The Quick Time RM-4089 bellhousing connects E36 BMW M52 Engines (inline six) to Chevy T56 or Chevy Magnum T56 Transmissions. This bellhousing 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. This bellhousing is a universal fit bellhousing and is not vehicle specific. The Quick Time bellhousings are produced using a unique spin forming process which results in a very high strength material. This high material strength allows the Quick Time bellhousings to be light weight while maintaining the protection you desire.
