How is that "epic"? Its neccessary. Have you ever crawled under an S2000? The pumpkin is about the size of an R180 if that and is by far the weakest part of the car. Honda added a "CDV" (Clutch delay valve) on the 2004+ S2000s that slips the clutch on hard shifts to reduce strain on the differential.

I would love to do the R200 swap in my S... Nissan can build a rear end for sure. The R200 VLSD in my 240Z (from Z31) - took a serious beating and never quit. Unfortunately InlinePROs kit runs around $3K?, which doesn't include the pumpkin. Still, in a high HP car it'd be worth it.
