The Bullet 4G63 DSM 7 Bolt product is a bolt up replacement for 2nd Generation Eclipse and Talon applications as well as Mitsubishi EVO 1-3.
It has been engineered to deliver reliability in 1700hp environments.
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 offers significant weight savings and has minimal modifications to directly replace the standard block.
The Bullet 4G63/64 comes in 3 models, Wet or Dry Deck (open or closed deck) with water jackets & a Solid Drag only version.
