Spica Pump Rebuilds
We replace all the plungers and barrels on all our rebuilt pumps to prevent gasoline from seeping into the engine oil. Our pumps include upgrades to correct several original pump design defects. After re-assembly each pump is installed on our test bench and run for more than 8 hours that simulates actual engine operating conditions. Fuel calibration is set to less than 1% differential between cylinders at selected speeds and load points. This results in more Power, fuel mileage and reduced emissions.
HP Pumps Note: There will be an extra charge for failed fuelcut-off solenoids on pumps received for rebuilding (De-cels) Our rebuilt pumps feature the fruits of knowledge gained over our years of rebuilding them. We have identified their weaknesses and have developed alternatives and guidelines to make them last longer. Each of our pumps have these upgrades installed. Our booklet "Manual for Alfa Romeo SPICA Fuel Injection" is available for $30 and details all the changes that are made, as well as just about everything you'd care to know about these pumps. The diagnostic flow chart has proved to be a highly useful tool among owners. | ||

Each of our pumps are bench tested on our custom built flow bench for as long as it takes to get the flow from each injector balanced to within 1%, at low, medium, and high pump speeds. | |
High Performance (HP) Pumps | ||

HP pumps are a very popular option that exists for owners of modified Alfa motors. The HP pump matches the fuel metering characteristics to the breathing mods done to the engine. You wouldn't throw larger cams in the motor without increasing jet size, would you? Without modifying the pump's fuel distribution curve you won't maximize the potential of your improvements. The heart of the HP pump is the re-profiled 3-D cam. We've developed several styles of the 3-D cam to deliver correct fuel mixtures at all engine speeds. It is necessary to specify the engine mods and power expectations on custom orders. Note that the 40mm throttle bodies are available for all SPICA cars and particularly those with modified engines. | |
