• 2 Fuel rails

What This Product Does

The six adapters provide the interface between an earlier two-bolt Porsche 911 cylinder head and a later 964 or 993 3.6 intake manifold. Each adapter is machined to suit the selected cylinder-head port diameter and transitions to the manifold's 42mm bore.

A compact overall height helps retain clearance around the throttle body, idle air control valve and the upper area of the engine bay. The injector position is aligned above the existing CIS injector relief in the intake port. 

Functions

• Connects a 964 or 993 3.6 intake manifold to an earlier two-bolt cylinder head
• Supports conversion from CIS or an earlier injection arrangement to EFI
• Positions the injector over the original CIS injector-port relief
• Provides a tapered transition to the 42mm intake-manifold bore
• Maintains a short installed height for engine-bay clearance
• Accommodates Bosch injectors with 14mm O-ring fittings

Technical Details

• Five-axis CNC-machined high-grade aluminium construction
• Protective anodised finish
• Designed for Porsche 911 2.7L, 3.0L and 3.2L two-bolt cylinder heads
• Fuel-rail spacers are marked for adjustment to long, medium or short Bosch injector formats
• Manifold-side transition is designed for a 42mm bore

Components Not Included

Intake manifolds, rubber joining sleeves, fuel injectors and hose clamps are not supplied with the base adapter kit.

Installation Notes

This component forms part of a custom EFI installation rather than a complete conversion package. Confirm the cylinder-head port diameter, injector length, manifold specification and clearance around the throttle and idle-control components before assembly. Engine-management hardware, fuel delivery components and calibration must be selected for the completed installation.

Adapt Motorsport electronic individual throttle body (eITB) kit for the Porsche 964 and 993. Six individual throttles are operated as two independently controlled cylinder banks by a modern drive-by-wire engine-management system.

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.

Configuration Notes

• Three-bolt versions can accommodate air conditioning
• A 993 retaining power steering and air conditioning requires short injectors and a low-profile fuel fitting
• This electronic ITB system is specified by Adapt Motorsport for off-road and racing applications only

Electronic individual throttle body kit by Adapt Motorsport for classic Porsche 911 engines. This drive-by-wire system uses separate throttle bodies for all six cylinders, with independent electronic control for the left and right cylinder banks.

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 eITB kit electronically controls airflow to each cylinder without conventional throttle cables or linkages between the pedal, cylinder banks and individual throttles. Its two direct-drive motors incorporate throttle-position sensing, allowing a suitable aftermarket ECU to manage idle opening, pedal sensitivity and bank-specific throttle operation.

Functions

• Controls six individual throttle bodies through two independent drive-by-wire motors
• Allows throttle sensitivity and pedal response to be calibrated within the ECU
• Uses the electronic throttles to regulate idle airflow without a separate idle-control valve
• Provides individual air-bypass adjustment for cylinder balancing
• Supplies vacuum connections for balancing equipment, brake servos and other vacuum-operated devices
• Supports compatible ECU strategies such as torque management, launch control and automatic throttle blipping

Technical Details

• Base kit includes six pre-assembled individual throttle bodies, two DBW motors with integrated sensors, six intake adapters, two fuel rails and two throttle-driver connector kits
• Internal throttle-position sensors use dual-channel redundancy, with independent motors and sensing for each cylinder bank
• Fuel rails are designed for short EV14 fuel injectors
• Construction includes stiff throttle couplings, sealed roller bearings and thermal-barrier spacers between the throttle assemblies and cylinder heads
• Selectable 2-bolt and 3-bolt configurations are offered with multiple port and butterfly diameters; intake-manifold and tapered velocity-stack adapter options are available
• Compatible control systems must operate two independent throttle motors and provide six analogue sensor inputs plus two complete four-pin half-bridge driver outputs

Why Replacement Matters

This kit is intended for EFI conversions and modified classic Porsche engines requiring electronically managed individual throttles. Removing mechanical cables and cross-bank linkages eliminates their adjustment, backlash and friction points while giving the calibrator direct control over throttle opening. Installation, balancing and mapping should be completed by a specialist familiar with dual-DBW ITB systems. Adapt Motorsport identifies MoTeC M150, Emtron KV8 and ECUmaster Pro 8 as suitable examples, although ECU compatibility must be confirmed for each installation. Fail-safe DBW functions, engine limp modes and dual wideband oxygen sensors for closed-loop tuning of both banks are required or recommended as applicable.

