Forge Motorsport Waste-gate actuator for the ABARTH, Fiat 500T, Fiat 500L, Fiat 124 Spider, and DODGE DART 1.4L fits directly to the turbocharger casting. Requiring no additional brackets. This wastegate is a great upgrade over the stock wastegate and is highly recommended for those running a tune or turbo upgrades. Designed for adjustability, this is a plug-and-play part on the stock turbo and our 1446+ turbo upgrade. The ability to select a higher tension spring and manually set crack pressure allows for better peak boost precision and sustainability throughout the powerband, especially when combining with tuning.  This product is built with a predetermined actuator spring suitable for at, or slightly above factory boost levels. The actuator can be assembled with a stiffer spring upon request. It is designed and built with the intention of increasing the boost output of a turbocharged system. We cannot guarantee compatibility with all applications, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine management system of the given vehicle at the time of installation, whether that system is factory or aftermarket. This unit comes with the yellow spring pre-installed. For further adjustments and tuning capabilities, we recommend getting the FORGE ACTUATOR SPRING KIT (comes automatically included with the 124 ABARTH/SPIDER)   APPLICATIONS:  FIAT 500 ABARTH FIAT 500T FIAT 500 SPORT (2019+) FIAT 124 SPIDER FIAT 124 ABARTH FIAT 500L DODGE DART 1.4L JEEP RENEGADE 1.4L FIAT 500X 1.4L RECOMMENDED SPRING AND CRACK PRESSURE SETTINGS: Stock Tune (Green Spring/7-10psi CP) Tuned (124 ABARTH/SPIDER Stock Turbo) (Purple Spring/11psi CP) Tuned (All Other Models) (Yellow Spring/13psi CP) Tuned Upgraded Turbo vehicles (Yellow Spring/13psi CP).

While Forge Motorsport is happy to supply you with an actuator capable of holding boost beyond that of your factory unit we are in no way capable of knowing nor suggesting that your vehicle's engine or related systems are capable of supporting or surviving the stresses of such elevated boost pressure.
