July 5, 200619 yr riped over this on the svx site. There is a great cutaway of the svx engine and other technical info, just ignore all the airplane stuff nipper

July 5, 200619 yr I'm more than a bit curious as to why the EG33 was discontinued with the SVX and Subaru started fresh with the EZ30 when they needed an H6 for the Outback. Was the EG33 too expensive to manufacture, was it too big for the chassis, or was there some other reason?
July 5, 200619 yr Author noise vibration and harshness i guess. The svx was a soobt engine with 2 extra cylinders, where as the H6 was a purpously built 6 cylinder. Thats my best guess nippper
July 5, 200619 yr The EZ30 was especially designed to fit in the same engine bay as a 2.5L, so they could offer it as an "option". Using a timing chain instead of serpentine belt made it over 2" shorter (front to back) than other 6 cyls. That engine is due to be a major leaker. Something like 49 bolts hold the front chain cover on: and they have to come off in a very specific order. If (and when) the chain goes, it's gonna take out a whole bunch of metal! It may yet prove to be quite reliable, but I'd advise being very pro-active on maintenance, because when it goes, it's gonna go in a big way! Emily http://www.ccrengines.com

Emily http://www.ccrengines.com its actually 110, yup count them, 110 bolts. Hate to see THAT bill for the timing chain. nipper
July 5, 200619 yr repairing cars looks like childs play compared to the stuff that guy is doing.. after all if you mess up your car the worst that can happen is your stuck on the side of the road.. if you mess up this stuff, you drop from the sky
July 5, 200619 yr It is an impressive bit of work he's doing but if I were to do it, I would choose the 2.0 turbo from the WRX. It would be smaller and lighter then the 3.3 and turbos are idealy suited to high altitudes. I'm amazed people still use the Lycomings and Continentals. Even when I learned to fly in the late 70's, the were considered old. Now they are antiques ( akin to a VW beetle motor.)
