<x-flowed>man, after years of stagnant development of VW  hp parts, there is a ton 
of new stuff out there!  the list in the subject line i just pistons and 
cylinders!  with these, the development of CNC ported heads with real 
cooling fins, aluminum cases and modern fuel injection, it seems that 
180-190 daily use HP in an air-cooled VW is within reach!  ;)  that 
makes me drool!

I have an 'old skool' part question for the experts out there though... 
what made the NPR pistons and cylinders run cooler than the old forged 
mahle/cima units?  Were the cylinders made of a different material?  I 
know the pistons are heavier but since the NPR 90s were only .50mm 
smaller than the 90.5s, what else helped them?  I know they run cooler 
because i have had the 90s and the 90.5s in the same longblock with them 
being the only change.  Thanks for any opinions or enlightenments!  And 
remember, "Keep the dirty side down!"
