The Honda Civic Si is a popular choice among car enthusiasts, particularly for those looking to enhance performance through turbocharging. When considering turbo kits, one of the key decisions revolves around the size of the wastegate and the brand of the turbocharger. This article will explore the differences between 9mm and 10mm wastegates and the merits of choosing between BorgWarner and Precision turbochargers.
Understanding Wastegate Sizes
Wastegates play a crucial role in managing the boost pressure produced by a turbocharger. The size of the wastegate can significantly affect performance, responsiveness, and reliability. The two common sizes for Civic Si turbo kits are 9mm and 10mm.
