I have done this conversion for a customer without a donor car, but I also have a "collection" of turbo parts accumulated over many years.
Like most else everyone on the board, if your name and location was not a top secret, you might be able to have someone help you with this project if you are serious?
Another factor to consider is this project would require at least $4000+, and that could increase dramatically if you are not familiar with a wrench and all the "wierd/different" things on this 28+ year old technology.
