oThe O.S. Speed B2103 Type S 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. This S Type has high vertical finned, low-profile cooling head with low gravity for improving the cars handling. The crankshaft has been updated to optimize the rotational mass and follows the O.S. SPEED tradition with 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, and a three port sleeve that will perform well at medium and low speed ranges.

This engine also features the 22D carburetor which emphasizes quick response and smooth acceleration. This combo includes a T-2100 SC tuned silencer with M 2004 (85 mm) exhaust manifold, 6mm and a 6.5mm venturis, and a re-designed ball link which allows a change in the position of fixing screw for easier access
