would my modification set up have any benefits from getting a 52 or 58 mm throttle body or would i probably lose horsepower???

I wouldn't do it.

Keep in mind that your intake holes are only 52mm, so you're wasting $$$ if you get a 58mm unless you enlarge the holes in your intake.

I'd spend the $$$ somewhere else first.

Cool

No! I wouldn't worry about a throttle body until you do a head/cam install. And unless you go big, you will never need a 58mm unit. A 52mm throttle body flows about 750CFM. More than enough for most engines.
