if you plan on making lots and lots of power in the future then a 75MM is best. But if you are just a daily driver and you dont plan on making too much power in the future then a 70mm will be better. Accufab has great products for throttle bodies.
The intake plenum will direct better airflow into your engine. id say get one.

75mm is not too big, it just doesn't need that much for a stock GT. The extra size does not hurt or help (for now). It will work awesome for a supercharger, 70 mm is too small.
