The Tomei Poncam Camshaft Set (part number TA301B-NS06B) is a matched intake and exhaust pair designed specifically for late-production R33 RB25DE(T) engines equipped with NVCS, covering vehicles manufactured from approximately September 1997 to September 1998.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis Poncam specification features a 256° duration and 8.50 mm lift on both intake and exhaust sides. As part of Tomei’s milder Poncam range, these shafts are intended to improve airflow and throttle response while remaining suitable for street-driven and mildly modified engines. The profile works with the NVCS system on late R33 RB25 engines and provides a practical step up from stock cams without the more aggressive characteristics of higher-lift Procam options.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThese 256-8.50 Poncam shafts are a well-matched upgrade for late R33 GTS25T or similar RB25DE(T) builds seeking better response and usable power gains. Proper installation and professional tuning are recommended to realize the benefits and maintain reliability. At Terra Firma Automotive, we supply this genuine Tomei Poncam Camshaft Set as a capable performance option for late R33 RB25 owners.
