This automatic transmission torque converter is designed to significantly lower ET's and help launch higher boosting cars using the factory automatic transmission.

Please choose the torque converter stall speed that best suits your application or email us direct for assistance.

3200, 3800, 4400 rpm stalls available. Stock twin Supras running elevated boost would benefit most from a 3200 rpm converter. Those running slicks at elevated boost on the stock twins and possibly nitrous would most benefit from 3800rpm stall. Larger turbo cars or those running 21psi and nitrous on the stock twins with slicks could benefit from the 4400rpm converter.
