I am starting to go down this road, and would like to do it once. (heard that one before?) How much would it reasonably take to upgrade the stock 06 engine on my gt and then go with serious horsepower? Honestly though, for a daily driver I would only like about 500 horses...but how hard would it be to upgrade my existing engine? I am located in Maine, without much here for serious engine builders.
Many thanks,
Doc
