After 10 years of prevarication, I've decided not to go ahead with dropping a M54 into my E30 cabrio so I'll be looking to dispose of the collection of parts that I've built up. Will need to fight my way into the shed for a stocktake, but basically:
All of the bits made by Dan - exhaust manifolds, steering linkage, pipework
The requisite diff and prop-shaft
Suitable sump, with a takeoff for oil temp gauge
Pair of engine mounting arms
E36 engine wiring loom
Regarding power plants there are two options:
1. 2001 E46 M Sport 3.0l auto as a donor car. Used as daily runner until 2 years ago. Fired up instantly a few months ago but has lost tickover (MAF?)
2. Similar vintage Alpina 3.3l engine/flywheel/clutch/gearbox in pieces (bottom end complete). Fully refurbished cylinder head. Alpina ECU. Original documentation with VIN.
If anyone is interested in any of this, please get in touch otherwise it's off to eBay

Merry Christmas to everyone in the zone!
