E30 diesel or s50

[Roysneon]

Did we get the M51 here in NA?

M51 from the e34 525tds would be the go. The electrics would be no harder than an M50 swap & the sump will be round the right way.

My brother in law had an e39 with the M51, and it was sweet - enough torque to be vaguely entertaining (even in a heavy e39) and returned 43mpg (imp) cruising at 80mph on the motorway.

Of course the M57 is better, but fabrication would also make it much tougher swap.

Which diesel? Early m21 is a direct drop in, late m57 involves a LOT more.

If you could get your hands on one of the diesels top gear used in their endurance race that would be sweet.

*edit*

I realize that was a pretty vague comment. It's from an episode from about 4-5 seasons ago, they took a diesel e36/46 to (bristol?) for a 24hr endurance race. Hammond crashed into a Mosler at night or something.

I've always fancied the idea of a diesel e30.. If you decide to go s50, I've got a few sets of s50 cams laying around

[tylernaugle]

Right now, I'm not quite sure which way to go. I have a s50 minus cams (got for free) but the engine was heated up and the guy replaced thw head and gasket but still had no compression and thought the block was warped...so I'd like to know if there's any thread with diesel swap information ( searched didn't see anything that stood out) or if trying to rebuild the s50 with m42 pistons would be better
