The engine: It's an old but never used 9,7:1 325ix. Unfortunatly the seller "forgot" to tell me it was for a 325ix and not the standard I thought I was buying.
There are some differences between the standard M20 and the 325ix. Some are easy to fix, like the ix uses M10 instead of M8 for the support bracket, uses a different bolt pattern for the oil pan, dipstick at the rear, etc..
The main problem is the relief valve. The ix have integrated the relief valve into the oil pump and therefore don't have a thread for the standard stand alone relief valve.
Standard M20 (relief valve goes to the right):

The block is lowered 2,2 mm, Schrick 284/272, adjustable cam sprocket, Alpina B3 eprom, Eberspächer non-catalyst exhaust, used eta crankshaft and con rods.
It's what they call "variante III" at e30.de.
