Question WRX Airplanes

Some of you are familiar with the fact that 2.5ltr engines are hard to come by because people with airplanes tend to buy up the engines in bulk.

So I was thinking (Uh oh! ), when WRX's starting crashing and ending up in junkyards, do you think airplane hobbyists will start putting WRX engines in their airplanes? Just curious! I guess a 22b powered airplane would be kinda odd.

Turbo-charged engines on airplanes are tuned differently. On the ground turbos are turned down during take-off and they still make maximum take-off power. Gradually, the turbo is turned up as altitude increases to maintain lower altitude power in the upper altitudes due to the density of the air. Just some more usefulless info.

I do know one thing that has become increasingly popular to do with the engines. Alot of people are starting to use them when building sand-rails. Because of the size, reliability and potential for power, they are pretty popular.
I actually know of one place called Tatum Motorsports in Phoenix that imports WRX motors out of Australia to put in their rails.

That's nothing new. If you guys remember, our beloved engines started out as aircraft engines! Subaru reatined the same layout, but adapted them for automotive use. The engines were used in the Fuji FA-200 Aero Subaru, back in the 60's. That airplane is still around here and there. In fact, I think it'd be cool if I could find one, apparently, it's a good little 4-place airplane. That way I'd have both a Subaru Impreza and Fuji Aero Subaru So the engine conversion from aero to auto or auto to aero isn't very difficult.
Gotta fly!

I've seen a lot of airplane builders sites and they seem to prefer the EA81 over all other engine choices (including the EJ22). I think maybe because it is lighter than the others. I haven't heard of anyone using EJ25s but I guess I haven't looked at those sites in a while.

I think they are also looking for cheap and plentiful...neither of which describes the EJ20.

How bout this EG33 conversion?

You mean like this EJ22??

Or this intercooled intake manifold for a EA82?
