Electric Air Conditioning Kit Compressor and Condenser Half Kit for Porsche 911


The Electrocooler 'half system' allows existing AC cars to use our electric compressor and modern condenser with the existing evaporator blower mounted in the smuggler's box. 

Fits Porsche 911 models 1965 to 1989 with factory/dealer fitted AC. 

If your factory or dealer fitted evaporator / blower is in good condition but your compressor and hoses are tired, this is the kit for you.  The kit contains compressor and mounts for fitment ahead of the fuel tank.  The new condenser can be fitted in place of the washer bottle on 74 onwards cars.  Early cars can mount the condenser in the rear wheel well.  Complete new set of hoses and all wiring are included.

This is a 'half system' AC system to be used with the factory evaporator/blower.

  • All Electric. All modern components
  • Weighs around 22lbs (10 kg)
  • Retains factory evaporator / blower
  • Fits in front luggage bay
  • Lightweight narrow hose set weighing under 4lbs (1.5kg)
  • Easy Install. Non-damaging bolt-in installation
  • Clutter Free. Uses existing air vents to deliver cool air
  • Simple to Use. Controlled by a single ‘smart button’
  • Energy Efficient. Uses less than 1 HP of engine power
  • Kits available to fit 911s from 1965 to 1989 (please check for fitment before purchase)

High power blower motor and evaporator assembly for air conditioning. 

Fits:
Porsche 911- 1965 to 1989

Our new, Gen 2 fresh air blower assembly for Porsche 911 models is designed to replace the ancient and noisy original fresh air blower.
As with all Classic Retrofit products, it fits straight into the car without modification, using the original electrical plug and Bowden cable work.
It is true plug and play.

Internally, the blower unit uses a modern double-cage fan which can move more air than the original. The real game changer is that it incorporates a modern parallel flow evaporator. 

This allows a 911 with our A/C to get rid of the clunky separate A/C blower in the smuggler's box (LHD) or behind the passenger footboard (RHD). Two blowers are integrated into one modern unit, saving weight and space.

You can pair this blower with a traditional A/C system or if you want to join the electric A/C revolution, try our complete electric kit.

  • Replaces original fresh air blower
  • Double cage fan
  • Parallel flow evaporator
  • Recirculation function
  • Plug and play electrical connector and Bowden cable
  • Weighs 5.0 kg

Ignition Starter Unit CDI 6 PIN.
(Bosch Ref 0227300004)

Classic Retrofit replacement CDI+ ignition offers you bespoke modern electronics in a standard looking package. The CDI+ unit requires no modifications to the original wiring harness or vehicle metalwork and is 'plug and play'.

The CDI+ is a direct replacement for the 3 pin and 6 pin Bosch units fitted to Porsche 911's between 1969 and 1983 (and turbo models to ~1988). All CDI+ units have a 48 MHz microprocessor onboard to control ignition timing.

Advanced Unit:
The advanced unit allows the adjustment/tuning of the ignition advance curve and other features by plugging in a laptop. This can be achieved by 'overlaying' a curve on top of the distributor weights/springs curve or by locking the distributor and replacing the curve completely. Either way, you can unlock the true potential of your engine by adjusting fuelling and having the ignition curve to match.

The CDI+ has all the features of the basic unit but allow more flexibility in adjustment:
-Fully programmable ignition advance curve.
-Hard RPM limiter with adjustable ignition cut schemes
-Soft RPM limiter with adjustable ignition retard
-Launch RPM limiter
-Double spark at all RPMs
-Max RPM tell tale
-Shift Light output
-Clutch pedal input
-Tacho calibration
-Upgradeable through firmware updates

Fits:
Porsche 911 1978-83
Porsche 930 3.3L 1978-89
