21VZ-B V-Spec-T

AU$379

The raw power to exploit a split-second opportunity is there, tempered by the ability to fine-tune and finesse throttle control to the needs of different tracks and situations. And to help keep the 21VZ-B V-Spec-T (P) at the peak of its power, O.S. has given it a billet aluminum piston, hardened ABC sleeve for added wear resistance and a new crankshaft design that's simultaneously slimmer and stronger than any O.S. crankshaft ever made. The 21VZ-B V-Spec-T (P) ? designed for first-place finishes over the long haul ? from O.S.

More power and durability. The brass sleeve is chrome-plated for performance and hardened to withstand the wear that racing action can produce. CAD-refined and CNC-machined ports smooth airflow and boost power.

Track-tune in seconds! Increase control on low-traction tracks by inserting the 8 mm (red) or 9 mm (blue) carb restrictor. Takes only a second, but pays off, lap after lap.

.28XZ Truggy Engine

AU$439

 With input from top truggy drivers, O.S. has developed the ideal engine for these hybrid hot rods! The 28XZ produces more low-end torque, providing the rpm/torque balance that heavier truggies require. The result is power that's incredibly smooth, for truggies more drivable than ever thought possible!

The larger head aids in cooling, and is a 2-piece construction with inner head button.

A sealed front bearing and high-performance inner bearing are part of the new crankcase design.

The high-performance con rod features oiled bushings.

Three needles enhance fine-tuning on the 21J slide-valve carb.

Comes with a high-performance P3 hot turbo plug.

The Mark Pavidas Edition Tuned Pipe (OSMG2969) is the perfect accessory for the 28TZ; flywheel sets are required (OSMG2648 for Mugen, OSMG2649 for Kyosho, both sold separately) for certain truggy models.
