Honda DART Blocks
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!
“The new Dart B-series block cures all of the problems associated
with prepping a factory Honda block for serious horsepower”

Honda Block Features: |
- 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.”
