With these engines there is absolutely no issue with running them to the OEM rev limiter on a regular basis. They are built for it and more than happy to do it. My last one (an 01 AP1) I had from 66k to 175k miles with tons of AutoX and track days without so much as a hiccup from the engine itself. Lots of time spent at or near 9000rpm, riding the 2nd gear rev limiter through slaloms at higher speed autox events, shifting at the rev limit almost every shift on track etc... that car went backwards into a wall on track last year and now belongs to a friend who is rebuilding it for track-only use (JustinGadell on instagram and other socials)

my '15 Subaru WRX on the other hand, I try not to rev all the way to its 6700RPM redline habitually and instead shift between 6000 and 6500. But that car runs out of breath above 6k anyway.
