O.S. Speed B2103 Type R .21 Competition Nitro Buggy Engine w/T-2100SC Pipe

The O.S. Speed B2103 Type R Buggy Competition Engine with the T-2100SC Pipe gives you the advantages and options expected of a competition grade power plant. O.S. has created a product that will evolve to meet driver preferences and course layout.

This model has a re-designed crankcase, engraved with the “O.S.” Logo featuring an updated cooling fin with enough surface area for effective heat dissipation that gives the buggy engine a powerful look. The crankshaft has been updated to optimize the rotational mass and follows the O.S. SPEED traditions of a DLC coating to reduce friction, dual tungsten slugged counter-balance and a ceramic rear bearing to reduce vibration and increase RPM. The inner head has a silicon O-ring for improved vibration reduction and better dust resistance. This combo features a set of exhaust system parts, including the T-2100 SC tuned silencer and a M 2004 (85 mm) exhaust manifold. This engine also features a re-designed ball link which allows a change in the position of fixing screw for easier access, a 6mm and a 6.5mm venturi, and a five-ports liner which performs excellent at medium and high speed ranges.