Important

• Two-bolt versions are not compatible with the standard air-conditioning compressor
• This eITB system is specified by Adapt Motorsport for off-road and racing applications only

V-Rib Belt Crank Pulley and Tensioner Upgrade  Kit by Adapt Motorsport replaces the original V-belt arrangement while retaining the standard fan drive ratio.

Fits:

• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50

What This Product Does

This conversion uses a multi-rib belt to transfer drive to the cooling fan and alternator. The eccentric-mounted idler pulley provides controlled tension adjustment and reduces belt whip, addressing limitations that can affect the original V-belt arrangement during fast engine-speed changes, hard driving or operation with a high-current alternator.

Functions

• Transfers crankshaft rotation to the fan and alternator through a V-rib belt
• Provides precise belt-tension adjustment through the eccentric idler pulley
• Reduces belt whip during rapid changes in engine speed
• Retains the original fan drive ratio
• Provides pulley markings for base and cam timing work

Technical Details

• Precision-machined from high-grade aluminium
• Black anodised finish
• Component strength validated using finite element analysis
• Timing notches at 0, 5, 120 and 240 degrees
• Standard kit includes the V-rib crank pulley, eccentric idler pulley kit, fan pulley and fan belt
• Standard+Trigger kit adds a lightweight 36-1 crank trigger disc for a crankshaft position sensor used in EFI conversions

Symptoms Addressed

• Original V-belt being displaced during rapid engine-speed changes
• Belt slip when driving a high-current alternator
• Accelerated belt wear caused by slipping
• Excessive belt tension being used in an attempt to prevent slip
• Loss of charging voltage or cooling-fan drive following belt displacement or failure

Why Replacement Matters

A displaced or slipping fan belt can interrupt alternator and cooling-fan operation. The V-rib design increases the available belt contact area, while the adjustable idler allows tension to be set without relying on excessive belt loading that may shorten alternator-bearing life.

What This Product Does

The regulator controls fuel pressure within the injection system. Its adjustable design allows the required operating pressure to be set for the applicable factory system or a compatible tuned installation.

Functions

• Mounts directly to the factory fuel rail using an O-ring connection
• Provides adjustable fuel pressure from 2.0 to 5.0 bar
• Connects to the return hose through an 8 mm barb outlet
• Allows increased fuel pressure where required by a compatible 944 Turbo tuning chip
• Supports straightforward replacement of specified Bosch and Porsche regulators

Technical Details

• Adjustment range: 2.0–5.0 bar
• Fuel return connection: 8 mm hose barb
• Fuel-rail connection: direct O-ring fitting
• Supplied with regulator body, adjustable regulator, outlet fitting, cap screws and lock washers
• Tested by Adapt Motorsport with Bosch 044 fuel pumps; the maximum supported flow rate has not been established
• The regulator is not supplied pre-set and must be adjusted on the vehicle using a suitable fuel-pressure gauge and fuel-rail adaptor

Symptoms of Fault

• Fuel leakage around the original regulator
• Running problems caused by regulator failure
• Difficulty obtaining the required fuel pressure during engine tuning

Why Replacement Matters

Many original regulators fitted to these models are now several decades old and may leak or cease to regulate correctly. Replacement restores an adjustable pressure-control point while retaining a direct connection to the applicable factory fuel rail. Final pressure must be measured and set after installation to match the vehicle and engine specification.
