fun. BTW the XJ40 is the best Jag in my opinion. |

Hi, thanks for the info, I was also wondering about how integrated the engine management would be. I'd like to find something that I can use the original engine ECU with, like you can do with some other cars. I don't want to spend a fortune and aftermarket ECU's can be so I might have to go mechanical injection depending on what I can find. |

They make a good noise, shouldn't be too difficult to source and are fairly electronic lite from the donor vehicle compared to the Mercedes or BMW choices Haha, I get your point. It might be wise to compare engine weights from what ever I choose. I recon I can lose a couple of hundred kilos out the body and interior though so hopefully that will go a way to offsetting it. The aj6 is still bloody heavy! The TD5 sounds good from what you've said it gets complicated and above my head when the ECU is too tied in to the original car. |

Touareg / Phaeton 5.0 v10 or an Audi Q7 4.2 v8. Probably fairly complex electric wise but the results would be worth it I think.

My apologies, I hadn't realised you wanted to swap out the engine because it would mark your car out as 'different', your intro read like you just don't like the fuel consumption, (it's a Jag - Duh!) I don't dislike the XJ40 it's just bottom of my XJ saloon shapes list, I don't know many Jaguar purists who are overly keen on that version, (yours looks very handsome and sound by the way). There are a lot of people who use these forums who enjoy classics / retros for what they are - not just modders. |

That has peaked my interest, let me do a bit of research on the engine and I'll drop you a PM. 😁 Someone on here has already done it into the shape before the xj40. But as the front suspension is about the same it’s more or less the same swap. The engine is an m51 btw. |
