This actuator is suitable for a number of engine installations in the 850,S60,S70,V70,C70 range. There are two variations of this actuator available, FMACT5S – with a straight connecting rod, and FMACT5B where the rod has an offset or bend. Please see the fitment lists below to determine which version should fit your vehicle:
FMACT5S (Straight Rod) This is compatible with the models below, with the Bosch Motronic 4.3 / 4.4 ECU fitted as standard, as seen in models with an accelerator cable. The original actuator rod is straight and suitable for the Mitsubishi TD04HL straight flanged turbo. • 850 R 1997 - 1998 • 850 T-5 1997 - 1998 • 850 T5-R 1997 - 1998 • S70 T5 1997 – 1998 • V70 T5 1997 – 1998 • C70 T5 1997 - 1998
FMACT5B (Bent Rod) This is compatible with the models seen below with Bosch Motoronic 7 and Motronic 7S ECU fitted as standard, as seen in models without an accelerator cable (drive by wire / ETM). The original actuator rod is stepped and suitable for the Mitsubishi TD04HL angled flanged turbo type. • S70 1999 - 2000 • C70 (phase 1 and 2) 1999 - 2005 • V70 (phase 1 and 2) 1999 – 2004 • S60 (phase 2) 2000 – 2004
If you have a later K24 Turbo models (2004/2005/2006 and 2007) with 6 speed manual or automatic gearbox, please see Forge Motorsport part number FMACS60R.
Please select the actuator rod, straight or bent, and colour of spring in the options above.
Forge Motorsport were one of the first company’s in the world to design and manufacture the billet two-piece replacement aluminium turbo actuator. Originally for the Cosworth, Renault 5 GT turbo, and Lancia Integral turbos, we soon developed the largest and most diverse range of actuator replacements.

When you fit a Forge turbo actuator you will be able to fine tune and manage your specific boost requirements, this will allow for improved response and better control. This product is built with a predetermined actuator spring suitable for, or slightly above factory boost levels. The actuator can be assembled with a stronger spring upon request for tuned vehicles, and where a higher boost level is required. Please contact us directly concerning this process. 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
Diaphragm sealed internals are the default selection for this actuator product but customers now have the option of piston sealed internals. Unique to Forge Motorsport, this innovation offers equal performance to the diaphragm type and low maintenance due to the hard wearing nature of piston sealed valve internals.
Forge Motorsport nor any of its authorised distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of allowing for the desired level of adjustment. 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.

This actuator is built with a stock spring as standard. If you require the FMPACTUN spring tuning kit seen in the associated products below, you will need to select the Diaphragm Type 2, 049 option.
All actuator rods are manufactured from 303 grade stainless steel.
Please note that the quoted spring pressure against the various colour codes relates to the mechanical aspect only, applicable to earlier turbocharged engines that are not ECU/solenoid regulated.
However, modern ECU/solenoid engines do not require the target boost pressure to be matched pound for pound by the quoted mechanical specification of the springs we offer. Please take advice from an appropriately qualified tuner if you are unsure of the correct spring application for your model and the planned level of tuning.
For our T2 spring range (FMAS049):
• Red spool up/opening pressure 17 psi /1.1 bar running pressure/full stroke 20 psi/1.4 bar
• Blue spool up/opening pressure 14 psi/ 0.95 bar running pressure/full stroke 18 psi/1.2 bar
• Yellow spool up/opening pressure 9 psi /0.6 bar running pressure/full stroke 15 psi/1 bar
• Purple spool up/opening pressure 7 psi/0.5 bar running pressure/full stroke 13 psi/0.9 bar
• Green spool up/opening pressure 5 psi/0.35 bar running pressure/full stroke 10 psi/0.7 bar

The Volvo 850 T-5R that this actuator has been fitted to is 22 years old. It still has a good engine after 175k, and as such is a good base for tuning to keep up with modern cars.
If you're going to tune the car, then the OE actuator isn't going to give you much more in the way of performance. Basically, it will let go of your boost pressure at the drop of a hat, as will the cbv (dump valve) in the interests of engine safety.
I've got both these items from `Forge` fitted to my car, and I needn't worry about any loss of boost thanks to that. It's up to you how tough you want to go in regard to internal springs, which are interchangeable etc. Even with the stock (green) spring, it's an improvement on the factory equipment.
When you decide you want these things; then you want them right away. I sent off for, and received mine in two days. Had them fitted that afternoon (not difficult) and tested. So, pleased, handy to be able to get stuff like this these days for a 22yr old car.
The majority of Forge Motorsport products come with a limited lifetime warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.

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.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
