Bolt on TURBO??????

Hey whats up guys. I have a question for all of you guys. A buddy of mine just purchased an NT 98 Eclipse Spyder GS with the 4G64 . He told me that the head off of a turbo eclipse(4G63) will bolt right on to to his engine. He also said that the Turbo and all its components would also bolt right on to the car. Is that true? Or is he full of shyt? ?And if so theres no other modification needed to convert his car to a turbo other then taking a complete turbo system off of a turbo eclipse?

Let me know what you guys know about the compatibility of the 4G64 and the 4G63.....If it can be done fairly easy he wants to begin looking for parts to turbo his car.
Thanks for the help guys.

The DOHC head is a swap that has been done before. 4G64s are not too hard to turbocharge, getting the [arts is harder at times. Here are some good links:
