Replacing the wastegate spring is the easiest cheapest and a very accurate way of raising your boost level. These genuine Turbosmart springs suit their 38mm, 40mm and 45mm gates. Available in 5, 7, or 10psi options (please specify when ordering). To gain other pressures you need to combine multiple inner, outer and middle springs. Need help? Please email us!
