Product Description

The Turbosmart TS-0610-2072 IWG75 Internal Wastegate Actuator is a high-performance replacement designed specifically for the 2003 Mazda Protege equipped with its factory turbocharger. With a pre-installed 7 PSI base boost pressure spring, the actuator enhances turbo response and delivers a broader, more stable boost curve compared to many stock units. Thanks to Turbosmart's increased diaphragm surface area and improved working ratio design, this actuator helps achieve peak boost earlier and maintain boost pressure more consistently throughout the RPM range. 

Built with a billet aluminum housing, a reinforced Silicon Nomex diaphragm, and stainless steel actuator components, the TS-0610-2072 offers durable performance under high-temperature and high-pressure conditions. The locking collar system allows secure preload adjustment and quick spring changes when tuning for elevated boost levels. Typical installations require only standard tools and the included mounting hardware, making this a direct bolt-on upgrade for enthusiasts seeking better boost control without major modifications.

While the base 7 PSI configuration maintains modest boost pressure similar to stock, those looking for more aggressive settings can upgrade springs (sold separately) and tune the engine management system accordingly. This makes the TS-0610-2072 ideal for street and light performance builds on the Mazda Protege turbo platform.
