I want to know what are the benefits for me going with the SPR Cams oppose to the NSR Cams. My heads are stock. Will I be able to raise my rev limiter to say 6800rpms with the springs required.
The SPR's make more power than the NSRs do, plus you can definately raise your rev limit safely with the upgraded valvetrain. I shift at 6800-7k, been doing it for over a year with no issues.
