Other Engine conversion

Morning everyone so I was wondering if its possible to install an engine conversion on a Discovery Sport, an M57 engine springs to mind, but this engine may not be suitable. Obviously there isn't really much point of an engine conversion on an early 2.2 Discovery Sport..
However, this could be worthwhile on a later 2.0 model if only to avoid the inevitable (I.e. some form of catastrophic engine failure). If an M57 wouldn't be suitable does anyone have any suggestions about what engine might be suitable please?
Any thoughtful comments welcome, if your thinking what's the point of an engine conversion then this thread probably isn't for you and I politely ask you to look elsewhere. Thanks in advance James

It's very unlikely that anything other than the original engine will work. The easiest conversion would be to roll back to the 2.2 DW12 unit from the early DS.

Any kind of engine conversion would hideously expensive however.

Many thanks @Nodge68

Well that's a shame. I was hoping to bag a destroyed engine DS and have some fun with it!
I know engines aren't cheap but is there really no way around this? Is it because a new gearbox, wiring loom and other things will be needed?
What sort of prices are we talking?

Pretty much anything is possible with time & money.

However, I'd suggest if you are needing to ask such a question, then the answer realistically is no. Unless you are wanting to spank £20,000-25,000 for someone to have a crack at it, then it could be a yes. But a tentative one.

Other engine swaps are probably much more feasible but you would likely be treading new ground no matter what.

Anything is possible, but modern vehicles are almost impossible to carry out engine swaps, especially so if the engine is from a completely different manufacturer.
There are so many differences, that the engineering alone would be a serious challenge. The electronics on the other hand would be basically impossible to get working. If you used a BMW engine, the BMW ECM would be needed to run that engine. However the BMW ECM will need to talk to the rest vehicle over the CAN. The issue comes that the data on the CAN from the ECM to the vehicle won't be understood by the vehicle modules, and vehicle systems data to the ECM wouldn't be understood by the ECM.
Engine swaps before the 90s were purely mechanical, now they involve both mechanical and electronics, the electronics being much harder to re-engineer.

A conversion like this as a one off would be much more expensive than the value of the vehicle, so would be a pointless exercise.

It's potentially possible to use the PSA DW12 from the early DS, which is the way I'd go if I was wanting to re-engine a DS.

Of course you could just get a DS and maintain it more regularly, reducing issues with the engine.

Ok many thanks @300bhp/ton and @Nodge68, much appreciated.

A shame as I like a DS. I'll stick with my early 2.2 then, which recently has been out of action, see other posts on here.

Looks like it's a Defender then!

Are you in the UK and have you ever taken an engine out of a vehicle before or done an engine swap?

I only ask, as I'd assume anyone who has worked on a vehicle and done engine swaps (even if just doing a clutch or a like for like engine replacement). Would know what is involved in fitting an engine.

I really do mean this to try and be helpful. An engine swap is a pretty major thing to do. If you have time and experience, then it is amazing what engine conversions there are out there. But they will normally need quite a lot of R&D and fabrication, unless there is already a scene and market in doing said swap. But even then it can still be a lot of work and usually not exactly plug & play...

On a basic level, does the engine even fit in the engine bay? If not, can you make it fit? If it fits, is there room to have things like radiators, intercoolers, pipework and all the other things you find in an engine bay normally?

I have no idea on the Discovery Sport, but as a transverse engine platform with small engines, a straight 6 sounds like a large engine to physically fit.

Does the engine then mate up to the existing gearbox?

If it doesn't, can it be made to fit with an adapter? Do such things exist or would you require a one off bespoke one being made?

Can the transmission even handle the expected power/torque of the intended engine. Are there different transmission options? Can they be made to fit the vehicle?

Considering the Discovery Sport uses a complex and advanced 4wd system and is a transverse engine, I'd guess transmission options might be hugely limited.

Can you get the engine to play ball with the rest of the vehicle? Does the BECM need inputs from the engine in order to work correctly?

If you aren't planning on doing the work yourself, this would likely be a major project to pay someone to undertake. As they will still have all the same questions and require answers to them.

Lots of engine swaps will be based on engines from the same engine family as the original or something done by the manufacturer at some point on that platform or using the major components.

Depending on which country you are in, there may also be legal restrictions and limitations on what you can or can't do.
