Designed for air-cooled six-cylinder Porsche engines from 1965 to 1998, PMO individual throttle bodies combine the classic appearance and response of traditional carburettors with the accurate fuel control and tuning possibilities of modern EFI.

The Black Anodized “R” finish gives the throttle bodies a purposeful vintage competition appearance, making them particularly suited to performance, restomod and motorsport-inspired Porsche engine builds.

Inlet Manifolds, Fuel Injectors and Throttle Position Sensor (TPS) are Not Included

Please note that inlet manifolds, fuel injectors and the TPS shown in product imagery are for reference and are not included with the kit.

What Does the PMO EFI Throttle Body Kit Do?

PMO individual throttle bodies replace carburettors or the existing induction system as part of a complete electronic fuel injection conversion.

Each cylinder receives its own throttle bore, providing direct and responsive airflow. Fuel is delivered through individual injectors controlled by a compatible programmable ECU.

When correctly installed and tuned, benefits can include:

• Sharper throttle response
• Precise electronic fuel control
• Improved engine tuneability
• Better cold starting and driveability
• Accurate control of air/fuel ratios
• Potential improvements in performance and fuel efficiency
• Individual throttle response for each cylinder
• Classic competition appearance with modern EFI technology

40mm, 46mm or 50mm – Which Size?

PMO offers three throttle body sizes to suit different air-cooled Porsche engine specifications.

• 40mm – Ideal for smaller-capacity and road-focused engines where good air velocity, throttle response and low-to-mid-range performance are important.
• 46mm – Suitable for larger-capacity, fast-road and modified engines requiring increased airflow while maintaining excellent throttle response.
• 50mm – Designed for highly modified, large-capacity and competition engines where maximum airflow and high-RPM performance are required.

Correct sizing depends on engine capacity, cylinder heads, camshafts, compression ratio, intended RPM range and power requirements. Consult your engine builder when selecting the appropriate size.

Precision PMO Construction

PMO EFI throttle bodies are precision CNC machined and hand assembled in Anaheim, California using aerospace-grade materials.

Sealed ball bearings provide durability, while the one-piece throttle shaft maintains accurate alignment for smooth and consistent throttle operation.

Tapered 52mm intake throats improve airflow into the throttle bodies, while billet fuel rails accommodate Bosch-style fuel injectors.

EFI Management Compatibility

PMO EFI throttle bodies can be used with programmable engine management systems including Haltech, MegaSquirt, MoTeC and other suitable aftermarket EFI controllers.

The ECU must be correctly configured and tuned for the individual engine specification.

Injector size, fuel pressure, sensors and ECU configuration should be discussed with your engine builder or EFI system supplier before installation.

Converting from Carburettors to EFI

A carburettor-to-EFI conversion requires a suitable high-pressure fuel system in addition to the throttle bodies.

A fuel pump capable of approximately 60 psi is required. The Walbro GSL393 external universal inline fuel pump, rated at approximately 160 LPH, is one suitable option. Another correctly specified 60 psi EFI fuel pump can also be used.

Fuel lines, filters, pressure regulation and associated components must be suitable for EFI operating pressures.

Fits

• 
  

What This Product Does

The eITB assembly replaces conventional pedal cables and cross-bank throttle linkages with direct electronic actuation. A compatible aftermarket ECU can regulate each bank, control idle through the throttle motors and tailor throttle opening to pedal position and operating conditions.

Functions

• Controls six individual throttles using two independent drive-by-wire motors
• Permits ECU calibration of pedal response and throttle sensitivity
• Manages idle airflow without requiring a separate idle-control valve
• Provides individual bypass adjustment for balancing cylinder airflow
• Supports suitable ECU strategies including torque control, launch functions and automatic rev matching
• Removes mechanical cables and cross-bank linkages that can develop friction, flex or free play

Technical Details

• Six pre-assembled individual throttle bodies with two electronic motors and integrated position sensing
• Independent motors and dual-channel throttle-position sensing for the left and right cylinder banks
• Two fuel rails designed for short EV14 fuel injectors
• Six intake adapters and two throttle-driver connector kits supplied according to the selected configuration
• High-stiffness throttle couplings, sealed roller bearings and thermal-barrier cylinder-head spacers
• Vacuum connections for balancing instruments, brake servos and other vacuum-operated equipment

Installation and ECU Requirements

Installation, synchronisation and calibration should be handled by a specialist experienced with individual throttles and dual-motor DBW systems. The ECU must control two independent throttle motors and provide six analogue sensor inputs plus two complete four-pin half-bridge motor-driver outputs. Appropriate DBW fail-safe operation and engine limp modes are required. Adapt Motorsport identifies the MoTeC M150, Emtron KV8 and ECUmaster Pro 8 as suitable examples, although compatibility must be checked for each installation. Dual wideband oxygen sensors are recommended for closed-loop calibration of both cylinder banks, particularly at idle.
