there's a sale at jdm honda parts for $120 for a JG ported 4mm Throttle Body w/core. is this a good upgrade that would gain me say 5 ponies?

I'm sure he meant 4mm oversize. $120 sounds almost too cheap to be true.

I've heard of people have problems with the fitment of the throttle plate on JG throttle bodies. The throttle plate is the most important part of the process of boring out a TB since an improper fit will cause all kinds of problems. From my experience in the NA world, I can say that RC Engineering is probably the most respected name in bored out throttle bodies. They charge $225 to take your existing core and bore it out to 64mm.

Here's a pic of mine:

A throttle body would definetly help, Better throttle response, more air getting into the charger quicker. I have a BBK 62mm TB w\ throttle rotor, you wrote"4mm" not right. check the size.
