52 L322 Needs new engine

Guys

As the engine is a 4.4 v8 BMW derived lump , could a replacement be sourced from a BMW and does this then open the way to an e39 m5 lump ?

I also heard the engine ended up as a twin turbo Bentley is this correct

Thanks for your help

'Tis only a guess (please note!), but I imagine that while the base engine is the same the sump, oil pickup and things required for more extreme angles (and 4WD hardware??) may be different, plus the viscous fan drive and maybe some ancillaries.

But depending on what's gone wrong with yours, perhaps you could take all that sort of thing from your existing engine?

Happy to be corrected of course.

A thought occurred to me this morning would the X5 4.8 fit

AFAIK, the block is the same. However, the sump is significantly different to accomodate the 4wd gubbins.

Yep, and it's down on power but up on torque from the BMW version, plus is designed to get somewhat wet and times, along with operating at odd angles.... putting a standard 4.4 in there would be.... interesting!

It was briefly in the Arnage, but it was rubbish and nobody bought it. The 6.75 was quietly snuck back in shortly afterwards.
