The EA82 is an OHC engine using timing belts to drive the single-camshaft per bank. These engines use hydraulic valve lash adjusters (aka HVLA, HLA) to maintain zero valve clearance. The timing belts are less durable than the EA81's gear-drive, and are subject to breakage and engine stoppage. The good news is that EA82-series are "non-interference": The valves will not contact the piston crown if/when the t-belt beaks.
Both engines were available carbureted, and also turbocharged with MPFI (though EA81 turbos are not common). The EA82 was also available naturally aspirated with MPFI and with SPFI. In general, the EA82 produces more power than the EA81.
Both engines are prone to oil leaks (lots of vertical engine joints) and headgasket issues, HGs more so on the EA82s. Neither engine enjoys overheating, so cooling system is important. As prev stated, timing belt breakage can occur on the EA82 (regular maintenenace mitigates this problem).
Given good maintenance and avoiding overheating, both engines are durable. It is not uncommon for them to run 200-300k miles before needing major attention, and original honing marks are often/usually visible on cylinder walls after 150-200k miles.

I found this site and am working on a new project, A Doran 3wheeler. It uses a 1980-1989 Subaru flat 4 and 2wheel drive 5 speed transmission. I do not have any experience with the Subaru engine and am looking for any insite you may have. Such as are thier any years I should steer clear of? I would like to find a complete doner auto . Thanks John
Good luck!! Please post pics as you go. Trikes are so ***************in!! I've loved them for over 30 years now since I first saw a Mersherschmidt (SP) parked buy the curb in London at that time. Check out some of these tilters http://www.maxmatic.com/ttw_moto.htm and http://www.3wheelers.com/enter.html Cheers Pesky

That is so strange...I saw one of those Unisport 198's last weekend.
It lives near me? I didn't know what it was till I went to the link...
Now I'm going to have to go take a look and see what is powering it?

Got to wonder what the 0 - 60 is on that thing
Just plain cool!

top speed: 140mph
6 speeds and 900 pounds of yikes. I'd still rather have the sti atv.
