A very rough comparison, for modern/aluminum case 5 spds, is strength vs weight. The R154/turbo Supra 5 spd.weighs 100 lbs. w/o bh. T5 = 75lbs and Tremec 5 spd. listed at 113 lbs.(does'nt mention bh. My R154 is going against a na. 6.1L on E85. We shall see. The 183" T Supra motor will hold about 5.5hp. per in.,(sturdy).ateam:dontknow:
