A Quick Look at Adapt Motorsport
Adapt Motorsport information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts
Choosing the Right Fit for Your Porsche
Where Adapt Motorsport is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons people choose these parts include functional upgrades to handling, drivetrain response, or track-oriented performance, usually combined with appropriate tyres, brakes, and alignment work.
- Common real-world symptoms that trigger replacement are performance fade, vague steering feel, brake heat issues, driveline movement, and general suspension fatigue or imbalance.
- Plan suspension and handling changes with an alignment in mind, and consider upgrading in stages so you can feel and measure what each change contributes.
- After any electrical or control-unit-related work, confirm basic checks such as battery health, good earth points, and that any new parts are correctly calibrated where required.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Electrical & Relays — These parts are usually replaced when an electrical function on your Porsche becomes unreliable, a safety-critical circuit stops working, or a repeated “no-start / no-power” issue is traced to switching or protection hardware. Real-world faults often involve heat, vibration, or marginal contacts, so a component may look fine but still fail under load.
- Start diagnosis with simple checks: correct fuse rating, relay seating, connector condition, and earth points before condemning major components.
- If a relay clicks but the circuit still does not work, treat it as suspect and confirm current flow and terminal condition.
Relays / Fuses — Relays and fuses are replaced when circuits fail outright or work intermittently, or when repeated fuse blowing and heat marks point to overload, shorts, or worn relay contacts. Owners often choose higher quality parts for critical circuits to reduce the risk of repeat electrical problems.
- Never uprate a fuse simply to stop it blowing; always find and fix the root cause to avoid wiring damage or fire risk.
- A quick practical check is to swap a suspect relay with an identical known-good unit and inspect the fuse/relay box for corrosion or heat damage.
Engine Electrical — Engine electrical components are typically changed when starting, charging, ignition, or sensor-related faults affect drivability and reliability. Symptoms include intermittent no-start, misfires, rough running, poor charging, warning lights, and heat-related failures that come and go.
- Use fault codes as a guide only; confirm issues with proper testing of power, grounds, and signal quality before replacing parts.
- Always check battery condition, main earth straps, and connector corrosion, as many “sensor faults” are caused by supply or grounding issues.
Engine Rebuild Parts — Engine rebuild parts are renewed during planned overhauls or when evidence points to wear inside the engine, such as low or uneven compression, heavy oil consumption, persistent internal leaks, abnormal noises, or contamination found in the oil system.
- Before committing to a rebuild, use tests such as compression, leak-down, borescope inspection, and oil/filter analysis to confirm internal wear or damage.
- When the engine is apart, it is common to replace chains, guides, tensioners, bearings (where applicable), seals, gaskets, and hard-to-access hardware to avoid repeat strip-downs later.

Adapt Motorsport Sync 2 ignition ref/sync sensor and V-rib conversion kit for Porsche 911 Carrera 3.2 models from 1984–89. It combines engine-position sensing with a multi-rib pulley drive for compatible 3.2 engine cases and consoles.
Fits
- Porsche 911 Carrera 3.2 1984–86
- Porsche 911 Carrera 3.2 G50 1987–89
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The kit supplies a compatible engine control unit with crank speed, crank angle and engine-cycle reference signals. A Hall-effect sensor reads the crank pulley trigger, including its missing-tooth reference, while the distributor-location sensor identifies the engine cycle. Together, these signals allow the ECU to determine whether the engine is on its compression or exhaust stroke for sequential fuel and ignition control.
Functions
- Measures crankshaft speed and angular position
- Provides a missing-tooth reference from the 36-1 trigger disc
- Produces an engine-cycle signal across each 720-degree cycle
- Enables the ECU to identify the compression stroke
- Supports sequential injection and electronically managed ignition
- Converts the fan drive to a V-rib belt arrangement
Technical Details
- Sync 2 module with two ZF digital Hall-effect sensors
- V-rib crank pulley and trigger disc for parallel-end crankshafts
- V-rib fan pulley, eccentric idler assembly and matching belt
- Recommended sensor voltage: 8V; supported operating range: 5–12V
- Anodised machined-aluminium housing with bronze bush and sealed roller bearing
- Supplied with wiring, terminals and connectors for loom integration
Installation Requirements
The sensor module mounts in the original distributor position and uses the factory distributor gear transferred from the existing unit. Installation involves connecting the sensors to a compatible ECU, setting the crank-sensor air gap and configuring the reference position in the ECU software.
As the module takes the place of the ignition distributor, the engine must use coil-on-plug ignition or an individual coil-and-lead arrangement controlled by the ECU. Professional installation and engine-management configuration are recommended.
Why Replacement Matters
A sequential EFI conversion requires dependable crankshaft and cycle-position data so the ECU can schedule individual ignition and injection events. This combined Adapt Motorsport package provides both signals while adding the crank pulley, fan pulley, idler and V-rib belt components required for the compatible 3.2 installation.
FAQs
- Does the kit include both crank and cycle-reference sensors?
Yes. The Sync 2 body contains two ZF Hall-effect sensors for crank and engine-cycle information. - Can the original distributor continue to control the ignition?
No. The module occupies the distributor mounting position, so ignition must be managed through a suitable ECU and individual coils. - Is this V-rib version suitable for a 2.7 or 3.0 engine console?
No. The manufacturer specifies that the V-rib arrangement requires a 3.2 engine casing and console. - Are electrical connectors supplied?
Yes. The package contains the wiring, connector housings and terminals needed for integration with the engine loom.

