just chucking around a few ideas.

 

such as buying a tt block and upgrading the internals with high compression na pistons skimmed heads ported and flowed heads.

 

which is stronger a tt block or an na block :p

NA and TT bottom ends are exactly identical, except for the following parts:

oilpump, oil squirters and pistons (and less important, the exhaust manifold stud pattern is slightly different)

so you are saying the na's crank is equally as strong as the crank on a tt lump ?

yes, TT and NA cranks, rods, girdle and engine blocks are all the same.

Also I have heard from several sources, the socalled Nismo crank that can be bought in the US, is actually just a regular crank as well..

The only (proven) uprated crank available for the VG30DE(TT) is the one that is used in the strokerkit from JUN

 

one thing I forgot to mention in the list of differences in bottom-ends are the (piston) wrist pins.
