Once the car got better gears and stuff, I was putting down about 15% more torque. Still limited to about 183. If I'd gotten the long-tubes, full exhaust, better intake and a tune, I may have gotten it to 190.

your car also had a V8 which makes it easier to reach higher speeds
the current 911 base model carrera reaches 180mph with 345hp.
so with a less restrictive exhaust on the 370z it should be able to reach that speed. not to mention it has more aggressive gearing and a higher redline with the mines VX ROM. i doubt it will be 3hp. it will most likely be a 10-20hp peak gain with much larger gains throughout the power band.
