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,

Crafted from high-grade aircraft aluminum, our Porsche G-Model to 964 Billet Intake Runner delivers superior performance enhancements. Available in various cylinder head port diameters ranging from 34mm to 42.5mm, with options for standard injector sizes. 

Compatibility and Customization:
Tailored specifically to fit Porsche 2.7-3.2L engines, this intake runner enables seamless mounting of a Porsche 964/993 type intake. Unlike the 964/993's 3-bolt attachment, our design utilizes a 2-bolt M8 attachment for cylinder head placement.

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.

Porsche 911 SC - 1978 to 1983
Porsche 911 3.2 Carrera - 1984 to 1989

These adapters are used to modify the 2.7ltr / 3.0ltr / 3.2ltr Porsche 911 2 bolt cylinder head engines to the later 964 / 993 3.6ltr intake manifolds when converting to EFI.  

CNC machined on a 5 axis machine to our exacting tolerances and finish and anodised dark grey these are custom machined to match your port diameter and tapered to fit up to the 42mm inlet manifold port size.

The short adapor height maintains the overall height of the intake set, reducing the interference between the idle air control, the intake boot and the top of the engine bay insulation.  The factory plastic 3 bolt 964 stacks are too tall, and adding an adapter spacer would make the manifolds not fit at all.

This design permits the use of the standard 964 fuel injectors and fuel rails so positions the injector over the same relief in the intake port for the original CIS injector, ensuring proper atomisation of the injector spray into the intake port.

Key Features:
Precision machined from high grade aluminium
Anodized finish
Fits all Bosch 14mm O-ring fuel injectors
Fuel rail spacers are marked for easy cutting to suit long, medium or short injector types.

Oil backflow prevention kit. 

Sold as a complete kit. 1 necessary per car.

This oil backflow kit incorporates a check valve between the oil tank and engine which prevents smoking on start up for 911 and 930 models from 1973-89.

The issue is due to the oil tank sitting higher than the engine oil pump. Gravity creates a positive pressure on the pump and slowly fills the engine case with time. Once the car is started, the cars smokes heavily

Our complete kit includes a model specific check valve with upgraded suction hoses and stainless-steel clamps ready for installation.

Why do you need this system and what is a crankshaft position sensor? 

When converting classic Porsches to modern electronic fuel injection, the engine control unit (ECU) needs to know exactly where the crankshaft and camshaft is in its 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. A sensor is pointed at the crankshaft pulley or flywheel 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.  

The 3.2 Carrera / 964 / 993 already have a sensor on the flywheel to measure crankshaft position so these engines only require one senor for camshaft positioning. This sensor is installed in the body our module, and measures a single tooth at the top of the drive shaft.  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 1 Sensor Kit Includes:

• Main body assembly
• ZF Hall effect sensors, single tooth for engine cycle sensing x 1
• Wiring and connectors, with pins and connectors for connecting to your wiring loom.

For use when you already have some other crankshaft position sensing either on the flywheel or pulley and just need to add an engine cycle/sync sensor to complete your sequential system.

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  964, 993 and with the turbo distributor gears.
