    M20 2.7L Cam Upgrade

    Hey guys. I'm new to r3 and this is my first post. I'm building a 325es track car right now and I'm using the "e" bottom end and the "I" top end. Before I put the cylinder head on I was wondering what the biggest duration cam I can run and how high I can rev to without shit hitting the fan on my new motor. The bottom end is all stock and I have everything else for the swap, just wondering if I could throw a cam in it because I love the sound of a cammed m20.
    Thanks

    Do a mock up and check piston to valve clearance with a stock b25 cam from that you'll at least know some of the physical limits as there isn't much info on bigger cam with eta shallow valve reliefs. The valve springs and rockers (brand )also come into to the rpm. In general 7k is a ballpark number that you don't want to exceed without using specific parts with that in mind
