Is anyone offering ready-to-fly Subaru conversions any more? There was a time that the homebuilt aviation magazines were full of them. I am particularly interested in the more modest, four-cylinder conversions rather than the more powerful, expensive six-cylinder models. Thanks!

This may be outside your budget and I'm not sure if any have flown yet: http://autopsrus.com/subaru-ej25-fwf-package

I'm curious why you're looking specifically for a Subaru conversion? What specs did you see and like that made you think of Subaru and not one of the more common (now) Corvair, Honda (Viking), or VW?

VW has always been my go to solution and still seems to make the most sense for a VP-2 or other plane designed originally designed for a VW, but I was curious if anyone is still offering a relatively low-cost, low-power Subaru conversion anymore, maybe something based on the current generation 2.0 liter base model Impreza engine? Viking seems too spendy and Corvair a bit heavy, but I am watching some of the Suzuki developments closely.

The EJ engines are way heavier than a VW and make about double the hp so they are in a different class. An EA81 might work. Ram Engines builds those but they are not inexpensive either. Aeromomentum Suzuki is where I would head.

Thanks, Ross. The RAM EA81 conversion looks great but at $14k without a PSRU or accessories it's also no cheaper than a Rotax. Yes, I have my eye on Aeromomentum Suzuki conversions particularly the anounced but not yet released 75 hp AM10 three-cylinder model. If they can keep the cost and weight at or under VW levels then I think it would be an interesting option for many traditionally VW-powered designs.

I would like to see a E81 cut down like a VW to twin cylinders and hope for about 45 HP it would be a good match for my T-mono if the weight was bearable.:p:

The Aeromomentum Suzuki looks like a good option if you don't absolutely need a boxer layout; I too am looking at the 75hp advertised at $7k and think if it's remotely close on those it should destroy most any comparable ready-built VW in performance/dollar. And it's got a redrive turning the blades 2300rpm at that power output too, so that's a big plus.

Of course Verner has some options too :lick: but, of course, its a different regime of price/performance and may require a different approach to the FWF.

Have you seen the size of a T-mono firewall? Sure is not much room for any engine to fit the HP range. the first one I believe flew with a 38 hp engine "J99 J.A.P.

Oh well for the TM I'm not sure any of the in line options fit. I personally would see if a Verner 5VW or Pegasus O-100 could do if you're looking for that power range. Heck the 3VW should beat a half VW at the very least.

I have a couple stock 1600 VW single ports that are sitting waiting for the bird to be finished but it would be neat to come up with something not tried on the Mono yet.
