Fuel injection throttle body kit with air horns - Without fuel injectors



Fits:
Porsche 911 2.0ltr - 1965 to 1968
Porsche 911 2.2ltr - 1969 to 1971

Sizes Porsche 911 intake manifolds
Carburetor/Bosch MFI Ø32mm engine side - Ø40mm ITB side. Recommended for early 2.0ltr / 2.2ltr engines

Injectors options that can be used - 260cc / 300cc / 380cc / 420cc / 480cc / 520cc

This is a direct replacement kit for replacing carburetors while keeping the OEM look in your engine bay. 

The intake manifolds and riser plates are manufactured out of a single piece of 6082 aluminum and come in 2 styles. These differ in design due to the shape of the mounting flange for the cylinder head. The intake manifold can be used as replacement parts for the OEM part when damaged or has to be replaced*.
The ITBs are manufactured out of cast aluminum, whist the fuel rails are made out of aluminum 6060 extrusion profile and come with AN6 ORB connection for the fuel lines. The direct mount fuel pressure regulator is directly mounted to the fuel rails, so in this case you don’t need to drill additional holes in the engine bay for mounting a fuel pressure regulator.
The throttle linkage and all mounting hardware is made from stainless steel and the pivoting point of the throttle linkage is a ball and socket design for smooth operation. The levers allow you to adjust and finetune mechanical movement of the ITBs

The dimensions of the assembly are the same as the OEM carburetor setup and the riser plate comes with same mounting holes as the OEM carburetors, in this way you are able to use the OEM air filter box and OEM airhorns. Also the riser plates come with mounting options for an air intake temperature sensor, this is nicely hidden away between the ITBs. The diameter for the ITBs in the riser plate is 45mm. There is also an option for using airhorns, In this case you don’t need the riser plates.

The crank sensor and trigger wheel kit are additional and this type of kit is needed when using ITBs like these. Besides switching to ITBs you will need a stand alone ECU to get the fuel injection to work. Our kit only works with engines like the 3.0ltr that came with a “ big distributor”. You can leave the distributor or you can remove this unit when you are going to use a discoil type of ignition. In for case an adapter is included in the crank sensor kit. The pulley comes in 2 dimensions to choose from, a Ø116mm pulley and Ø126,5mm pulley.

Fuel injectors, fuel lines, standalone ECU, wiring harness are NOT included in the kit.

*In case of using as a replacement part 3 mounting holes for the carburetors or ITBs need to be re thread with a timesert or helicoil. Otherwise it is impossible to mount a threaded stud.

Kit Includes
2 x Full billet, hard anodised intake manifolds
6 x ITB complete with lever assembly
6 x Airhorns 45mmØx30mm
2 x Fuel rail with mounting hardware
1 x Throttle linkage with 2 throttle connection rods
1 x Direct mount fuel pressure regulator
2 x Riser plates with 1 air temperature sensor (for use with OEM air filter box)
1 x Crank sensor and trigger wheel kit (optional)
All needed gaskets and mounting hardware.

Inlet manifold adaptor kit, 2 bolt cylinder head for EFI (electronic fuel injection) conversion . 

Fits:
Porsche 911 / 911S 2.7ltr - 1974 to 1977
Porsche 911 SC - 1978 to 1983
Porsche 911 3.2 Carrera - 1984 to 1989

These adapters are used to modify the 2.7ltr / 3.0ltr / 3.2ltr Porsche 911 2 bolt cylinder head engines to the later 964 / 993 3.6ltr intake manifolds when converting to EFI.  

CNC machined on a 5 axis machine to our exacting tolerances and finish and anodised dark grey these are custom machined to match your port diameter and tapered to fit up to the 42mm inlet manifold port size.

The short adapor height maintains the overall height of the intake set, reducing the interference between the idle air control, the intake boot and the top of the engine bay insulation.  The factory plastic 3 bolt 964 stacks are too tall, and adding an adapter spacer would make the manifolds not fit at all.

