Hi
I have just blown my engine on a 01 plate bug ,due to bad mapping done before i bought the car.
it is now at John Pye Motors in bishop Aukland ,they build engines for rally subarus .
Try giving them a call ,they may have a second hand engine, or will rebuild yours.
They are on the web ,beware you could buy a load of trouble with a second hand engine,
they come very highly recommended, and have asked all the right questions.
cant wait to get it back.
good luck Frenchsue
