This is the Novarossi ISON .21GT TUNED 5 Port .21 Long Stroke Rally Engine. This engine features a silicone ramped and tungsten slugged "Tuned" crankshaft for incredible acceleration.
- Conrod: The R7 conrod is made from a super light aluminum which has been checked ultrasonic. The specific form of the R7 creates little turbulence inside the engine while running.
- Sleeve: The sleeve has 5 transfer ports and is made from hard chromed brass (true ABC construction.
- Crankshaft: The crankshaft has been ground to increase the mixture flow and has a special shape to reduce turbulence inside the crankcase. The balancing is done by 2 inserts made of tungsten alloy and the inlet has a silicone filling to reduce the weight of the crankshaft for improved acceleration.
- Glowplug: The glowplug of the engine is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and therefore are not interchangeable with engines that use Standard glowplugs.
