The engine is a Subaru Legacy 135 hp 2.2 L
I am an experimental guy (and I own 2 Subaru's) and I would not venture into the alternative engine world...
Recommend passing on that one.
There are other experimentals that are not the higher end newer shinier faster more common models which will meet you price point and be among the most economical to operate of anything out there while cruising in the 140-200 mph range. A few have been mentioned; of these the vari-eze is likely the most well known which will likely translate into an easier sale when the time comes to move on.
