All the benefits of the current Big Mouth 102mm Throttle Body(TM) are now available for drive-by-wire applications, thanks to the new FAST(TM) 102mm Electronic Throttle Body for GM LS Engines. This new electronic throttle body provides a huge increase in airflow over stock –...

These throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle...

The Fast Big Mouth 102mm throttle body provides increased airflow through a smoother offset blade pivot. In addition we increased blade thickness to eliminate deflection and a beefed up linkage and spring mechanism.

Our Big Mouth 92mm Throttle Body for GM LS features a black wrinkle powder coating finish along with an improved throttle blade and pivot. In addition, our throttle body improves throttle response and eliminates blade deflection.

Fuel Rail Adapter Kit, MANIF T O LS2 INJ

This replacement rope seal is designed to ensure that the upper shell of your LSX 90 or 92mm intake manifold seals properly to the lower shell.

This throttle position sensor is the same as a GM LS design TPS. This TPS features a three-pronged metripak connector, and is used on FAST Big Mouth Throttle Bodies including the 102 and 92mm LS as well as the 87mm Coyote and HEMI.

Throttle Body Seal, LSX To use W/90MM TB

These gaskets are designed to provide a seal between the LSX 92mm intake manifold and LS1, LS2 and LS6 cylinder heads.

FAST Manifold Inner Shell LSX Only

FAST Manifold Upper Shell 78MM Throttle Body

This adapter connects an older IAC with a 2x2 weatherpack connection to a later model EFI harness that uses a Metripack/LS connection such as our EZ 2.0 or XFI Sportsman

These sensors, by monitoring intake manifold vacuum, measure the amount of load being placed on the engine. The MAP sensors relay engine load output to the ECU, which in turn adjusts fueling for optimum performance and economy.

The throttle position sensor bolts to the throttle blade shaft and relays throttle opening/closing information to the system ECU. The TPS is constructed of high resistance material with a sensitive rotator for accurate throttle position measurement.

This cable is connects directly to the FAST XFI computer with a weatherpack style connector. Features a Serial Bus style connector on Laptop side.

FAST 4 Barrel Throttle Bodies incorporate tapered and radiused throttle bores and precisely machined progressive linkage for smooth throttle operation and unparalleled airflow. More airflow equals more horsepower.

Wiring Harness, Fast 4-Cyl Fue L Injector

This main harness is used with Classic Systems on 4 cylinder applications

This harness provides a universal connection to sensors etc for our Classic System

This IAC is an IAC designed for applications that require relocating the IAC such as 8 stack injection systems. This IAC valve has a filter so there is no concern for debris entering the engine through the remotely mounted IAC Valve

Considered Early/TPI Design Not LS Series/Late. This design is not used on EZ 1.0 or EZ 2.0 Throttle Bodies. Requires a male 2x2 weatherpack to a 4 flat metripack adapter to adapt to a harness designed for 'late model/LS' This sensor is commonly found...
