The only reason why I stated that was because my previous, previous car ('05 RSX Type-S) had the same valves, valve springs and valve spring retainers as the Japanese Integra Type-R.
Our USA RSX-S revlimited at 8300RPM. Their Japanese Type-R revlimited at 8600RPM.
The reflashes available for that vehicle suggest 8600RPM is an absolutely safe RPM based upon the information above. I ran at 8600RPM for well over a year and never had any problems.
I would never suggest revving past the factory revlimiter, but that's not a concern with DSG users, only manual drivers who can actually cause a mechanical overrev due to a poorly placed shift.
