This is New JP GIMAR TEAM .21 On/Road 7 Port Turbo Race Engine.

Crankshaft
This is a special balanced crankshaft. Made to meet even the highest standards of our most demanding drivers. Slightly reduced rotational mass and greatly improved fuel flow provide great performance.

Sleeve:
This Piston/Sleeve set is optimized for use in EFRA/IFMAR competition events and is made from hard chromed brass and features 7 transfer ports.

Combustion chamber:
The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.

Conrod:
The conrod is made from superlight&superstrong alluminium to make the lightest and strongest possible conrod to withstand the abuse of a .21 racing engine.

Rear Ball Bearing:
The rear ball bearing has high quality steel balls to minimize wear and inertia to improve acceleration and fuel consumption.
