I don't have a Mk3, but I do have a 2.0 ABA I am selling, complete with all wiring harnesses, computer, and everything you would need to do a swap. its already torn down and inspected and organized and catagorized. block is in excellent shape and pistons have a bit of wear on them but could easily be reused with some new rings. bearings are still in good shape, too but of course I would recommend you change those out too.
I have everything boxed and ready to go for $300 OBO. comes with everything
this was going to be a swap for my mk2 GTI, but I ran out of money and need to pay bills first
PM me if interested.
