{"product_id":"tr3-2-0l-k20c1-racing-camshaft","title":"TR3 2.0L K20C1 Racing Camshaft","description":"The 4P TR3 racing camshaft is engineered for the 2.0L K20C1 race engine program, specifically for the FK8 and FL5 Civic Type R models. However, it also delivers significant power gains over stock and a much more audible, traditional VTEC crossover that is often lost in the OEM K20C1. The TR3 camshaft offers increased RPM capability compared to OEM units and is constructed from a billet core for maximum durability.\n\nPerformance specifications include an Intake Lift of 0.491\" and an Intake Duration of 234 @ 0.050\", with an Exhaust Lift of 0.494\" and an Exhaust Duration of 238 @ 0.050\". Gains of 40-60+hp are expected throughout the RPM range, with potential for more as you pull beyond 8000 rpm. The camshafts come supplied with a cam card and VTC limiting pins.\n\n**Important installation notes:** Aftermarket valve springs are required, as the TR3 camshaft will coil bind a stock valve spring. Recommended options include the 4P Spring KIT TRKTR3 or Ferrea KT4033 with an SL1153 spring seat on the exhaust cam. Failure to use the SL1153 spring seat with the Ferrea KT4033 can lead to coil binding. The Ferrea KT4038 can be used but will eliminate VTEC functionality. The recommended rocker arm is the OEM Honda Rocker Arm.","brand":"4P","offers":[{"title":"Default Title","offer_id":52686706999608,"sku":"4P-TR3","price":1200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178034.webp?v=1784876074","url":"https:\/\/store.motormia.co\/products\/tr3-2-0l-k20c1-racing-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