This design permits the use of the standard 964 fuel injectors and fuel rails so positions the injector over the same relief in the intake port for the original CIS injector, ensuring proper atomisation of the injector spray into the intake port.

Key Features:
Precision machined from high grade aluminium
Anodized finish
Fits all Bosch 14mm O-ring fuel injectors
Fuel rail spacers are marked for easy cutting to suit long, medium or short injector types.

Kit Includes:
6 x CNC aluminium adapters
4 x Spacer/Posts for fuel rail 
4 x Bolts to suit standard full length Bosch injectors
12 x Nuts and washers 

Fuel rails not included in kit

34mm / 40mm / 41mm / 42mm adaptors are made to order. Please allow 4-5 weeks for delivery

Inlet manifold adaptor kit, 2 bolt cylinder head to 996 GT3 inlet manifold. 

6 x manifold adaptors (no fuel rail)

Fits:
Porsche 911 / 911S 2.7ltr - 1974 to 1977
Porsche 911 SC - 1978 to 1983
Porsche 911 3.2 Carrera - 1984 to 1989

These adapters are used to adapt the 2.7ltr / 3.0ltr and 3.2ltr Porsche 911 2-bolt cylinder head engines to take the 996 GT3 intake manifolds when converting to EFI.  
CNC machined our exacting tolerances and finish and anodised dark grey these are custom machined to match your port diameter and tapered to fit the 49mm bore of the GT3 inlet manifold.

The short height maintains the overall height of the intake set, reducing the interference between the idle air control valve, the intake boot and the top of the engine bay insulation.  

This design permits the use of the AMS fuel rails, and positions the injector over the same relief in the intake port for the original CIS injector, ensuring proper atomisation of the injector spray into the intake port.

Key Features:
Precision machined from high grade aluminium
Anodized finish
Fits all Bosch 14mm O-ring fuel injectors
Fuel rail spacers are marked for easy cutting to suit long, medium or short injector types.

Kit includes:

• CNC aluminium adapters x 6
• Spacer/Posts for fuel rail x 4
• Bolts to suit standard full length Bosch injectors x 4
• Nuts and washers for cylinder head studs x 12

What's Not Included:
Fuel rails, manifolds, rubber joiners, injectors, hose clamps pictured are not included in the sale.

Inlet manifold gasket. 
OE Match replacement gasket built to meet original Porsche specifications, designed for the Porsche 911 Carrera 3.2L (1984–1989). This gasket provides a perfect seal between the intake manifold and the cylinder head, ensuring that air and fuel are delivered precisely to each combustion chamber.
Sold each, 12 required per engine.

Fits:
Porsche 911 Carrera 3.2L 1984 - 1989 
Engine code: 93020, 93025, 93026
Please note: NOT for 930 Turbo

Diagram Ref No 6.

•  Position: Between intake manifold and cylinder head
•  Function: Seals intake air passages, prevents vacuum or boost leaks
•  Replacement Interval: During intake removal, rebuild, or if leaks or idle issues occur
•  Benefits: Restores airtight sealing, smooth idle, and optimal air-fuel efficiency

Keep your classic Porsche running flawlessly with the OE Match 93011019714 Inlet Manifold Gasket. Built to OEM standards for the 911 Carrera 3.2, it seals the intake manifold to the cylinder head for airtight, efficient performance. Replace worn or leaking gaskets to restore smooth idle, strong power, and factory reliability.

Over time, intake gaskets harden and lose elasticity due to constant exposure to heat, pressure, and fuel vapours.

This can lead to:
•  Air or vacuum leaks affecting mixture balance and idle quality.
•  Reduced power, poor throttle response, or “hunting” idle.
•  Possible lean running and increased engine wear.

Replace during:
•  Intake manifold removal or service.
•  Engine rebuilds or top-end overhauls.
•  Any time vacuum leaks or air-fuel irregularities are detected.

Replacing with an OE Match gasket restores proper sealing, consistent idle, and smooth power delivery — crucial for maintaining your Porsche’s precision performance.
