Yes, that's a good setup. Top end (theoretically) is above 200MPH with this current gearing, however, you'd need a LOT more power to get the car to 200MPH. Lets say for argument's sake, double the power you've currently got. The faster you go, the more drag you have... Drag is caused by 2 different issues on the car: 1) the aerodynamics of the car's body, and 2) the rolling resistance of the tires. The faster you go, the more both of these dragging variables increase. There is actually math you can do to figure exactly how much power you'll need to beat these forces and get the car to 200MPH.
Keep this in mind: A Corvette ZR1 weighs about 100Lbs more than the 370Z and has 638HP. It's drag coefficient is LOWER than the Z's and the rolling resistance is almost identical. The top speed on the ZR1 is approx 206MPH. Keep in mind, that car was designed to reach that speed and has the correct suspension to do so. A Z would need a suspension over-haul, better aerodynamics, and WAY better tires to achieve the same goal with 640HP. The Z is not designed for straight line performance. It's designed for the canyons, and as far as I know, there's not a single canyon you can break 130MPH in.
