For today’s competition driver, turbo is the way to go...and no other turbo engine goes like the 18TZ from O.S. It outperforms all other .18-size engines, delivering race-winning “outlaw” power for 1/10 scale buggies, stadium trucks and touring cars.
- Oversize fins on the case dissipate heat to help keep engine temperatures lower.
- Five ports in the liner increase air flow for more power.
- The rear bearing is 12mm in diameter, which lessens vibration and allows the engine to handle more torque.
- A super-hot turbo P3 plug is included for better burn, more power and improved fuel economy.
- The 18TZ-TX version features a new compact recoil starter that’s smaller and lighter, making it easier to install.
