Series 3 109 engine conversion BMW M57 6cyl diesel

Hello there to all,

Long time owner of a 110 Defender CSW 200tdi factory standard.

New to Series landies.

Have a 2006 single turbo E53 BMW X5 in her last year of service due to corrosion. Engine sound.

Question- is there anyone on here that has fitted an 6cyl M57 engine to a series 3?

plan at this point is manual BMW gearbox mated to BMW engine, keep BMW intercooler and radiator. BMW propahafts with landy flange fittings welded on their ends running off of LT230 with disco / defender axles converted to leaf mounts.

Familiar with mechanics, repairs, welding. Hate electrics. Hate plastic trim.

What's the power output?

Circa 200hp 400nm

Diffs and halfshafts?

I would imagine it would be a lot of work and will lose its classic status and possibly need an IVA.
Interesting project though I should think.

I can't imagine it would take that much power though

Proven solutions HD flanges half shafts pinion etc

More interested in seeing an existing conversion to work out the position of engine and box relative to bulkhead, gear lever situation, rad / intercooler versus front series grill placement.

Don't worry, it'll take it. Also drive on light throttle most of the time.

Yes exceeds on a points basis unless keep the original axles and steering. Actually that may be an option come to think of it with heavy duty components. Will look into that further thanks.

Also fails if you modify the chassis in any way.

You're well ahead of me on this, I was just querying for my own learning.

Sounds a great project!

Excellent, so proper mounts for box and engine in order

MW machines have done a conversion on a Defender.

no idea on the series though, why the M57?

Seems like it's OK to move engine mounts and gearbox mounts but not cross members or out riggers.

Start with a six cylinder registered vehicle, ideally a scrapper, buy a new 6 cyl chassis. That should get you a long way there. Much more space.

Just buy a Jeep.

Wouldn't say ahead , we are both building a picture in mind

Ten years ago if I'd brought this up on here I'd have been banned already lol

Interesting, wasn't aware of 6 cylinder series, will look into that thanks

Noted though not in memory from in depth reading many years ago. Things may have changed. Dependent on position for gear/ transfer levers, and space behind the front grill, it may be possible to modify mounts to suit the existing chassis setup.

This is where it would be really handy to find someone who's got even a rolling chassis already setup
