Electronic Throttle Conversion Kit with GT3 Manifold. Porsche 911  ❭  AMS90501

This naturally aspirated GT3 manifold electronic throttle conversion kit by Adapt Motorsport is designed for classic Porsche 911 engines with two-bolt cylinder heads. 

Fits

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50

What This Product Does

The kit adapts large-volume 996 GT3-style intake manifolds and Bosch electronic throttle control to compatible air-cooled Porsche 911 engine builds. Adapt Motorsport intake components account for the shorter cylinder spacing of air-cooled engines and provide the fuel-rail, resonance-flap and vacuum-control hardware needed to complete the intake assembly.

Functions

• Regulates intake airflow through an 82mm Bosch electronic throttle body
• Connects GT3-style intake hardware to two-bolt air-cooled cylinder heads
• Supports short, medium or long EV14-style fuel injectors using the appropriate rail spacers
• Controls the intake resonance flap through a vacuum canister, solenoid and check valve
• Provides vacuum connections for the brake booster, idle-air bypass and supporting systems
• Measures manifold pressure and intake temperature through a Bosch T-MAP sensor

Technical Details

• 996 GT3-style intake manifold port diameter: 49mm
• Two-bolt adapters: 40mm or 42mm ports for 2.7, 3.0 and 3.2 engines
• Bosch electronic throttle body diameter: 82mm
• Standard Bosch T-MAP sensor rating: 1.15 bar; a 3.0-bar version is offered separately
• AMS manifolds use cast-aluminium construction, while the resonance flap and intake T-piece are CNC-machined and black anodised

Base Kit Contents

• AMS high-flow intake T-piece with vacuum and T-MAP sensor connections
• AMS fuel rails with fittings
• Bosch 82mm electronic throttle body and connector kit
• AMS CNC-machined resonance-flap assembly with sealed roller bearings
• Bosch 1.15-bar temperature and pressure sensor with connector
• Throttle, resonance-flap and intake-adapter sleeves with hose clamps
• Vacuum canister, solenoid, check valve, electrical connector and hoses
• Required fasteners and fittings

Configuration Information

Separate versions accommodate two-bolt and three-bolt cylinder heads, with the relevant adapter port sizes. Each configuration can be supplied either with or without a pair of AMS GT3 intake manifolds, so the cylinder-head pattern, port diameter and manifold requirement must be confirmed before selection.

FAQs

• Is the electronic throttle body included?
  Yes. Every base kit contains the Bosch 82mm electronic throttle body and its connector kit.
• Are intake manifolds supplied?
  This depends on the chosen configuration. Adapt Motorsport offers versions both including and excluding the pair of AMS GT3 intake manifolds.
• Does the system require calibration?
  Yes. The electronic throttle, T-MAP sensor, injectors and resonance-flap controls must be configured within a compatible engine-management system.
• Which cylinder-head patterns are supported?
  Two-bolt versions suit 2.7, 3.0 and 3.2 engines, while three-bolt versions are intended for 964 and 993 3.6-litre applications.
