Starter Motors
Bypass your expensive ignition switch and install a hot start relay that will lead the current directly to the starter.
We have a 6 or 12 volt version and it works in any classic.
Fits:
Porsche 911 / 924 / 928 / 914 / 944 / 968 / 356
This relay can be placed near the starter motor and is used to limit the starting current and no longer allow it to be switched via the ignition switch.

WOSP high torque, lightweight, gear reduction starter motors are manufactured in the UK. Unlike alternatives in the market place these are built using only 100% OE parts and units, therefore can't be rivalled on quality.
In most cases WOSP starters are designed with an indexable 360 degree mounting plate meaning no obstruction should get in your way when installing.
The main advantages over the original starter is the durability along with a weight and space saving. The improved performance means they also reduce loads on the vehicle's battery and electrical system.
Direct replacements to the original item, plug & play / fit & forget.
All units come with instillation instructions and a 12 month warranty.

Powerlite offer a wide range of high torque gear reduction starter motors. The lightweight units offer increased cranking speeds and considerably more cranking power than original units, whilst drawing less current from the battery. The units are ideal for road competition applications, especially where engines have been tuned and adverse conditions require extra performance from the starter motor. All Powerlite starters are direct replacement for original units and require no modifications to the vehicle on which they are installed. The compact lightweight units are often easier to install than the original unit and units are modified where necessary to aid fitment.

Starter Motors – Reliable Engine Starting Power for Porsche Vehicles
Starter motors are essential components that provide the torque needed to start your Porsche’s engine. When you turn the key or press the start button, the starter motor engages the flywheel to crank the engine and initiate combustion. A reliable starter ensures smooth, instant starts every time — whether your Porsche is cold, hot, or under performance load.
At Design911, we stock a wide range of genuine and high-quality starter motors for Porsche models including, amongst others the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each unit is engineered to meet the precise power and durability standards required by Porsche’s high-performance engines, ensuring long-term reliability and optimal starting performance.
What Do Starter Motors Do?
Starter motors convert electrical energy from the battery
into mechanical energy to crank the engine. Their key functions include:
- Engaging
the engine flywheel to initiate combustion.
- Delivering
consistent cranking power under all temperature conditions.
- Supporting
quick, smooth starts without hesitation.
- Ensuring reliable operation during repeated starts in traffic or performance use.
A high-quality starter motor ensures dependable ignition response and prevents starting delays, especially in performance-tuned or older Porsche models.
Why Do Starter Motors Fail?
Starter motors operate under intense electrical and
mechanical load, which can lead to wear over time. Common causes of failure
include:
- Worn
brushes or bearings leading to slow or intermittent operation.
- Electrical
faults such as bad solenoids or worn armatures.
- Heat
and vibration degrading internal components.
- Corroded
terminals or poor grounding reducing current flow.
- Age-related mechanical fatigue causing engagement failure.
Typical symptoms include clicking sounds when starting, slow cranking, complete no-start condition, or intermittent starting performance.
Why Replace a Failing Starter Motor?
A worn or failing starter can leave your Porsche unable to start or damage other electrical components. Replacing it ensures reliable ignition performance, consistent power delivery, and peace of mind.
Benefits of replacement include:
- Instant, reliable engine starting.
- Smooth and quiet operation.
- Reduced electrical strain on the battery and alternator.
- Manufacturer-quality performance and long-term durability.
All starter motors in our range feature precision-wound coils, high-strength gears, and heat-resistant housings for dependable operation and extended service life in demanding Porsche applications.
