This is the Novarossi ISON Tuned 7 Ports .21 On Road Engine. Novarossi is dedicated to giving 1/8 on road racers a cost effective power plant, that punches far above its pay grade. The ISON .21 features a 7 port sleeve and a slugged/ramped tuned crank, to provide a reliable engine that produces the power needed to race, at a price that makes it a great practice engine. 

Features:

  • Conrod: The R7 conrod is machined from super light aluminum that has been checked ultrasonically. The unique shape of the R7 rod creates less turbulence inside the engine.
  • Sleeve: The 7 port sleeve 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 achieved using two tungsten slugs, and the intake has a silicon filling to reduce weight and improve acceleration.
  • Glowplug: The glowplug of this engine is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and therefore are not interchangeable with engines that use a standard glowplug.
