Now Honda owners can discover the Dart advantage!
We applied our decades of racing experience to design and manufacture the first heavy-duty block for Hondas. Working in conjunction with leading industry professionals, we engineered the new Dart aluminum Honda block to solve the shortcomings of production blocks used in high-performance and competition applications.
We offer the Dart block in two versions that replace B18 and B20 castings. Both are built to withstand the extreme cylinder pressures created by turbochargers
and nitrous oxide injection. We increased wall thicknesses in all critical areas and beefed up the bottom end with steel main bearing caps. Best of all,Dart blocks are compatible with production Honda cylinder heads, internal components and accessories.
We produce Dart blocks for Hondas on all-new tooling and machine them on state-of-the-art CNC equipment.
We added the features that sport compact racers and performance enthusiasts need to build powerful and reliable engines. Take a close look and you’ll see why Hondas dominate with Dart!
*Dart B18 block has stock deck height and choice of standard 81.5mm bore or optional 84.5mm bore
*Dart B20+ block has extra-tall 8.900 (226mm) deck height and 84.5mm bore for increased displacement
*Aerospace quality C355-T6 virgin aluminum alloy provides maximum strength and durability
*Replaceable ductile iron dry sleeves are fully supported to reduce bore distortion and enhance ring seal
*Closed deck design increases rigidity and improves head gasket sealing
*Steel main caps with high-strength bolts increase bottom end strength and minimize bearing bore distortion
*Strengthened main webbing increases rigidity and improves head gasket and sleeve life
*Extra large water jackets enhance coolant circulation around cylinder barrels
*Machined for piston oil sprayers (not included) to reduce piston temperatures and prevent detonation
*Uses stock components, including oil pan, oil pump, water pump, alternator, and timing belt tensioner
*Precision CNC machining ensures consistent high quality and eliminates expensive “blueprinting.”
