Turbosmart 08+ Nissan R35 GT-R 7 PSI Internal Wastegate Kit

If you're looking to get more out of your R35 GT-R's factory turbochargers, this internal wastegate kit from Turbosmart is a solid option. It's designed to replace the stock wastegate actuators, giving you better control over boost pressure and improving how quickly the turbos respond when you get on the throttle. This means you can expect a more immediate surge of power and a more consistent boost level throughout the RPM range.

Turbosmart built these actuators with a higher 'Working Ratio' than the factory units. What that means in practice is they can react more quickly to changes in exhaust pressure, helping to prevent overboosting and keeping your boost levels right where you want them. The main body is made from high-grade billet aluminum, which is strong and lightweight. Inside, you'll find a proprietary silicon Nomex diaphragm that can handle the heat and pressure, along with stainless steel rods and clevis for durability. The kit also features Turbosmart's unique locking collar system, which makes it easy to adjust and secure the wastegate spring tension.

This particular kit comes with a 7 PSI spring installed, but Turbosmart offers optional springs ranging from 3 PSI up to 26 PSI, so you can fine-tune the boost to your specific setup. Keep in mind that this kit is not CARB approved and cannot be shipped to California. For installation, you'll be replacing the stock actuators, which is a common upgrade when working on the GT-R's twin-turbo setup.
