Nissan GT-R by Switzer Performance Innovations (SPI)

Article by Christian A., on August 26, 2010

The auto press have been busy in previous months as they spent enormous time contrasting the Porsche turbocharged 997 and the newest Nissan GT-R. The majority consensus favored the Nissan GT-R over the performance icon from Stuttgart. A year succeeding its introduction, the first tuner GT-Rs are beginning to reach customers giving rise to another question: how does a tuned GT-R compare to a tuned Porsche? Early this year, Tym Switzer and his tuning firm in Oberlin, Ohio were catapulted to world prominence when they introduced the 1,000 hp SLEDGEHAMMER 997.

The tuning company, backed by 15 years of experience tuning high-performance cars from Europe to Japan, is quite in the position to answer the query.

Switzer points out that the Nissan monster is quite distinct from the Porsche. It is an all-weather, four-seater supercar which could appeal to the same kind of customers as the Porsche 997. However, the GT-R is more than just a "digital" ride. Both cars come close to each other in terms of final performance.

In the last couple of months Switzer has been conscientiously putting the GTR under a microscope, developing a series of practical, high-performance bolt-ons targeted at making a street-legal GT--R performance pack that does not require GT-R owners to compromise trustworthiness and driving pleasure.

The latest Switzer package, dubbed the P700, comes with 700hp on 93 octane pump gasoline. It was the result of determining what the GT-R was really capable of and of what was really taking place inside its platform.

The initial step taken by Switzer was the logging of a wide range of data and analysis. The test included the monitoring of temperature changes, pressure drops, everything that can be learned about the car. Switzer substituted the factory turbos with application-focused bespoke units and their own special MONSTER intercooler pack, then incrementally raised the boost, evaluating data over and over gain.

In the process they overshot the standard ECU calibration and hardware limits which prompted them to make the necessary components and restart the data gathering all over again.

Coming with an excess of 626 awhp and 583lb-ft of awtq on tap, the P700 GT-R by Switzer is absolutely able to offer a driving experience that is above and beyond the regular Nissan GTR without subjecting the GT-R's driveline to needless stress. The performance package has a $16,650 sticker price.
