These Quick Time bellhousings mate a GM style T-56 Magnum or T-56 Viper Transmission to the popular S2000 (p/n RM-4011) Honda engine and (p/n RM-4012) K20/K24 L4 engine. Built from high-quality grade steel, the cone is spun not stamped or rolled making this bellhousing dimensionally stable and accurate. It is S.F.I. 6.1 certified, which is required by many sanctioning bodies for cars running 11.49 or faster in the quarter-mile and is not vehicle specific. The unique spin-forming process allows the bellhousing to be lightweight while maintaining the protection your customer desires.
