Forge Motorsport Turbo Actuator for Vauxhall Astra SRi/GSi/VXR with Z20 Engine and K04 Turbo
The Forge Motorsport Turbo Actuator is specifically designed for the Vauxhall Astra SRi/GSi/VXR with the Z20 engine and K04 turbo. This billet two-piece replacement aluminium turbo actuator is manufactured from high-quality 6026 grade aluminium, ensuring durability and performance.
With a choice of spring pressures, you can customize the actuator to suit your car’s specific needs. Whether you’re looking for improved response or better control, the Forge Motorsport Turbo Actuator allows you to fine-tune and manage your boost requirements.
Featuring vehicle-specific and turbo-specific designs, this actuator is built to order and machined and hand polished in the UK. It comes with a choice of piston or diaphragm operation, with nomex reinforced flurosilicone diaphragms for added strength and reliability.
The Forge Motorsport Turbo Actuator also includes laser-cut stainless steel brackets (where applicable) and is backed by a lifetime warranty*. Tuning and service kits are available for further customization and maintenance.
When you install the Forge Motorsport Turbo Actuator, you can expect improved boost output and performance. However, it’s important to note that compatibility and boost levels are subject to the engine-management-system of your vehicle. Forge Motorsport cannot guarantee compatibility with all applications or the ability to increase boost beyond the parameters set by your vehicle’s engine-management-system.
This actuator is available with diaphragm sealed internals as the default option, but customers now have the choice of piston sealed internals. This innovative design offers equal performance to the diaphragm type and requires less maintenance.
Included in the box is one FMACAVXR actuator and one Forge sticker. If you require the FMPACTUN spring tuning kit, it can be purchased separately.
