Replaces Bosch 0280160262, 0280160232, 0280160215, Porsche 92811019802, 92811019801, 92811019800, 92811019826 (2.5 Bar no vacuum line connected)

Most of these regulators are original and now nearly 40 years old so they are prone to leak or fail causing all sorts of running and tuning issues.  They are easy to replace, albeit a little bit fiddly being at the front of the manifold for the 3.2ltr engine. To suit the lower operating fuel pressure of the 3.2 Motronic, we use an adjustable fuel pressure regulator.  This simple and elegant design uses steel O-Ring boss sealing adapters to the manifold. 

Easily replaceable fuel pressure regulator.
Spare outlet for fuel pressure gauge or sensor.
The adjustable fuel pressure regulator has been tested with Bosch 044 fuel pumps, but the upper limit of fuel flow rate has not been tested.

Kit Includes:

• Porsche 911 3.2 Carrera / early 928 (non CIS) OEM fitting kit - SPA adjustable fuel pressure regulator
• Fuel pressure regulator body x 1
• 2.0 to 5.0 adjustable fuel pressure regulator instead of fixed regulator x 1
• Adapter fittings to fit OEM hose and fuel rail ends x 2
• Hose Tail fitting to fit factory return line x 1
• ORB Plug x 1

This kit must use the adjustable fuel pressure regulator as Bosch does not produce a standard 2.5bar pressure regulator in this form.  

Please Note
Other fittings and options such as fuel pressure sensors, or fuel pressure gauges available upon request.
We have also developed fuel pressure dampers for the 3.2 and 928 engines, check out our site for the product details.
The fuel pressure regulator needs to be adjusted and set on the car after installation to ensure the operating conditions meet the factory specifications.  A fuel pressure gauge and fittings to adapt to the factory fuel rails is required to be able to complete this procedure.  The regulators are not shipped pre-set to the 2.5bar operating pressure.

We can also provide a solution for early 944 replacing Porsche part number 94411019801, Bosch part number 0280160214,

Adjustable fuel pressure regulator with JIC / AN fittings. Porsche 911 EFI upgrade



Fits:
Porsche 911  - 1974 to 1983 (CIS to EFI upgrade)

This is the Motorsport/Custom version of our fuel pressure regulator that uses AN6 JIC fittings and plugs to suit aftermarket fuel lines and fuel rail configurations when converting from CIS to EFI, or removing the later model fuel injection systems for an alternative custom setup.

Our adjustable fuel pressure regulator uses the latest Bosch regulators and is adjustable from 2.0 to 5.0 Bar pressures. This simple and elegant design uses O-Ring boss sealing adapters to the manifold with multiple options for hose connections.  Ultimate hose layout flexibility is achieved through multiple port orientations and options so this allows for standard 3.2, 964, or 993 fuel hose configurations, or, for dead head configurations where there is a single feed line to each fuel rail and no return line from the rail, only this regulator.  

Easy to replace regulator with Bosch OEM reliability

3 outlet ports for flexible hose, fitting, gauge, sensor port options - now or for the future

This kit is perfect for any EFI conversion on any of the air cooled 6 cylinder engines.  These can be combined with our fuel rails that fit to either our 2 bolt adapters, or the 964/993 intake stacks

The Bosch regulator is rated to a maximum fuel flow of 200lpm.  The adjustable pressure regulator flows more, but we have not yet measured its upper limits, but it has been proven to work with a Bosch 044 fuel pump.

Kit Includes:

• Fuel pressure regulator body x 1
• 2.0 to 5.0 adjustable fuel pressure regulator instead of fixed regulator x 1
• AN6 JIC fittings x 4

Dual crankshaft and camshaft position sensor for electronic fuel injection upgrade. Porsche 911 1974 to 1983
Dual sensor kit with pulley is the complete engine position monitoring kit

Fits:
Porsche 911 / 911S - 1974 to 1977
Porsche 911 3.0ltr Carrera - 1976 to 1977
Porsche 911 SC - 1978 to 1983
Porsche 911 turbo - 1975 to 1989
For cars with CIS / K-Jetronic fuel injection

The dual sensor unit, no pulley is for people who might be upgrading from another crank sensor kit, and have a trigger installed. So long as the trigger wheel diameter is between 127mm and 132mm in diameter, then our kit can most likely be used with the existing trigger wheel.

Dual sensor 
Trigger every 720 degrees (compression stroke)
36 tooth trigger wheel

Dual sensor – This unit has the same sensor as the in the body as the single sensor, but a second sensor that points at the trigger disc mounted to the Adapt Motorsport crank pulley. As standard, this is a 36-1 pulley, meaning that it has 36 teeth, minus 1 missing tooth. This allows the ECU to know what the crankshaft position is at all times and in combination with the internal sensor, whether it is on the compression or exhaust stroke in its 720 degree cycle. This system provides a complete engine position sensing kit. If you have an existing 36t trigger disc, it is possible to use our sensor kit on this, provided that the teeth are designed for a hall sensor, and not a magnetic sensor, and the outside diameter of the teeth is between 127 and 

130mm. Please contact us for clarification

Why do you need this system and what are crankshaft/camshaft position sensors? 

When converting classic Porsches to modern electronic fuel injection, the engine control unit (ECU) needs to know exactly where the crankshaft and camshafts are in there 4 stroke cycle and how fast they are spinning.  This allows the ECU to correctly time each spark and fuel injector opening time and duration.  The first sensor is pointed at the crankshaft pulley and measures a pulse for every tooth.  There is one missing tooth and from this the ECU can work out what the crankshaft position is relative to this missing tooth.  The time between pulses gives the engine speed and rate of change.  

