This is the S-POWER S3 Off-Road Competition Buggy Engine. The S3 delivers top-of-the-line, affordable, competition-caliber performance and is much more affordable than you might expect. If you like the power of the O.S 21VZ-B V-Spec, the S3 provides users with improved torque and acceleration. The S3 features an improved three needle carburetor with a 7mm venturi for fine tuned control, while retaining the easy to tune characteristics that OS engines are known for. The S3 also features a stronger crankcase and weighs less than the previous VZ-B, for improved durability and a lower center of gravity.
