A/C Solutions Porsche 911 3.2 Carrera Complete Conversion Kit

Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade of the A/C system in the 1984-1989 911 3.2 Carrera to R134a using a new Denso compressor, CSF parallel flow condenser, R134a expansion valve, all new R134a lines (inside and out), and all the necessary supporting brackets. This upgrade will result in colder A/C vent temperatures, less strain on the engine, and a more efficient and durable A/C system.

Product Details

Design & Engineering

Designed and engineered specifically for the air-cooled Porsche enthusiast, this complete A/C conversion kit modernizes the 1984–1989 Porsche 911 3.2 Carrera by replacing the outdated R12-based system with a fully updated R134a setup. This is a complete kit, featuring a brand-new Denso compressor, high-performance CSF parallel-flow condenser, R134a-specific expansion valve, all-new R134a lines (interior and exterior), and precision-engineered mounting brackets for a streamlined installation. Each component has been carefully selected to work together as a plug-and-play solution, eliminating the guesswork and hassle of piecing together an upgrade from various aftermarket parts.

The benefits of this system go far beyond simply restoring your A/C System. The advanced CSF parallel-flow condenser dramatically improves refrigerant efficiency, while the new Denso compressor reduces parasitic drag on the engine, delivering both colder vent temperatures and smoother performance. With every line, valve, and bracket replaced, owners can count on improved reliability, reduced strain on aging components, and a system that performs more consistently in modern driving conditions—even in hot climates or heavy traffic. The result is a significantly more efficient and durable A/C setup that enhances comfort, preserves originality, and improves the driving experience for classic 911 owners.

What if my 911 didn't come factory with A/C?

Our products are designed to support factory A/C models; however, to fit them into non-A/C applications you will need to obtain a factory HVAC wiring harness, factory compressor manifolds, aluminum engine accessory bracket, evaporator, and factory HVAC box ("smugglers box") with sensors, control module, thermostat, etc. Additionally, we recommend replacing your OEM hardware with our A/C bracket and hardware kit.

⚠ Fitment Notes

• Compatible with LHD models with factory A/C only.
• Not compatible for models with rear wiper system.
• The A/C compressor does not come with manifolds - you will need to reuse your originals.
