Hi all,
I have a MPFI Turbo EA-82 I am rebuilding for use on a rather largish hovercraft I have under construction. I plan to use the Megasquirt and Spark Fuel Injection/Ignition controller to run it but I'm concerned about trying to use a turbo on an engine that will have water spray around it constantly and how to keep water from getting sucked into the turbo. In studying the Soob factory manuals I'm not so sure a turbo is runnable (if that's a real word) without the original factory brain box anyway because of the RPM kickdown controls,etc. on the turbo that there is no functionality for on the Megasquirt. In my research I've found that there are three different pistons in the EA-82, aspirated(carb) MPFI and MPFI + Turbo. The tops of the turbo pistons (which I have) are dished out pretty significantly. As the bore size is the same on all the EA-82's is it possible to convert a MPFI+Turbo to a MPFI only by just replacing the pistons and eliminating all the extra "junk" associated with the turbo? Has anyone in the forum done this conversion to an engine that they were going to use ouside of the car- say, on a light airplane or gyrocopter? Or, has anyone come up with a way to run the turbo without the factory brain?
