Note: NSR camshafts run at the limit of the OEM springs and you MUST ensure that your valves springs are making their rated spec and are not worn/fatigued. Using this camshaft with weak OEM valve springs may result in broken springs and/or engine damage.
NOTE: HP gains are representative of what was achieved by TSP on their in-house dyno and are highly variable depending on your combination's existing modifications and tuning - results may vary.Â
