I live in Atlanta and am in the process of buying a 97 eclipse GS with a blow engine. I would like to replace the engine with a new or low mileage 420A—preferably turbo. I don’t have many contacts for this type of thing. I am trying to figure out if it is worth it, and how much it will cost--so that I can make an offer on the car. Any suggestions how I should go about finding a 420A here in Atlanta and how much one would cost?
