The Bullet RB26 Billet Block to suit Nissan RB26 applications has been proven in World Time Attack competition.

This product has vastly improved block rigidity and improved deck thickness over the stock unit. Combined with increased head stud diameter this product delivers exceptional head sealing qualities. Distortion of cylinder bores and crank tunnel is dramatically reduced through design improvements and a Bullet 4 bolt main cap system.

This product offers significant weight savings and has minimal modifications to directly replace the standard block.
