The Bullet RB30 to suit Nissan RB bolt-up applications has an increased block height compared to RB26. It has been designed to suit applications producing 2500hp.
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 delivers scope to create large displacement RB engines.
The optional Bullet Fire Ring head sealing system uses a metallic gasket with grooved brass rings for the cylinders that provide exceptional head sealing under ultra high loads.
Increased deck thickness increases rigidity and stability for better head gasket sealing.
Bullet supply premium studs and block plugs with all billet blocks.
Our blocks are machined from 6061 aircraft-grade billet aluminium, so they are much lighter than cast iron alternatives. Typical weight savings are more than 20kg.
Our unique design incorporates siamese bores, dry sleeves and a one-piece cradle resulting in maximum rigidity. Cylinders stay round and piston rings seal better under high load resulting in more power.
Four bolt, billet one piece main cradle improves bottom and rigidity to reduce main tunnel deflection under extreme load. The cradle is made from the same material to ensure equal expansion rates and maintain a round bearing housing at different temperatures.
Bullet’s registered designs are developed to identify and eliminte structural weaknesses in OEM blocks. They are built to exceptionally precise tolerances for exceptional results.
Cooling system design improvements and efficient fluid paths are a significant feature of the Bullet block.
