Nismo Upgrades the 2010 Nissan GT-R

If the 485 horsepower provided by Nissan GT-R's engine seems just not to be enough, Nismo, the tuning arm of the Japanese manufacturer has just the right thing for you. According to pistonheads.com, the GT-R is now eligible for both an ECU and transmission upgrades.

The ECU chip upgrade is intended to increase maximum boost pressure by 0.1 bar or 1.5 PSI. This in turn improves low end torque. For the transmission, the upgrade, called Transmission Control Module, will allow for quicker downshifts and increase the electronically limited speed to 200 mph (321 km/hour).

Unfortunatelly, at least for the next few months, the upgrades will not be available outside Japan. The Japanese are in for a surprise as well, as the two upgrades cannot be purchased but only rented.

Getting your GT-R upgraded for the next two years will cost 294,000 Yen ($3,000). After that, you can get the same level of performance by paying $340 every year. The good news is that the warranty for the tweaked vehicles will not be affected.

In turn, Nissan will release some new tweaks for the older GT-R versions as well. For the first GT-R, the company will provide revised Bilstein shock absorbers, new front and rear springs, and new transmission and engine mounts.

And if you watched and weeped as the GT-R beat the Nurburgring record in April, you will be pleased to know that a piece of that car can be yours. Nissan will make available the lightweight 20-inch alloy wheels used for the occasion.
