*** AS PROVEN ON MICKS MOTORSPORTS SR20 200Sx - 6.84@206mph - Factory Block - Plazmaman Girdle and Main caps ***

Raise the limit of your SR20's bottom end reliability with a Plazmaman billet main girdle.

Unlike the factory unit, the Plazmaman's billet girdle solidifies the lower components of the engine by tying the main caps to the intermediate sump. This prevents twisting and warping of the block under high horsepower

Essential to eliminate main cap walk for applications over 600rwhp / 450rwkW

  • Comes pre-drilled to suit 1/2" ARP main studs.
  • OEM diameter bolts can also be used.
  • All bolts to fit onto engine are supplied with kit.

*** Now available to work in conjunction with billet Girdle - Plazmaman Billet 4140 Main caps - see Engine section of website***
