It's most likely not a speed limiter

But rather a rev limiter. Does your car have a tach? If it is indeed a rev limiter, I wouldn't risk removing it.

I miss my good old Sentra E! No A/C no power steering. It's just like maxpower said. If I had the tools and the time, I'd pull out of the mentioned items from my GXE.
