b-on-b 5.0

was wondering on what power gains it would be to go from the stock 55mm trottle body and egr to like a 70 or 75mm trottle body and egr on a gt40 intake and 10 psi of boost....motor is 93 cobra motor...is it worth the $200 bucks or not reli?
and anyone know what the opening end of the gt40 is in mm? (the opening where egr and trottle body bolt to)

It will help the motor breath more. You may see the psi drop but not likely, I don't know if its worth 200 dollars, but look online via ebay or craigslist, or some take off parts for one.

if the TB is from the 93 Cobra motor then it's a 65mm stock.
