First off, that's a GTE throttle body and won't mate up.
Second, on a N/A it would be a waste of money. You need to remember that the trade off for volume is velocity. In a N/A engine you want velocity, not a much slower moving denser charge. In "by the seat of your pants" testing there really would be no noticeable difference but any perceived gain is purely imagination.
The only throttle body mod I've seen done that I am unsure of but would like to see a LOT more data on is a dual throttle body... one on each side of the Y pipe's exit. I've also seen a dual butterfly TB from a Mustang fitted, but I suspect there would actually be a loss, smaller opening area and a lot of angled surface area to slow the air and create turbulence.
