O.S Speed B2103 Type-R & Type-S engines

O.S. Engines have introduced their new Speed B2103 Type-R and Type-S 3.5cc buggy engines. As for the Type-R engine, the long-stroke 5-plus-3-port power plant was developed for medium to high speed tracks and it features a new crankcase, end cap and 22E carburettor with the DLC-coated crankshaft coming tungsten balanced. The engine utilises a tall cooling head for best possible cooling in high ambient temperatures.

As for the Type-S engine, the 3—plus-1-port long-stroke power plant offers increased torque in the low to mid RPM range while being easy on fuel consumption. The engine utilises the same updated crankcase, end cap and DLC-coated crankshaft, but comes with a more efficient 22D carburettor for smoother throttle response and greater mileage. The engine sports a low-profile cooling head for an overall lower centre of gravity. Both engines come with a rear ceramic bearing and they are available as engine only or including the T-2100SC exhaust and 85mm M2004SC manifold set.
