stock size is 48mm

unless you're pumping out 400 or so horsepower, then a throttle body will do you absolutely no good. spend the money somewhere else

I wouldn't mess with a new TB unless you go for a 52mm and port the front of the intake to accommodate it. That said, unless you're making some decent power you're not going to outflow the stock TB.
