The Z32 factory wastegate actuators start opening at 7psi, allowing boost to drop off. These units replace the OEM actuators, and will allow you to hold higher boost pressures from spool up to red line. You will be able to hold boost past 6000 RPM with little drop off. These actuators include an adjustable turnbuckle with opposing threads so that the preload can be tighetned or loosened in the car without ever detaching the rod end from the turbo. Other benefits include reducing the amount of boost spike, as well as eliminating the oscillation that is common with light spring wastegate actuators.
This kit includes a custom made bracket to mount up to the factory points on the back of the compressor housing and start opening at 10 psi but are fully adjustable for preload. We recommend running a boost controller with this unit and upgrading your fuel system. Z1 Motorsports Upgraded Wastegate Actuators work with all OEM heat shields.
- OEM Z32 Turbo
- GT 500
- GT 525
Note: These actuators do not come pre set. It is recommended that you install the actuators and set both of them to open at the desired pressure simultaneously. Otherwise, you can set the length to match your OEM actuators to maintain the stock boost pressure.
