Hi Walter,
Yes, he used the 42 mm header in stainless from Bernd. And no, this is not a Riechert setup in the picture. I built this fan setup 1989 because I wanted to fit a G60 charger to my 2 L and the only way to accomodate it in the engine bay was to relocate the fan. The steel plate in the front is 5 mm thick and bolts up to the four 8 mm threads in the block. The small pulleys on top are of a Peugeot 305 engine which has the alternator relocated from factory.
All that needed to be done next was making a bracket for the alternator to the block and making the moulds for the shroud. This is exactly what I`m working on at the moment, only with aluminium shrouds for better heat transfer. Fibreglass and carbon seem to keep the engine a tad warmer
The mods to the oil galleries included getting rid of the original plugs and then
drilling them (galleries) out on a CNC machine @ AMG ( the same machine that machined my caliper brackets). He wanted the most possible oil supply
( volume) and even though they are bigger inside the pressure is higher too through the big geared pump and special oil pressure control valve. As for the turbo oil return, it used to get sucked out through an electric pump but got included in the dry sump system now due to that electric pump failing (temp).
The mahle 103 mm piston and cylinder set is top notch as you probably know and a lot of guys drive them for years and years without problems. One of my friends rebuilt his engine after 7 years and all that was needed was a set of bearings and a gasket set, and yes he drives it regularly and hard.
The 6 stud setup is from PTP and the cylinders have had 2 small sharp lips machined into the top, looks almost like 2 small hair. Hope I didn`t bore you to death
