^Actually Porsche has been running 3.8L RSR's at Le Mans since 2006 and 4.0L since 2009.

I say they just make a special edition spyder cabriolet millenium speedster RS with centerlock Fuchs and call it a day.
Glad to hear from the real expert.

Thanks Alex,

Unless they stroke (which is a lot of reworking and money not to mention the way it kills the revability) to get to 3.99/.4.0 would still mean serious money.... And the lifetime would be compromised anyways.
