Now you can fine tune your turbo actuator to the exact needs of your engine with this complete tuning kit.
In your actuator tuning kit, you will find four or five springs (dependent on your actuator) and the associated spring retainer. The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest.
Please select from the options above if you require this kit for an 048 or 049 actuator. The 048 actuators are those with a big body, the 049 actuators are those with a standard size body.
Piston 049 acuators and diaphragm 049 actuators use the same springs.
The spring colour codes and their running pressures are as listed below.
T2 049 (Small) Actuator Springs (Both Piston and Diaphragm Type 049):
Green – 10 psi (0.7 bar)
Purple - 13 psi (0.9 bar)
Yellow – 15 psi (1.0 bar)
Blue – 18 psi (1.2 bar)
Red – 20 psi (1.4 bar)
T3 048 (Big) Actuator Springs:
Green - 10 psi (0.7 bar)
Yellow - 12.5 psi (0.9 bar)
Blue - 17 psi (1.2 bar)
Red - 18 psi (1.3 bar)
We normally supply our actuators, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the actuator characteristics to suit a given application.
Note: Serious or fatal damage may occur to the engine and associated components if this product is incorrectly matched to the individual engine requirements. Forge Motorsport nor any of it’s Authorised Distributors can assume any responsibility for any adverse effects resulting from the installation of this product
These kits are NOT suitable for our Diesel actuator for Garrett VNT turbos.

Forge Motorsport is the only outfit to stock just what I needed to complete the world's first intercooled upsercharged A-Series engine project. Good price, high quality springs with flat-ground ends, wide range of tension for fine-tuning the valve actuation--A+.
Customer Service was outstanding. They quickly answered my questions confirmed I was ordering the correct spring kit. They came quickly as I had paid extra for shipping. I needed them while we were making some changes on my car. They were in perfect condition and the blue spring is working exactly how we predicted. Wish we had more vendors like Forge.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
