Porsche 964 - 1989 to 1994
Porsche 993 - 1994 to 1998
Silverlake Projects' complete Drive-by-Wire (DBW) intake system, designed specifically for 964 and 993 engines to be converted to DBW (drive by wire) throttle body.
Our system includes:
- 6 precision-engineered runners crafted from anodized structural aluminum
- 2 anodized fuel rails, also made from structural aluminum for durability and performance
- Dual GT3-style intake manifolds in carbon fiber for weight reduction and strength
- Intake T-tube in glass-reinforced thermoplastic, compatible with a 82mm DBW throttle body
- Resonance flap or resonance flap delete tube in glass-reinforced thermoplastic, complete with a vacuum actuator
- 6 high-temperature silicone couplers for the manifold-to-runner connections
- 4 high-temperature silicone couplers for the manifold-to-T-tube/resonance flap connections
- TMAP sensor for accurate air intake measurements
- Vacuum reservoir for optimized engine performance
- All mounting hardware made from lightweight titanium alloy
Inlet port sizes: 42mm
Weighing just 5.5 kg (12 lbs), our intake system is nearly half the weight of the stock 964 intake, which weighs 11.5 kg (25.3 lbs), offering a substantial weight savings for enhanced performance
Why our system?
- 50% lighter than stock. Lighter than most systems given use of carbon fiber, thermoplastics, and titanium.
- Direct mount of fuel rail to the runner for perfect injector press fit.
- CNC machined PTFE inserts in between the cylinder head and the runner for a superior insulation from the heat from the cylinder heads, especially when in idle and street applications.
- Custom nitrile O-rings in between the runner and the cylinder head, and the intake T and throttle body for a perfect seal
- Silverlake’s precision-molded OEM+ silicone sleeves with a much higher temperature resistance than rubber, offering a perfect fit with the opposing components for better airflow, and an unmatched appearance.
- All mounting fasteners in Tin coated titanium alloy, for reduced weight and un unbeatable appearance
- Your choice between 82mm or 92mm drive by wire throttle bodies, the latter offering 25% more surface for high displacement high performance applications

This kit is a modern update to the 964 (911) ignition system. This system takes the management of the car into the digital age and allows greater control over ignition and fueling.
The kit will replace your restrictive old fashioned air flow meter (barn door) with a modern MAP sensor managed by intake pressures.
The kit is delivered ready to use with a PPT ignition map. We have maps for 3.6 and 3.8 conversions, and either can be pre-installed for you.
Our latest kit now comes with an upgraded ECU and can run a wide band sensor (oxygen sensor).
Our kits include this capability but the sensor needs to be ordered separately.
While developing the upgraded ECU we also changed our intake pipe; this now works with the factory airbox, gives a stock appearance in the engine bay and houses the map sensor and air temp sensor out of sight.
Kit includes:
• Delta 700 ECU
• Direct plug in wiring loom
• Map Sensor and air temp sensor
• Air intake pipe
• 6 Bosch injectors
• Vacuum pipe and T connector
• Support and service by PIE Performance
• Can Bus data connection tool
All our kits are 100% reversible, with no need to drill or alter components, we utilise what already exists

Patented technology that helps to increase air flow dramatically thus minimising air flow separation and reduces turbulence, resulting in higher volumetric efficiency.
This pristine technology with Knife-edged butterflies has improved inlet airflow and performance significantly. With the individual Throttle blades very close to the inlet valves, the engine and Throttle response are vastly improved. Along with this, we have also found an impressive increase in Horsepower, Torque, Driveability, and an incredible mechanical soundtrack.
Throttle Bodies come fully assembled and ready to bolt directly to the Cylinder Heads, with the following parts included:
• Anodised Aerospace Grade 6082/T6 Billet Aluminium "Shaft-less" Individual Throttle Bodies.
• SLS 3D Printed custom curved Inlets for bonnet clearance around the standard 964/993 models with electronic spoilers.
• Aluminium Ram Pipes & Assembly Tool.
• Throttle Position Sensor (TPS).
• Billet Aluminium Fuel Rails, Including PICO 377cc Fuel Injectors.
• Thermal Insulation Gaskets.
• Throttle Linkage System which connects directly to the existing OEM cable pick-ups.

Fits:
Porsche 964 Carrera 2 / Carrera 4 - 1989 to 1994
This is a direct replacement kit for converting your Porsche 964 engine to ITBs like the Porsche RSR using airhorns
Kit includes:
6 x Full billet, hard anodised ITB with a stainless steel lever assembly
6 x Thermo barrier gaskets
2 x Fuel rail with mounting hardware
1 x Throttle actuator hard anodised with 2 throttle connection rods manufactured out of stainless steel
1 x Throttle position sensor with mounting hardware
All the needed mounting hardware and fittings.
ITBs in 2 different sizes:
- Tapered ITB: ∅42mm-∅41,5mm (∅42mm is the butterfly valve size, ∅41,5mm is the intake port diameter)
- Tapered ITB: ∅48mm-∅41,5mm (∅48mm is the butterfly valve size, ∅41,5mm is the intake port diameter)
All parts of this kit are made out of a single piece 6082 aluminum and are anodized or hard anodized to make them more wear resistant.
The mounting hardware and other parts are made out of stainless steel, the fuel rails out of 6060 aluminum extrusion profile and come with AN6 ORB connection for the fuel lines.
The throttle linkages and all mounting hardware are made out of stainless steel and the pivoting points of the throttle linkage are made with ball and socket design for smooth operation. The throttle actuator has a bearing inside for a long lifespan.
You are also able to use the OEM throttle connection cable but you will need to cut the rigid part at the end of the cable and mount a cable nipple for connecting the cable to the throttle actuator. All aluminum parts of the throttle actuator assembly are manufactured out of 6082 aluminum and are hard anodized.
The levers allow you to adjust and finetune mechanical movement of the ITBs
Fuel injectors, fuel lines, standalone ECU, wire harness are NOT included in the kit but work together
