Product Details

If you're looking to fine-tune the boost pressure on your Mazda RX-7 FD3S with a 13B-REW engine, this HKS Special Wastegate is a key component. It directly controls how much exhaust gas bypasses the turbocharger, which in turn regulates the maximum boost your engine can produce. Getting this right is crucial for both performance and engine longevity, especially when you've upgraded your turbo setup.

This wastegate from HKS is built with their reputation for precision in mind. It's designed to handle the demanding conditions of a high-performance rotary engine, ensuring consistent and reliable boost control. The internal diaphragm and spring are calibrated to work effectively with the FD3S platform, helping you achieve the specific boost levels you're aiming for without over-boosting. Proper wastegate function prevents excessive pressure from damaging your turbo or engine internals.

When installing this wastegate, pay close attention to the vacuum lines and their routing. Incorrect plumbing can lead to unpredictable boost behavior. It's a solid option for anyone serious about optimizing their rotary engine's forced induction system. Remember, this part is not CARB approved and cannot be shipped to California.
