Yesterday I took the first step toward starting an engine  conversion. I
had seriously considered Bostig and Subaru, both fine  conversions. I've
driven a full Westy with a Subaru 2.5 and it was amazing.  But in the end, there
desire to keep it all VW won out. I found and purchased  the later ('83-up)
diesel engine carrier bars, engine mounts, diesel oil pan,  and a couple of
other items. Now, I know I also need the Kennedy adapter plate  too, once I
decide which in VW engine is going in there. I'm sure there are  plenty of
sites which detail doing this conversion, but if anyone can point me  to one
please do! Also looking for an engine to buy-local to the Washington DC
area. My old 1.9 is still humming away, runs like a sewing machine, but the
right head is weeping coolant (for over 10 years! Yes, 10 years) and I just
need/want more power. Mine is an '85 Weekender, automatic, power steering and
 a/c (which I'd like to keep) Thanks!
