The stock B16A cams make peak power at 7600rpm and the ITR cams make peak power at 7900rpm. My stock redline is 8000rpm and my stock rev limit is 8500rpm. Is my stock valvetrain capableof safely supporting the ITR cams. I always shift at 8000rpm anyway. Even thoughit would rev within the stock parameters, would the differing lift/duration of the ITR camsstressmy 13 year old valvetrain too much?Or should i buy Skunk2 VS/Rwith these cams?

PS: Down the lineI plan on using B16B pistons (i know the work this entails), would this make a difference todetermining theneed for an upratedvalvetrain?

 

i would say yes because u are using a slighty bigger cam and that 13 year old parts yeah time to get new ones they may bust then again they may not. Its completely up to you bro.
