The VS Racing 2101B Competition Off-Road Buggy Engine is a super long stroke .21 off-road engine is based on the powerful O.S. Speed 21XZ-B Spec II. By combining the experience, precision and technology of world famous OS Max engines, with additional tweaks and changes from the mind of legendary Rody Roem, the 2101B delivers a balance between high performance, reliability and cost.

The biggest changes can be found in the crankshaft and the combustion chamber. The 14mm turbo crankshaft and turbo head button have been "Rody Modified". This includes balancing, porting, lightening and silicone ramping the crankshaft intake. The VS Racing 2101B is best suited for high competition 1/8 scale off-road racing and is recommended for "EXPERIENCED" users.

VS Racing 2101B Competition Off-Road Buggy Engine
This Engine is the best engine I have ran in a decade, you can tune and run the engine with a variety of pipes for more bottom, mid to high, mileage, or just raw crazy power. Rody Roem is an amazing person who can be reached if you have questions and the staff at A Main can too. This Engine is a Speed XZB Spec II with similar tuning, Steel Swiss bearings that are higher quality than the OS stock bearings, and the VS Racing crank is specially tuned via Rody that makes this engine so special. Every other Speed II copy is 99% the same almost, the VS is an improvement over the Speed II. I own 4 of these engines, this sale price plus the coupon offer I couldn't pass it up. You can run the 2090 Pipe for all out power ok-decent run time, I would recommend the 2035, smooths out the massive amount of power made by the engine and you gain mileage, I can pit 8-9min w/o problems. Other pipes that work 2050, 2060, 2146, Nova 9886.
