- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
Adapt Motorsport Sync 2 ignition reference and synchronisation sensor kit for early Porsche 911 2.7 and 3.0 engines equipped with a piston-style air-conditioning compressor. It combines a dual-sensor module with a 127/90mm crankshaft pulley and 36-1 trigger disc.
Fits:
- 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
- 127/90mm air-conditioning crankshaft pulley for parallel-end crankshafts
- 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.
