nissans gtr

found this one on an other forum i post on.



Japanese GT-Rs are speed-limited for the street: As has been widely reported, unless it's driven on a preapproved racetrack, a stock Japanese-spec GT-R is limited to 180 kph (111.8 mph) with the factory settings. GPS sensors in the navigation system track vehicle position and communicate with the ECU. Try to exceed 180 kph, and a warning light will appear on the instrument panel. Only shutting the car off and restarting it will get the light to disappear.

But can be run all-out at the track: Running a GT-R at the track requires scrolling through menus in the on-board computer and selecting the racetrack option that bypasses the speed limiter. Only then can the car be run to its full potential.

Though it'll cost you: Once the track day is over, owners who have run their GT-Rs over the speed limit are required to take them to a preapproved Nissan High Performance Center for a safety check. Failure to perform this $1000 service will void the factory warranty.

As for the wheel and tire rumor: That the factory wheels cannot be removed without sending an error code to the ECU, MINE'S has proven this myth wrong. It's been able to take off wheels, rotate them, and even change to higher-performance, non-run-flat tires. It did have to take the wheels to the Nissan dealership to get the job done at great expense; MINE'S ended up paying about $230 per wheel in labor.

Putting aftermarket rims on a GT-R is a different story: Because of a sensor located near the valve stem in each wheel, it isn't possible for the car to run on aftermarket rims without throwing an error code. All blinged-out GT-Rs at Auto Salon got there on stockers and only then were the shoes changed.

Some mild mods are possible: MINE'S has modified the exhaust system and a replacement air-filter element, both of which have reportedly made substantial extra power. It's also upgraded the brake rotors and switched to GT-R's suspension system to a coil-over system with no ECU problems.

But not all: MINE'S has tried replacing the factory air box and intake system with a high-flow cone-style system, but found its car will not run right. Raising the boost pressure on the twin turbos, a common way to increase power, also triggered errors in the extremely sensitive ECU.





with that said... I would like to own one if i had the extra $$ to it, but i wanted the car more before reading this (even though i can't really afford it if i want to eat)

Re: nissans gtr

Why in the world would they do all this crap? Maybe I'm wrong, but I thought a huge portion of this cars fame came from the tuner community. The fact that they've turned every tiny mod/maintenance issue into an overpriced circus seems to just spit in the face of their target market.

Wow... yeah. If I had the kind of money to afford that I would turn the other way. Not being able to even change the wheels? Such BS.

Re: nissans gtr

All along, I've thought that is ridiculous. And, I never understood the "cachet" of the GTR. It's a great performer, but the value of the vehicle compared to a 911 Turbo, Corvette, Z06, R8, etc... is completely lost when Nissan and their lawyers (not just in the US!) ruin the joys of ownership. I could understand if it was a leased vehicle...be better off leasing or renting the vehicle and not having to deal with as many issues. And the value of the vehicle, compared to others (at higher prices) is completely lost.

This car is/has been overhyped and this only makes it more so. Performance on paper and making competitive numbers is one thing, the joy of ownership is a whole other thing...

For sure...70-80K for all that hassle and they still slap a Nissan tag on my car? No thanks.

No track day unless you have a service performed after? I'd rather buy the Z06.

Re: nissans gtr

this GPS business will not be on the cars over here. Changing wheels will not be a large issue, but why would you want or need to change those wheels. The car is so bloody fast stock that the only thing I would maybe want to change is the tires.
