Just curious what valve train upgraded you guys are running. I have a fully built b16 and my car definitely shows on the dyno it wants make more power past 8000 rpms. What do I need to safely rev to say 9000? i was thinking of using type r cams with my setup but am undecided. thanks!

 

skunk 2 or crower is good, you're gonna need better cams if you wanna make power to 9k
