The latest batch of CISON V8 engine kits arrived at the Stirlingkit warehouse in August 2025, and stock is limited — so we recommend ordering as soon as possible. These kits are produced in limited batches, and while the number of key components (like crankshafts) is fixed, not all parts pass quality inspection. If your order falls into the affected range, it will be fulfilled in the next production round, which typically takes 60–90 days. Before shipping, Stirlingkit also performs a second full inspection — if any issues or missing parts are found, we send the product back for correction. If the kit is in stock, your order will usually ship within 24 hours. For the latest updates, please check our product page or blog, or email us at service@stirlingkit.com to check your shipping status.

While it's inspired by classic V8 engines, the front-mounted distributor differs from the original design. This adjustment ensures easier access and smoother operation within the compact model structure. Some enthusiasts may notice this distinction, but it does not affect the model's performance or assembly experience. Additionally, this model prioritizes assembly ease and compatibility for various applications, such as modifications or integrations with RC cars.
