Mine's VX ROM (ECU flash) for Nissan 370Z (Fairlady Z34) 01.01.09

Supergoji

the E46 M3 can hit 175mph drag limited stock.
the new Z should be able to hit between 175 and 185mph.

hell i remember the Z32 was tested and it's limiter was removed and it hit 170mph+.
i believe.

I really honestly believe that it is governed to 160, not drag limited.

HIGHLY doubtful it will reach 185. MAYBE it might get to 170-175. My stock Trans Am put a LOT more power and torque down, weighed a hair over 3500 and was pretty aerodynamic for a muscle car. It'd get to about 180 before drag stopped it from pulling. We're talking at least 40HP and 90Lbs of torque more than the stock 370. 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.

Crash

^^^ My point exactly... With headers, better intake, and a good tune, the Z should be able to reach 180.

BTW, my car had 3.73's. The motor didn't work as hard to get me to higher speeds, but I have to admit, around 150MPH I was doing 4000RPM! Not much more room since it red-lined at 6400. I assume I was doing about 5800 when I hit 180... Couldn't tell EXACTLY how fast I was going since my speedo only went to 155.

now do you have a 300zx twin turbo?
it's much easier to reach those speeds with bolt on's on a turbo Z hhehe.

400whp is still accessible from our little T25/T2 hybrid turbos haha.
im hoping for 450whp from my stockers, im also going to be running the stock compression from the NA (10.5:1)

Crash

No. My 90 Z is NA. I bought it when turbos were too expensive for me. I was later going to put in a JDM turbo motor. ($1600 with trans)

But then I saw the 370z and decided to hold off.

dude swap, then get an interior from tunerD, then get a full exhaust from Specialtyz, doolz intake from ash, upgraded intercoolers, MSP manifolds and GT2860'rs the same turbos that the R34 N1 has, and some wheels and suspension and you'll be happy as a lark.

and much faster than a 370Z, look better, older people will respect your Z because they know it's fast. and your resale value if you keep it in good condition will be about 15k or more for years to come with all those mods.

which is more than i can say for older 350z's, or when the 370z gets a few years older.
