About the X5G V2 On-Road Nitro Engine

Enhanced 5-Port Power Delivery

The updated 5-port configuration features optimized sizing and port timing to improve airflow and fuel delivery. This results in strong, usable power with excellent throttle response, making it ideal for GT racing conditions. The revised sleeve design further enhances efficiency and output, allowing drivers to push harder with confidence. Smooth and predictable power delivery ensures better control through corners and acceleration zones.

Efficient & Durable Internal Design

The Evo high-pressure injected crankcase works in combination with a balanced DLC-coated crankshaft to improve durability and internal efficiency. Rear ceramic bearings reduce friction, increasing longevity and maintaining consistent performance over extended runs. Optimized cylinder machining helps reduce fuel consumption without sacrificing power. These features combine to deliver a reliable engine platform suited for long race sessions.

Precision Tuning & Race Control

Equipped with a triple-adjustment carburetor, the X5G V2 allows for fine-tuned performance across varying track conditions. The low-profile venturi enhances airflow for improved throttle feel and fuel efficiency. A turbo backplate and updated carb ring contribute to smoother operation and consistent tuning characteristics. Together, these features provide racers with the control needed to maximize performance on race day.
