Forge Motorsport adjustable turbocharger actuator for Nissan 200SX S14

The Forge Motorsport adjustable turbocharger actuator is designed for the Nissan S14 with a bent actuator rod.

It enables precise adjustment and control of boost pressure. It is supplied as standard with a green-marked spring, while different spring rates are also available for standard and modified vehicles.

• Manufactured from 6026-grade aluminium
• Vehicle- and turbocharger-specific
• Actuator rod made from 303-grade stainless steel
• Standard diaphragm sealing
• Optional piston internals are available and require less maintenance
• Fluorosilicone diaphragms reinforced with Nomex fibres
• Laser-cut stainless steel brackets where required
• Service and adjustment kits are available

The stated spring pressures represent the minimum regulated pressure. On modern engines with electronic control via the ECU or solenoid, the mechanical spring specification does not necessarily correspond directly to the target boost pressure. When selecting a spring, consider the engine specification and the planned level of modification.

The actuator is supplied as standard with a green-marked spring. To use the FMPACTUN spring adjustment kit, the Type 2, 049 diaphragm version must be selected.

For T2 series springs, the specified marking is FMAS049.

The kit includes:

• 1 × FMACS14B actuator
• 1 × Forge sticker

Suitable for: Nissan 200SX II (S14).
