and 11L Rotary Carburetor.

FEATURES

Oversize case fins dissipate heat to keep engine temperatures lower
Five port cylinder liner for increased air flow
12mm rear bearing lessens vibration and allows engine to handle more
torque
Rotary carb
Small diameter recoil design for easier manifold installation
Super-hot turbo P3 glow plug for more power and improved fuel economy
Rear exhaust with a round port
Two-piece head design (inner head or head button and outer head)

INCLUDES

One 18TZ turbo engine with threaded shaft, 11L rotary carburetor,

REQUIREMENTS

Muffler (exhaust system) depending on vehicle
Starting equipment
Fuel: 5% - 20% nitromethane content
Most of the fuels we carry meet or exceed the lubricant content
required for maximum engine performance and long life. In the past
conventional lubricant content used in fuel was 18%. But with new
advanced technologies, fuels like Red Alert and O'Donnell have a
better quality of lubricants even thought the percentages of
lubricant content are lower. These high tech lubricants provide
exceptional cooling and protection.
