I saw a pic of the gt42 on a recent post about a week or to ago and the gt42 look huge. People where saying the turbo was wayt to big for the street, and would take bridgeport and 20b. If this turbo is bigger that gt66 and gt72, hoe much bigger?? btw does anybody go with such like a gt40, gt4042??? most importanted of all HOW MUCH ARE THESE GT AN INNOVATIVE TURBOS???
