Here's the word from our friend with the Subaru powered '79:
I have tons of pictures of the conversion process. The Subey gets around 21/22 mp(US)gallon. Best was a tank that AVERAGED over 80mph and gave me 24mpg! Power is more than you'll ever need. How about 80mph in 3rd gear? Speedo will wrap in 4th. 3rd gear starts on level ground (not recommended but definitely do-able!) 2nd gear starts easy and smooth. Instant reaction / power out of corners twice as fast as you ever took them in a bus before!
The "SET" is for sale for $4,000 (any reasonable offer considered however.) The brown 1979 bus (the Busaru) was in when Mt. St. Helens erupted and all double body areas filled with ash. It was okay in that dry environment - all that happened was the ash ground away any surface treatment of the metal... Once it moved to Western Washington (Seattle area) the ash took on moisture and acted as a sponge, holding it there and eventually rusting out all those areas. The grey bus is a 1974, was apparently used by the Oregon Dept. of Corrections as a body repair training vehicle. It has only a very few spots where there may be a millimeter of bondo filler, but is virtually straight. It was shot with primer only - probably 15 years ago (?) but never shot with a seal coat, so there is surface rust - meaning it has to be stripped once again before using. It is a "rolling body" with no engine or transaxle.
There is the first Subaru engine ready for rebuilding, a set of 4 Nokian Hakka , mounted, with about 1.5 winters on them (the best snow tires on Earth, bar none!) Espar diesel heater with one winter use on it, the brown bus has a 1200 Watt inverter built in for the 1000 .
I'm sure he would like to sell the whole lot to one person, but I believe he'd sell the rolling body, engine and Bussy as individuals. Other than that, though, I think that's as far as he'd go parting-out wise. Personally, I'd love the Espar diesel heater.... and those snow tires. Anyway, let me know if you're interested, and I'll put you together with him. If you want to unload the tires and the heater along the way, I'm interested in talking to you.
Just for grins, check out the "spare tire" on the nose of the brown bus. That is actually a disguised radiator. Pretty frickin' sweet.
