You will need ethanol or race gas to get into the high 400's.
The "stage 2" turbo's flow more air so make it easier to see high numbers on low octane gas.
If you are looking for a reliable 500, you should be looking at RB's.

All N54s have a forged steel crank. Earlier N54s had forged pistons. Later N54s and N55s had hypereutectic.
