> Oh, I was under the impression that even k20s with cams/head work were considered reliable to 8.5k, I’m guessing you can’t rev it to 9k+ all that much without sacrificing some longevity :rofl

Everytime I raced all motor I would rev to 8,8…cams will make it more reliable up in that area from what I’ve seen and can extend the revving point a bit.
