The EP-3M-6A is an electronic distributor for the Holden 186 and 202 inline six-cylinder engines -- the six-cylinder powerplants that were the standard engine in the classic Kingswood, Monaro (six-cylinder versions), and Torana across the golden era of Australian motoring from the early 1970s through the mid-1980s. The 202 cubic inch (3.3L) red motor became Australia's most-loved six-cylinder engine, known for its strong torque output and exceptional durability.

Converting the Holden 186/202 from original points ignition to electronic ignition is one of the most popular and recommended upgrades in the Australian classic car community. The EP-3M-6A replaces contact-breaker points with a maintenance-free magnetic pickup, eliminating the regular dwell angle adjustment and points replacement that has always been a feature of Holden six ownership. This conversion improves cold-start reliability, idle quality, and overall ignition consistency.

EP exports the EP-3M-6A to Australian and New Zealand aftermarket suppliers serving the very active classic Holden six-cylinder enthusiast and daily driver community.

Installation guide

Disconnect battery. The Holden 186/202 distributor is located at the rear of the engine on the driver's side. Mark rotor position and housing alignment for the 186/202 firing order (1-5-3-6-2-4). Remove the points-type or existing electronic distributor. Install EP-3M-6A in same orientation. Reconnect vacuum advance hose. For points-to-electronic conversion: remove the ballast resistor from the ignition circuit and connect the electronic ignition module to a direct 12V feed. Set timing with a timing light to factory specification (typically 8-10 degrees BTDC for the 202).

Frequently asked questions

What are the symptoms of a failing GM EFI distributor?
Common failure symptoms for GM EFI distributors of this era include intermittent no-start conditions, engine stalling at operating temperature, erratic idle quality, loss of power under acceleration, and check engine codes related to the distributor reference signal or cam position sensor. The Vortec-era distributors (1996-2002) are particularly known for plastic housing cracking or warping from heat cycling, which allows oil or coolant contamination of the optical or magnetic pickup sensor inside the housing. The LT1 Optispark distributors (1992-1994) are known for moisture infiltration that degrades the optical sensor window, typically producing a characteristic hard cold-start condition that improves as the engine warms up.
Does the EP-3M-6A ship with the cap, rotor, and all necessary sensors?
Yes. The EP-3M-6A ships as a complete plug-and-play assembly including the distributor body, distributor cap, rotor, and all internal sensors required for operation in the listed applications. For Optispark LT1 units, the optical sensor assembly is included as part of the complete distributor. For standard EFI units, the magnetic pickup and cam position reference sensor are integrated into the assembly. No additional ignition components are required beyond the standard ignition module and coil already present on your vehicle.
Does the Holden 186 and 202 use the same distributor?
Yes. The Holden 186 CID (3.0L) and 202 CID (3.3L) six-cylinder engines share the same basic block architecture and distributor drive configuration. The EP-3M-6A fits both the 186 and 202 across HQ, HJ, HX, HZ Kingswood, Monaro six-cylinder, Torana, Statesman, and WB applications. The firing order and timing specifications differ slightly between the two displacements -- consult the factory specifications for your specific engine.
Do I need to reset the timing after installing this distributor?
For most GM EFI applications of this era, the distributor does not require timing adjustment after replacement if the engine is set to top dead center (TDC) before the old distributor is removed and the new unit is installed in the same position. Most 1987-1995 GM TBI and EFI applications use a computer-controlled timing advance that does not require a timing light for replacement -- align the distributor housing marks and the rotor to the same position as the original unit. For 1992-1994 LT1 Optispark applications, the base timing is not adjustable in the field; the Optispark provides a crankshaft-referenced timing signal and the PCM controls all timing advance. Consult the factory service manual for your specific vehicle year and engine for the correct installation procedure.
How do I order the EP-3M-6A for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
