Nissan SR20DET Billet Cylinder Block by Bullet Racing.
The Bullet SR20 to suit Nissan SR20 applications has been proven in World Time Attack applications including 2016 winner The MCA Hammerhead. In dry-deck drag racing applications it has been proven at outputs exceeding 1800hp
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. The standard cast alloy unit suffers from high distortion which is eliminated with the Bullet product.
