The EA-82 is the power plant called for in the hovercraft plans, the original power plant was an air cooled VW flat four. It's also the engine I aquired to execute the hovercraft build. Not being all that Suburu saavy at the time I might have opted for the other engine. While some will argue that th EA-82T is the worst engine Subaru ever made, millions of cars ran on them. IMHO it's like anything else. A company can manufacture 100 million widgets and all you will ever hear about is the 100,000 that broke. Thats a 0.001% failure rate....

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?

Great forum. There are clearly many knowledgable Soobies here! Does anyone know the wiring signal connections for the EA82 Turbo EFI distributor with the optical inturruptor disk? For some background- I'm putting the engine on a rather largish hovercraft I'm constructing. For ignition control ans EFI control I am using the latest version of the Megasquirt DIY-EFI ( http://www.bgsoflex.com/megasquirt.html ) system that now controls both fuel injection and ignition. To interface the disro to control the ignition, I need to know firstly what color wires hook to power and which color wires are the ignition timing and crank angle strobe signals. And last, but probably not least, There are 4 slots on the the inturruptor plate obviously for ignition timing, and lots and lots of holes for the crank angle timing. If anyone knows how many holes are in the plate for the crank angle sensing it'll save me a gob of time counting them. I'm sure it is a number divisable by 360. The opto module is stamped RSB-06 and 7617 which is probably the manufacture date. Thanks in advance!
