The 4P TR3 racing camshaft was specifically designed for our 2.0L K20C1 race engine program. The primary lobes allow for a stock idle and tame drivability perfectly suitable for everyday use in traffic, but with significant power gains over stock.  You will experience a much more audible and traditional VTEC crossover that was lost in the OEM K20C1 and much more RPM capability over an OEM camshaft. 

Gains of 40-60+hp are realized through the RPM range, and more as you continue to pull beyond 8000 rpm.   Camshafts are supplied with cam card and VTC limiting pins with detailed photo for their placement.
