Turbosmart FCD-1 Pneumatic Fuel Cut Defender Universal Turbo EFI Fitment
The Turbosmart FCD-1 Pneumatic connects between the boost source and fuel pressure regulator to divert pressure at set boost levels preventing ECU fuel cut in turbocharged EFI vehicles. It fits universally on models including Subaru Impreza WRX STI Mitsubishi Lancer Evolution and Nissan Skyline with boost-activated fuel cut systems. This device allows running higher boost safely by tricking the ECU into lower pressure readings while maintaining precise fuel delivery.
Key Features
- Adjustable Activation Pressure: Tune activation from 5 to 30 psi using included springs for exact boost threshold matching your setup
- Pneumatic Solenoid Design: Direct boost-referenced operation without electronics for consistent performance under extreme conditions
- 3 x 1/8 NPT Ports: Standard fittings ensure straightforward plumbing into vacuum boost lines and regulators
- Brass and Aluminum Construction: Durable materials resist corrosion and handle high pressures up to 50 psi continuously
- Compact Size: Measures 2.2 x 1.5 x 1.2 inches weighing just 2.4 ounces for easy mounting in tight engine bays

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
