Motor Trend Article
"The buzz at this year's Salon centered around Godzilla's attack on Tokyo; Nissan's GT-R recently went on sale in Japan and has become the talk of auto scribes and tuners worldwide, but some of the recent chatter about the car has been for reasons the company would probably rather not discuss.
Rumors abound that Nissan has effectively castrated the GT-R by restricting the kinds of modifications that can be done to the car, as well as limiting how owners could drive them. How Draconian are Nissan's controls? Word is the company didn't even want to see aftermarket wheels on any of the GT-Rs at the show."
"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."
"The modified GT-R was able to run at 192.6 mph (310 kph) while the factory spec GT-R was unable to go past 111.8 mph. Niikura-san told us he's in the last stages of overcoming the boost and speed limit as well as making it possible to make adjustments to VTC (variable cam timing system), air/fuel ratio and throttle position. Since our visit, reports have surfaced that MINE'S has just released a version of its VX-ROM product designed to override the ECU's limiter function."
I have been hearing that the ECU is pretty hardcore. Talk about immobilizer and such. I hear this rumor, we might be finding out in a few weeks exactly how hard this nut is to crack.
