 WOSP 200 Series 105 amp Alternator

The WOSP 200 Series Alternators are designed as direct replacements for OEM alternators, making them ideal for classic Porsche restorations, standard road use, or motorsport applications where a smaller, lower-output alternator is preferred.

Unlike the modern 300 Series units, the 200 Series uses traditional round-wire stator technology. This makes them faithful to original designs while still benefitting from WOSP’s reputation for high-quality engineering and reliability.

Key Features of the 200 Series 

• Round-Wire Stator Design – based on traditional alternator construction, offering reliable charging performance.
  
• Direct OEM Replacement – plug-and-play compatibility with factory alternators.
  
• Lower Output Race Alternators – compact, lightweight designs available for motorsport or specialist builds.
  
• Durable Construction – built to WOSP’s exacting standards to withstand heat, vibration, and long-term use.
• Easy Fitment – engineered for straightforward installation without modification.

Why Choose a 200 Series Alternator?

• OEM Accuracy – ideal for those seeking authenticity in restorations.
  
• Cost-Effective Reliability – a direct replacement for worn or failing factory units.
  
• Motorsport Ready – smaller/lower output versions reduce parasitic loss, improving efficiency in lightweight race applications.
  
• Proven Technology – traditional design trusted for decades, refined by WOSP for modern standards.

Common Signs Your Alternator Needs Replacing

• Battery Warning Light on dashboard
  
• Dim or Flickering Lights at idle or under load
  
• Flat Battery or difficulty starting
  
• Electrical Failures when multiple systems are in use
  

Unusual Noises from the alternator bearings

If you experience these symptoms, replacing your alternator with a WOSP 200 Series LMA036 ensures dependable charging and reliable performance.

Upgrade your classic vehicle’s charging system without compromising its period-correct appearance, with Wosp’s Dynator – a high-performance 6 or 12V alternator cleverly disguised as a traditional dynamo or generator. 

Designed and manufactured in-house in the United Kingdom from billet, these units deliver approximately double the output of the original dynamo they replace, while offering greater efficiency and weighing just 60% (approx.) as much.

Fits:
Porsche 912 1965-68
Porsche 356 B 1.6L 1960-63
Porsche 356 C 1.6L 1964-65

Fitment Information: 
The diameter of this unit is slightly larger than that of the original dynamo (90mm), meaning the cradle it mounts on will need to be machined to accommodate the increased size. 

These internally regulated units are direct replacements for the original dynamo. You simply have to bypass your regulator box or replace it with one of our dummy bulkhead mounted regulator boxes to eliminate any wiring modifications.
