SOLD OUT!!!! We are still taking orders, and are grinding more cams. Stock will be replenished by July 15, 2022
The 4P TR2 drop-in camshaft was specifically designed for easy installation into a stock 2.0L K20C1, on a stock valve spring. These can be easily installed in about 2 hours by an experienced technician....it may take you a touch longer if you are feeling your way through it. 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. These are made from a billet core camshaft to ensure maximum durability.
Gains of 25-40+hp are realized through the RPM range, and more as you continue to pull to 8000 rpm. Camshafts are supplied with cam card and VTC limiting pins with detailed photo for their placement.
Stock valve springs are OK with this cam. It is a true DROP IN.