This kit is comprised of the following items:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
Adapt Motorsport Sync 2 ignition reference and synchronisation sensor kit for Porsche 911 Carrera 3.2 models from 1984–89. This version includes a 127/133mm air-conditioning crankshaft pulley and 36-1 trigger disc for engines using the larger 3.2 AC pulley diameter.
Fits
- Porsche 911 Carrera 3.2 1984–86
- Porsche 911 Carrera 3.2 G50 1987–89
Visually confirm the crankshaft pulley and air-conditioning drive arrangement fitted to the engine. Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The kit provides a compatible engine control unit with crankshaft speed, crank position and engine-cycle synchronisation signals. One Hall-effect sensor monitors the teeth and missing-tooth reference of the 36-1 crank trigger, while the second reads a single tooth within the distributor-location module.
Because the module is driven at half engine speed, its reference sensor generates one pulse for every two crankshaft revolutions. The ECU can therefore distinguish between the compression and exhaust strokes, providing the position information required for sequential fuel injection and electronically controlled ignition.
Functions
- Measures crankshaft speed and angular position
- Supplies a missing-tooth crank reference from the 36-1 trigger disc
- Generates one engine-cycle synchronisation pulse every 720 degrees
- Allows a compatible ECU to identify the compression stroke
- Supports sequential fuel-injection and ignition strategies
- Fits in the original distributor mounting location
Technical Details
- Sync 2 body assembly with two ZF digital Hall-effect sensors
- 127/133mm AC crankshaft pulley and 36-1 trigger disc
- Pulley designed for parallel-end crankshafts
- Recommended sensor supply: 8V; supported range: 5–12V
- Machined aluminium housing with anodised finish, maintenance-free bronze bush and sealed roller bearing
- Wiring, terminals and connectors for integration with the engine wiring loom
Installation Requirements
The sensor body replaces the original distributor and reuses the factory distributor gear removed from the existing unit. Installation requires connection to a compatible ECU, adjustment of the sensor air gap at the crank trigger and configuration of the reference position within the ECU software.
As the distributor no longer routes the ignition spark, the engine must use coil-on-plug ignition or another individual coil-and-lead arrangement controlled by the ECU. The manufacturer states that this kit is not compatible with Porsche 964 or 993 3.6 engine cases, which require a separate sensor solution.
Why Replacement Matters
A sequential engine-management conversion requires reliable crankshaft and cycle-position information before the ECU can correctly schedule individual injection and ignition events. This kit combines both signals in one distributor-location assembly and includes the larger AC pulley required by 1984-onwards Carrera 3.2 installations.
FAQs
- Does the kit provide crank and synchronisation signals?
Yes. One sensor reads the 36-1 crank trigger, while the second generates an engine-cycle reference once every two crankshaft revolutions. - Can the original distributor ignition remain fitted?
No. The module occupies the distributor location, so ignition events must be controlled by a compatible ECU using coil-on-plug or another per-cylinder coil arrangement. - Is this the correct AC pulley for an early 2.7 or 3.0 engine?
No. This 127/133mm version is intended for 1984-onwards 3.2 engines with the larger air-conditioning pulley diameter. - Does the kit include wiring connectors?
Yes. Wiring, terminals and connectors for connection to the engine wiring loom are included.

- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
Visually confirm the crankshaft pulley and air-conditioning compressor arrangement fitted to the engine. Check fitment for your specific vehicle, model, year and engine before ordering.
What This Product Does
The crank sensor monitors the teeth of the 36-1 trigger disc, enabling a compatible ECU to determine crankshaft speed and position from the pulse sequence and missing-tooth reference. The second Hall-effect sensor is housed in the distributor-location module and reads a single reference tooth at half engine speed.
This reference signal occurs once during each complete four-stroke cycle, allowing the ECU to identify whether the engine is on its compression or exhaust stroke. Combining both signals supplies the position data required for sequential fuel injection and ECU-managed ignition.
Functions
- Measures crankshaft position and rotational speed
- Provides one engine-cycle synchronisation pulse per 720 degrees
- Enables sequential injection and ignition strategies with a suitable ECU
- Installs in the original distributor mounting position
- Provides digital Hall-effect sensor outputs
Technical Details
- Sync 2 module with two ZF digital Hall-effect sensors

- 36-1 crank trigger disc
- Recommended sensor supply voltage: 8V
- Supported sensor operating supply: 5–12V
- Machined aluminium housing with an anodised finish, maintenance-free bronze bush and sealed roller bearing
Kit Contents
- Main dual-sensor body assembly
- Two ZF Hall-effect sensors
- 127/90mm crankshaft pulley and trigger disc
- Wiring, terminals and connectors for connection to the engine wiring loom
Installation Requirements
The assembly occupies the original distributor location and uses the factory distributor gear removed from the existing unit. Installation involves connecting the sensors to a compatible engine control unit, setting the correct sensor gap at the crank trigger and configuring the reference position in the ECU software.
As the original distributor is removed, the engine requires coil-on-plug ignition or another per-cylinder coil and ignition-lead arrangement in which the ECU controls each ignition event.
Why Replacement Matters
Sequential engine management needs reliable information for engine speed, crank position and the current four-stroke cycle. This kit supplies both crank and cycle-reference signals without using the original distributor to route the ignition spark, supporting conversion to compatible electronic fuel-injection and ignition control.
Important Installation Notes
- The 127/90mm pulley is intended for early piston-style air-conditioning compressor installations and is not the correct version for 1984 onwards 3.2 engines.
- On magnesium 2.7 engine cases, a small boss near the crank pulley must be trimmed or die-ground to provide clearance for the trigger disc.
- The system does not fit Porsche 964 or 993 3.6 engine cases; these require the separate 964/993 sensor solution.
- Confirm ECU compatibility, sensor supply voltage, distributor gear suitability and available pulley clearance before installation.
FAQs
- Does the kit generate both crank and cycle-reference signals?
Yes. One sensor reads the 36-1 crank trigger, while the second provides a synchronisation pulse once every two crankshaft revolutions. - Can the standard distributor ignition system remain in use?
No. The sensor module installs in the distributor position, so ignition must be controlled by the ECU using coil-on-plug or another individually controlled per-cylinder arrangement. - Is this pulley suitable for a 1984 onwards Carrera 3.2?
No. Later 3.2 installations use a larger air-conditioning pulley diameter and require the 127/133mm version. - Does installation on a 2.7 magnesium case require modification?
Yes. Adapt Motorsport specifies that a small crankcase boss must be reduced to create trigger-disc clearance.

- Porsche 911 1987-1989 3.2L G50
Check fitment for your specific vehicle, engine casing, distributor gear and engine-management system before ordering.
What This Product Does
The crank-mounted sensor reads the teeth and missing-tooth reference on the 36-1 trigger disc, allowing the ECU to calculate crankshaft position and engine speed. A second sensor within the distributor-location module generates one reference pulse every 720 degrees, identifying the engine cycle so the ECU can distinguish between the compression and exhaust strokes.
Together, these signals provide the engine-position information required by a suitable aftermarket ECU to operate sequential fuel injection and ECU-controlled ignition.
Functions
- Measures crankshaft position and rotational speed.
- Provides a once-per-engine-cycle synchronisation signal.

Kit Contents
- Main two-sensor body assembly.
- Two ZF Hall effect sensors.
- 127mm crank pulley and 36-1 trigger disc.
- Wiring, terminals and connectors for integration with the vehicle wiring loom.
Installation Requirements
The module mounts in the original distributor location and reuses the factory distributor gear. Installation requires wiring to a compatible ECU, adjustment of the sensor air gap and configuration of the reference position within the ECU software.
Because this kit replaces the distributor, the engine must use coil-on-plug ignition or another arrangement with an individually controlled ignition lead for each cylinder. The ECU must control the ignition events.
Why Replacement Matters
A modern sequential engine-management system requires accurate crankshaft speed, crank position and engine-cycle information. This combined trigger and synchronisation arrangement supplies both signals without relying on the original distributor to distribute the ignition spark.
Important Notes
- This kit is not compatible with Porsche 964 or 993 3.6L engine cases; Adapt Motorsport offers a separate sensor solution for those engines.
- On 2.7L magnesium engine cases, a small boss near the crank pulley must be trimmed or die-ground to provide trigger-disc clearance.
- Confirm ECU compatibility, sensor supply voltage, distributor gear suitability and pulley clearance before installation.
FAQs
- Does the kit provide both crank and engine-cycle signals?
Yes. One sensor reads the 36-1 crank trigger while the internal reference sensor produces one pulse every two crankshaft revolutions. - Can the original distributor ignition arrangement be retained?
No. The module occupies the distributor location, so ECU-controlled coil-on-plug or an individual ignition lead and coil arrangement is required. - Does it fit Porsche 964 or 993 3.6L cases?
No. Those engine cases require the separate 964/993 sensor product. - Is modification required on a 2.7L engine?

