E-Throttle DBW Conversion Kit for Porsche 964/993 Inlet Manifolds. Porsche 911 / 964 / 993  ❭  AMS9050

This Adapt Motorsport E-Throttle conversion kit replaces the original throttle centre section fitted to Porsche 964 and non-VarioRam 993 intake manifolds. It combines a Bosch 74mm electronic throttle with a CNC-machined resonance tube assembly and Bosch T-MAP sensing.

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 993 (911) C2 1994-95
• Porsche 993 (911) C4 1994-95
• Porsche 993 (911) C2S 1994-95
• Porsche 993 (911) C4S 1994-95

What This Product Does

The kit converts the 964 / non-VarioRam 993 inlet manifolds from mechanical or cable-operated throttle control to electronic drive-by-wire operation. When used with a suitable aftermarket ECU and correctly calibrated, the throttle can also perform electronic idle-control functions without the factory idle-air bypass valve.

Functions

• Replaces the original Porsche throttle centre section.
• Provides electronically managed throttle control.
• Combines intake-air temperature and manifold-pressure measurement through a Bosch T-MAP sensor.
• Removes ageing throttle cables or mechanical linkages from the control system.
• Supports ECU-managed idle control when correctly configured.
• Allows compatible engine management to support features such as cruise control, automatic throttle blipping, traction control and boost control.

Technical Details

• Bosch 74mm electronic throttle with connector kit.
• CNC-machined aluminium throttle intake adapter.
• CNC-machined aluminium resonance tube assembly with flap, sealed roller bearings and vacuum actuator.
• Choice of 1.15 bar T-MAP sensor for naturally aspirated applications or 3.0 bar sensor for turbo applications.
• T-MAP connector kit, throttle and sensor fasteners, and vacuum hose included with the centre-section kit.
• The vacuum kit is not included with the centre-section configuration.

Kit Includes:

• CNC machined aluminium Throttle intake adapter
• CNC machined aluminium resonance tube assembly including flap assembly, sealed roller bearings and vacuum actuator
• Bosch 74mm Electronic Throttle and connector kit
• Bosch T-MAP sensor 1.1 bar or 3.0bar as standard options, with connector kit
• Fasteners for throttle and T-MAP.
• Vacuum hose 
  
  

Additional Parts Required

• Vacuum solenoid and canister.
• Air filter and suitable adapter.
• Rubber sleeves and hose clamps for the intake-manifold ports; compatible original Porsche components may be reused.
• A compatible electronic accelerator pedal, aftermarket ECU and appropriate wiring, programming and safety calibration.

Optional Components

• 964/993 vacuum kit and mounting hardware.
• 964/993 electronic accelerator pedal kit.
• 993 adapter for retaining the factory rubber intake, airflow meter and airbox.
• 964 adapter for the factory rubber intake and airbox, including an airflow-meter delete kit.
• 964/993 air-filter adapter kit or advanced fuel rail kit.

Why Replacement Matters

Converting to drive-by-wire removes cable drag, stretch and resistance from multi-part mechanical linkages. It also enables the fitted engine-management system to control throttle movement and idle behaviour electronically. Installation and calibration should be completed by an experienced technician using suitable ECU safety strategies.
