why are the gsrs and new integras able to rev so high? the gsr stock red lineis 8k … … and the type r can rev to 9k?.. something like that… and the newer ls’ can rev to 7 or something. why? … thanks, matt
It is mainly a difference in internals. They have different rods, pistons, cranks, same bore but different(shorter) stroke, valve springs, etc… These internals are designed to allow and withstand high revving.
