BMW S54 engine

The BMW S54 was a high performance engine with these features:

1. Increased cylinder bore to 87 mm (from 86.4 mm) for a new total displacement of 3,246 cc (from 3,201 cc)
2. Modified camshafts
3. High pressure Double VANOS continuously variable valve timing system with faster operation at high rpm
4. Increased compression to 11.5:1 (from 11.3:1)
5. More advanced BMW/Siemens MSS 54 engine management control
6. Finger-type rocker arms for reduced reciprocating mass and friction
7. One-piece aluminum head casting for lighter weight
8. Scavenging oil pump to maintain pressure during heavy cornering

An unknown source broke the entire engine down and laid it out carefully for us to enjoy. Now we just need someone to label each part for our didactic purposes.
