For this motor I was given one task, make the meanest 13b I could. This motor got a half-bridgeport, resurfaced housings, and a RacingBeat front pulley. We also sent the rotating assembly to Mazdatrix for lightening, race clearancing, and balancing. The rotor housings and front cover were paint matched to the body color of the '72 Datsun 1200 that this engine would be powering. A maxed-out 13b in a car that weighs under 1400lbs.
