Porsche GT3 - Titanium rods 8000+ redline Acura NSX - Titanium rods 8000+ redline Ferrari F360- Titanium rods 8000 redlinethis would lead me to believe that less reciprocating mass has a lot to do with it.. but also tight engine tolerences I'm sure... but the VG is no slouch AFAIK All of these cars, and I know there are more, run sub five second 0-60 times on all motor... there is noone that can convince me the Z cant do the same... The work on the motor and heads to get this going would probably be around the same ballpark as say a NA to Sport 500 conversion..... hmmmmmmmmmmmmmmmmmmmmmmm
