In my stock block Honda S2000, it's comp is 11:1 and I run 35 psi of boost; around 850 whp.

No one has swapped out the internals yet on the N54 because:
- We still haven't hit the limits of the stock internals (no bent rods or failed pistons)
- The compression ratio has not been maxxed out on any of the current setups (including Dzenno's 550 WHP RB Turbo setups or Shiv's 600 WHP Single Turbo)
I expect this to change when the Vargas Stage 3 Turbos & ProEFI are both released. Once people start seeing 700-800 WHP & are using a standalone, we're gonna start seeing the OEM internals fail (~3 times the OEM WHP)
