Forge Motorsport Alloy Adjustable Turbo Actuator for Lotus Esprit
The Forge Motorsport Alloy Adjustable Turbo Actuator is specifically designed for the Lotus Esprit with 2200cc 4-cylinder engines. This high-quality actuator is made from 6026 grade aluminium and is manufactured in the UK. It is supplied without a replacement bracket, so you will need to reuse your original factory bracket to fit the Forge actuator.
Forge Motorsport is a leading company in the design and manufacture of billet two-piece replacement aluminium turbo actuators. They were one of the first companies to develop these actuators for various turbocharged vehicles, including the Cosworth, Renault 5 GT turbo, and Lancia Integral turbos. With their extensive experience, Forge Motorsport offers a wide range of actuator replacements.
The Forge Motorsport Alloy Adjustable Turbo Actuator offers several features and benefits:
- Choice of spring pressures to suit your car
- Vehicle and turbo specific
- Built to order and machined in the UK
- Choice of piston or diaphragm operation on most actuators
- Nomex reinforced flurosilicone diaphragms
- Laser cut stainless steel brackets (where applicable)
- Tuning and service kits available
- Made in England with a lifetime warranty*
When you install a Forge turbo actuator, you can fine-tune and manage your specific boost requirements, resulting in improved response and better control. The actuator comes with a predetermined spring suitable for factory boost levels, but it can be assembled with a stronger spring upon request for tuned vehicles or higher boost levels. Please note that compatibility with all applications and the ability to increase boost output beyond the engine-management-system parameters cannot be guaranteed.
The Forge Motorsport Alloy Adjustable Turbo Actuator is available with diaphragm sealed internals as the default option. However, customers now have the choice of piston sealed internals, which offer equal performance and low maintenance.