But there is a problem, the engine spins two complete revolutions to complete its 4 stroke cycle.  So whilst with this one sensor, the ECU knows where it is relative to top dead centre (TDC), it does not know if it is on the compression or exhaust stroke.  This is where the second reference sensor comes in.  This sensor is installed in the body our module, and measures a single tooth.  As this is installed in the distributor hole, this is geared to run at half engine speed, so will produce a pulse once every 720 degrees.  With these two sensors, the ECU knows the exact position the engine is in its 4 stroke cycle.  And now, we can run accurate sequential injection and ignition.

Our kit uses high speed digital hall effect sensors for a digital output to the engine control unit, these are best run at 8V, most modern ECU's have an 8V output dedicated for crankshaft sensors.

Machined aluminium housing and anodised finish, complete with maintenance free bronze bush and sealed for life roller bearing.  These sensors are quite adjustable so are often able to be used with existing crank pully and trigger wheel setups from other quality vendors.

Sync 2 Kit Includes:
Main body assembly
ZF Hall effect sensors x 2
Wiring and connectors, with pins and connectors for connecting to your wiring loom.

For use with other crank trigger systems.
(We can not guarantee that that this system will fit every crank/trigger system, however it can be easily modified to suit most systems)

This replacement kit fits to the OEM distributor location using your own factory distributor gear. Simply remove the factory distributor gear from your install the gear, wire to your ECU, fine tune the sensor air gap to the crank trigger disc, setup the reference position in the ECU and you have all the sensing you need for the latest sequential fuel and ignition systems.  This kit works on the 2.7lre, 3.0ltr and with the turbo distributor gears.

Please Note
2.7 engines may need to trim some of the crank case near the crank pulley to prevent interference.

This kit is a modern update to the 911 3.2 ignition system and brings the management of the car into the digital age to allow greater control over ignition and fueling.

The kit replaces your restrictive old fashioned air flow meter (barn door) with a modern map sensor managed by intake pressures.

The kit gives many driving benefits, better/smoother power delivery, better throttle response, eliminates lots of the low-down idle problems as it now uses a throttle position sensor and delivers more torque and BHP.

The kit is delivered ready to use with a PPT ignition map for the 3.2 standard engine management; however, the kit can be mapped for different cams and engine capacity increase.

Our latest kit now comes with an upgraded ECU and can run a wide band sensor (oxygen sensor).
Our kits include this capability but the sensor needs to be ordered separately.

While developing the upgraded ECU we have also changed our intake pipe; this now works with the factory airbox, gives a stock appearance in the engine bay and houses the map sensor and air temp sensor out of sight.

Kits includes:
• Delta 700 ECU
• 2 x Direct plug-in wiring looms
• Map Sensor and air temp sensor
• Air intake pipe, gasket, and bolts
• 6 Bosch injectors
• Vacuum pipe and T connector
• Throttle Position Sensor (TPS) and adaptor
• Support and service by PIE Performance
• Can Bus data connection tool

All our kits are 100% reversible, with no need to drill or alter components, we utilise what already exists

Patented technology that helps to increase air flow dramatically thus minimising air flow separation and reduces turbulence, resulting in higher volumetric efficiency.

This pristine technology with Knife-edged butterflies has improved inlet airflow and performance significantly. With the individual Throttle blades very close to the inlet valves, the engine and Throttle response are vastly improved. Along with this, we have also found an impressive increase in Horsepower, Torque, Driveability, and an incredible mechanical soundtrack.

Throttle Bodies come fully assembled and ready to bolt directly to the Cylinder Heads, with the following parts included:

• Anodised Aerospace Grade 6082/T6 Billet Aluminium "Shaft-less" Individual Throttle Bodies.
• Anodised Aluminium Inlets/Extensions suitable for flatdeck & ducktail models.
• Aluminium Ram Pipes & Assembly Tool.
• Throttle Position Sensor (TPS).
• Billet Aluminium Fuel Rails, Including PICO 377cc Fuel Injectors.
• Thermal Insulation Gaskets.
• Throttle Linkage System which connects directly to the existing OEM cable pick-ups.

Notes
Tested to 10,000 RPM

Increasing the performance of an engine via the crankshaft does not make sense at first glance, but it is worth taking a closer look. 

The mechanical efficiency of an engine, which, together with the thermodynamic efficiency and the volumetric efficiency, determines the rated output of an engine, depends fundamentally on the diameter of the crankshaft bearings and the friction in the bearings. 

Of course, the diameter cannot be easily changed, but the friction can, which in turn depends on the bending loads and the resulting vibrations of the crankshaft. This is exactly why the use of top-quality titanium connecting rods is of little use if the resulting significantly reduced rotating masses at the connecting rod foot are not also taken into account on the counterweight side of the crankshaft. 

Because only a perfectly designed crankshaft, calculated for the connecting rod weights, actually brings with it less bearing friction due to eliminated vibrations, and thus an increase in performance. Furthermore, this crankshaft is speed-resistant up to 11,000 rpm and tested in continuous operation up to 10,000 rpm. A pleasant side effect is of course a reduced load on the crankcase and less wear. 

This crankshaft is designed utilising the latest calculation methods using CAD and FE methods (finite elements) and is designed for operation with titanium connecting rods only.

If you want to run this crankshaft with steel connecting rods, use crankshaft part number 90110201100/1. Failure to comply with the mass balance will sooner or later lead to the crankshaft breaking at maximum speeds. 

Furthermore, this crankshaft is an authentic replacement for every standard crankshaft of the 911 from 1965 to 1971, i.e. every 2.0ltr and 2.2ltr engine. 

You can easily swap out any 2.0ltr or 2.2ltr 911T crankshaft that doesn't have factory counterweights for this crankshaft with counterweights.
