FAQs
Do I need upgraded valve springs?
Yes, a Stage 2 profile typically requires stiffer springs to control valve motion at higher rpm. See our 12V valve spring options.
Will this cam work with my stock turbo?
It can, but the greatest gains are realized with larger single or compound setups. Explore turbo kits for 12V.
Is tuning required?
Mechanical 12V engines benefit from fueling/timing adjustments to maximize this cam. Consult our timing tools & resources.
Do I need to degree the cam?
Degreeing is recommended for precise setup. Verify piston-to-valve clearance and retainer-to-seal clearance on your build.
What else should I replace while I’m in there?
Consider new tappets, front cover gasket set, and a timing/cam gear.
