This Machine Team Modified is better then a stock OS Speed V-spec Worlds II edition, this engine is now like a specially modified OS Speed with a light weight blue head. More top and bottom end and better fuel mileage then a stock OS Speed II engine. This is a fully modified engine, not just 2 cuts with a dremel like some engine modifiers charge $100 to perform. Although this engine will over all out perform any other engine, it is not recommended for non experienced engine tuners as modified engines are more difficult to find the proper tune.
