In addition to the sizeable performance improvement over its spiritual ancestor, the fabled 911 RS, the 930/911 turbo could have also easily exceeded its legendary power/throttle response enabled tossability had economics and technology enabled fitting a quality engine management system. PWR now regulary closes that gap with our CIS to EFI conversion system packaged with a purpose built engine and optimized chassis in the form of our PWR 930 Club Sport.

Even if you can resist the urge to go with this configuration, you can still expect the following when replacing your current CIS system with EFI in your car.

  Vastly improved throttle response.   MAP sensor now inches away from throttle blade instead of 6 feet on CIS system, no air impedance from sensor plate and 3D ignition timing up to 15 degrees advanced over stock at some intervals in advance curve.

  More accurate fuel delivery/optimized ignition timing.   Permits higher static compression ratios (up 8.2/1) and boost (1 bar safely on pump gas) on basically stock engines.

Far more   scalable to future improvements   (look at our 623hp 3.5 litre engine) that CIS which limits engine mods to about 450hp safely while retaining passable driveability.

Whether replacing your aging CIS system with the latest technology or specifically looking for improved power/driveability/efficiency, this is the   most cost effective EFI conversion on the market.  

An increasing problem with CIS system component replacements,   all components are OEM and readily available.  

  Vastly improved access to your engine compartment for servicing    (Look at our shop motor install in the 1977 930.)

Unlike CIS,   tuneable to your exact engine configuration and with greater accuracy.   Try CO readings of .2 percent compared to the standard 3.5% required with performance oriented CIS systems proving still only nominal fuel flow and protection at high rpm/boost levels.

  Far greater reliability with less component failure.   For example, though CIS injectors popoff at relatively low pressure (1-2 bar), they require system pressure as high as 7.2 bar (100+psi) to operate and residual pressure remaining in the system to ensure your engine will even start. Our CIS-to-EFI conversion replaces all of these components (fuel pump check valves, residual pressure valves, fuel accumulators, etc) with one, a readily accessible fuel pressure regulator. All PWR-EFI components are built to modern EPA emission's life cycle requirements.

  Consolidates all engine control functions into one electronic control unit.   Adds boost control, hard/soft shift points, infinite ignition/fule mapping while eliminating your former cold start circuit, expensive ignition control system (CD Box), ignition cutoff delay, lambda control unit, etc.
