[Supras] mk3 block differences?

[Dave Henry]

We've run a couple of bone stock 2jzge's to 8200 repeatedly (every weekend) 
without issues. Thats short bursts (9 sec or so), not extended periods of 
time like when you are roadracing. Granted thats a far cry from 9000. :-p

The difference in the sound of the engine at the stock 6800 rev limit vs 
8200 is amazing.
