The Bullet SR20 was the first of our Billet engines to be used at the World Time attack Challenge. Along with the Genius of Murray Coote at MCA suspension the reliability of the billet SR20 helped MCA take out the number 1 spot in 2016 & 2017. MCA's achievements showed the benefits of using a Bullet Billet Block and changed to game for time attack competitors across the globe.
This product has vastly improved block rigidity and improved deck thickness over the stock unit. Distortion of cylinder bores and crank tunnel is dramatically reduced through increased material thickness and a Bullet 4 bolt main cap system. This product requires minimal modifications to directly replace the standard block.