The Adapt Motorsport Advanced Fuel Rail Kit combines fuel distribution, Bosch pressure regulation and pulse damping for Porsche 911 Carrera 3.2 applications. It is offered in single- and dual-regulator configurations for custom fuel-system installations.
Fits:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
What This Product Does
Opening and closing fuel injectors generate pressure pulses within the fuel circuit. The integrated damper helps control these fluctuations, while the replaceable Bosch module regulates rail pressure. Combining these components within the rail reduces the need to mount separate regulator and damper units, simplifying the number of hoses and connections required.
Functions
- Distributes fuel between the engine injectors
- Controls rail pressure through a replaceable Bosch regulator module
- Helps suppress pressure pulses created by injector operation
- Reduces the number of external fittings and potential leakage points
- Allows the fuel-hose layout to be tailored to the installation
Technical Details
- Available for Carrera 3.2 manifolds
- Supplied with a 3.8-bar regulator.
- Single version pairs one regulator-and-damper rail with one conventional fuel rail
- Dual version uses two rails, each incorporating its own regulator and damper
- Rated regulator flow is 200 lph per module, giving a combined 400 lph with the dual arrangement
- ORB ports use O-ring seals; AN6 JIC unions and end plugs are included, with fasteners and manifold adapters supplied for the Carrera 3.2 option
Why Replacement Matters
This kit is intended for bespoke or upgraded fuel systems where integrated pressure management can make the installation more compact and easier to service. The Bosch modules can be removed independently, allowing a worn regulator to be renewed or the pressure specification to be changed without replacing the complete rail.
Installation Notes
- Bespoke fuel hoses must be made to suit the vehicle and selected configuration
- The dual-regulator layout requires additional hose routing compared with the single version
- Each regulator is limited to 200 lph; a Bosch 044 pump is stated at 275 lph and therefore exceeds the capacity of one regulator
- Pump output, injector requirements and regulator capacity must be considered together when specifying the complete system
FAQs
- Is the pressure regulator serviceable?
Yes. The rail accepts replaceable Bosch regulator modules, so the module can be renewed separately. - How do the two kit layouts differ?
The single arrangement includes one integrated rail and one standard rail. The dual arrangement employs two integrated rails for a combined regulator rating of 400 lph. - Will the original fuel hoses fit?
No. Custom hoses are necessary for installation. - Can a different operating pressure be selected?
Yes. The normal specification is 3.8 bar, with regulator options stated from 3.0 to 4.0 bar.

Port size must be selected to match the engine and any existing cylinder-head modifications.
FAQs
- Which port size is required for a standard 964 engine? The manufacturer specifies the 41.5mm version for standard Porsche 964 intake ports.
- Which version suits a standard 993 engine? The 43.5mm option is specified for standard Porsche 993 engines with either VRAM or non-VRAM intake systems.
- Which injectors are compatible? The kit accepts Bosch injectors with 14mm O-ring fittings. Its marked posts can be adapted for long, medium or short injector bodies.
- Are the intake manifolds supplied? No. Manifolds, rubber joiners, injectors and hose clamps must be sourced separately.

What This Product Does
The six adapters provide the interface required between the earlier two-bolt cylinder heads and a 996 GT3 intake manifold. Each adapter is machined to the selected cylinder-head port diameter and tapers towards the manifold's 48mm bore.
The compact adapter height helps retain a low overall intake assembly, reducing potential interference between the idle-air control components, intake boot and engine-bay insulation. Injector positioning corresponds with the original CIS injector relief in the intake port, directing the fuel spray into the port when used with a compatible EFI installation.
Kit Contents

Why Replacement Matters
This kit is intended for planned EFI and intake-manifold conversions rather than replacement of a standard component. Correct port selection, injector sizing, fuel-system specification and engine-management calibration are required for a complete installation.
FAQs
- Does the kit fit both available port sizes?
Select either the 40mm or 42mm version to match the cylinder-head intake ports. - Are fuel injectors supplied?
No. The adapters accept Bosch 14mm O-ring injectors, but the injectors must be selected separately. - Is the 996 GT3 manifold included?
No. The intake manifolds, rubber joiners and associated hose clamps are not part of the adapter kit. - Can different injector lengths be used?
The marked fuel-rail spacers can be cut to accommodate long, medium or short injector formats as required by the installation.
