its a gamble man.
usually if u get an engine problem, they wont even attempt to fix it, but just have to get a new one for around 10 grand.
theres not much to do to it without causing some kind of damage.
and car being salvage, its a tough call, since many things will be miss aligned and usually it happens that you find out other things are bad and end up costing you a lot.
also, for instance, if you put bmw e36 or something like that in ebay search, you fing hundreds of pages and listings, try it with boxster....not many at all, and almost none used parts, so u have to rely on jacked up dealer prices, or dismantlers that also dont sell things for cheap.

good luck, but this doesnt sound like a good idea. nowdays u can get a nice clean title boxster for too damn cheap.
