I top out at 120 and I dont know where or how to properly remove my rev limiter or if its safe to do so ....any ideas?

no, but it was only slightly modified and driven really really really hard

ther revlimiter is built into the ecu the only way to remove it is to buy a new racing ecu they come with out speed limiters and boosts the rev limiter from 6750 to 7250 on a sohc and on dohc boost 7250 to some where around 7700

Lies.

You can also remove it by wiring a switch into the power to your VSS. This will, however, kill your speedometer and odometer while the switch is off.
