Found some pics of US spec 2.5 litre motor from VW Rabbit (6A, 150hp).
A Canadian bought the motor and stripped it down for upgrades, ony 1.8k miles old.
Chain driven double cam with dual sprockets, single hydraulic adjustable.
Does show Audi learned some tricks over the years...
Engine with loads of plastic:
Weird alu spacer:
Circulair exhaust ports:
Nice inlet ports:
Top deck view showing little squish and lens shaped bowl & squirters:
Piston with ceramic coated skirt:
Head with integrated housing for drive chain:
Close up of head showing water pocketing almost fully around combustion chamber:
Cam timing adjuster:
Top view of head. It uses a plastic rocker cover:
These heads use rockers:
This is the entire project thread showing what he fabbed. Guy is a welder with some skills:
