Bullet Race Engineering Nissan SR20 Block Only

PLEASE NOTE: We will NOT be proceeding with machining the block for Fire Rings unless you contact us when placing the order. Deck heights, compression ratios, piston to head clearances all need to be confirmed. If you don't contact us, we will supply the fire rings only.

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.
