of oil plumbing parts, some unique to German cars.   The Mocal/Spal fan/AN
fittings/adapter plates and thermostats are available here to create an
effective oil cooling system...Their site is somewhat awkward and be sure
to page around to find the section on Porsche cooling, as those outline
some systems, and some specific adapters from Metric to AN, etc.

   Be diligent with the execution of your install, if you add an oil
cooling system.  Try to design it so that should any part fail, the system
reverts back to stock.   .Mount the heat exchanger and all the lines
carefully and isolate them from damage and vibration.

  I'd think that the WBX motors would greatly benefit from an oil cooling
system beyond what they have now...judging only (my motor is 'other than'
WBX)  from what I often read about the oil warning lights coming on after
hard driving, and people suggesting heavy oil weights to counter the low
oil pressure issues.  I know from careful monitoring of my own motors,
usually all equipped with oil temperature and oil pressure gauges, that the
temperature and pressure of you motor's oil are very interrelated..20 or
30F oil temp difference can mean 10-20psi oil pressure difference.
