Modular Head Shop - Comp 3V XFI NSR Cams
The Comp Cams XFI NSR Camshafts are designed for a true Drop In installation and do not require upgraded Valve Springs or any Phaser mods. We do suggest a custom tune after installation for the best power gains.
If you need help selecting a camshaft for your application, whether it be N/A, Blower, Nitrous or Turbo, we will be happy to help. Please send us an email at ModHeadShop@gmail.com with as many details on your current setup and your overall goals.
