You asked for it, we designed it, redesigned it and perfected it. After years of design and development, we are excited to introduce our latest and greatest product, the Adapt Motorsport Electronic Individual Throttle Body Kit (eITB) for classic Porsches. We are setting the benchmark in innovation, there are no direct comparable products in the market, and it is the cleanest, most simple and discrete system available.
Available in 2 bolt for 2.7, 3.0, 3.2 engines and 3 bolt for 964/993 3.6 engines in a variety of sizes and adapter options for almost every intake system available on the market. Compact, precision engineered to very tight tolerances for perfect operation easy setup and flexibility for current and future upgrades this is the one ITB system every owner needs.
Why Electronic? Drive by wire throttles are nothing new, almost every modern car is equipped with them, they allow for precise throttle control and the ability to simplify intake systems with fewer parts, wiring and modules to control.
- No separate idle air control required, the electronic motors can adjust idle air.
- Complete flexibility with throttle sensitivity mapping in the ECU. ITBs are known to be sensitive to throttle position, this can be a good or a bad thing depending on the application, engine specifications and environmental conditions. Throttle opening can be tuned for different pedal positions, and even have several maps for around town smooth driving, to aggressive canyon or circuit racing.
- No cables or linkages to break, go out of adjustment, create drag and friction
- Safe and redundant sensing, reduces the risk of stuck throttle engine over revs. The ECU will detect stuck throttle and engage safe engine rev limits/limp modes.
- Advanced control of engine torque management for traction, launch and boost control for high performance applications.
- Auto blip and rev matching for sequential gearbox applications
Our system has been designed with many safety and performance considerations to be the absolute latest and best state of the art to provide high performance, reliable and consistent operation for the life of the product.
Advantages of the AMS E-ITBs
- No linkages or levers between throttle pedal and ITBs, or between right and left bank. Linkages allow for small amounts of error in backlash and flex, promoting inconsistencies in operation and variabilities in tuning and operation over time.
- Direct drive, no linkages between motors and each cylinder throttles.
- Internal throttle position sensors with dual channel redundancy
- Independent left and right motors and throttle position sensors
- Discrete motors hidden at the rear of the engine bay
- Proven and reliable OEM motors, sensors and components redundancy for full safety feature implementation in most modern ECUs.
- High stiffness throttle couplings
- Air bypass screws for individual cylinder balancing, without removing intake manifolds
- Vacuum ports for carb balancing tools/gauges
- Fuel rails to suit short EV14 fuel injectors
- Sealed roller bearings
- Thermal barrier spacers for mounting to cylinder head
- Integrated Vacuum ports for brake boosters and other vacuum control devices
- Pairs perfectly with our G model and 964/993 pedal sensors

Base kit Includes:
- 6x Individual Throttle Bodies, with 2x DBW motors with build in sensors, diameters as specified in the options. Pre assembled ready for installation.
- 6x Intake Adapters to suite 964/993 or GT3 Manifolds, as specified in the options
- 2x Fuel rails for short EV14 fuel injectors
- 2x connector kits for throttle drivers
Additional Information:
We recommend you have access to, or be a tuner familiar with dual DBW throttle systems for configuration as well as ITB systems for the installation, balancing and tuning of the system on a modern EFI ECU platform such as Motec, Emtron, ECUmaster.
We recommend the following ECU's. Others possible, but care should be taken to determine their suitability.
- Motec M150
- Emtron KV8
- ECUmaster Pro 8
The system, with pedal requires 6 analogue sensor inputs, and 2x complete (4x pins) half bridge driver outputs for the motors. It is required that the ECU has fail to safe DBW features and engine limp modes and the ability to control two independent throttle motors. Dual wideband sensors should be installed for close loop fuel tuning of left and right banks, particularly at idle.
We are not able to provide complete tuning advice to enthusiast mechanics/owners who are installing ITBs or DBW or EFI systems for their first time.
Delivery time is approximately 6 weeks.
2B versions not compatible with standard air conditioning compressor.
3B versions compatible with air conditioning compressor, 993 requires use of short injectors, if using power steering and low profile fuel fitting with air conditioning.
Our eITB products are for offroad and racing applications only.
