Switzer Performance Innovation (SPI), a car tuning company from Ohio, have released details on their P700 package for the highly anticipated Nissan GT-R. With over 15 years experience tuning all different imports from Europe to Japan, Switzer Performance was able to get 700hp out of this GT-R, hence the ‘P700’. SPI is well-known for tuning Porsche’s and recently introduced the 1,000 hp Sledgehammer 997. However, for this project they aimed to maintain a reliable and everyday driver at 93 octane. At stock the new Nissan GT-R is able to produce 480 hp and 434 ft-lbs of torque. So the first major upgrade SPI decided to go with were brand new Garrett GT ball-bearing turbochargers with custom compressor wheels to increase the boost.
The additions of larger turbos and more boost brings the need for cooler air, so a large Monster intercooler was fitted with custom piping. To keep everything running stable, Switzer remapped the ECU and they claim that with all this extra power there isn’t extra stress on the drivetrain. The Nissan GT-R dynoed at over 700 hp at the crank, and to the wheels an impressive 626 hp and 583 ft-lbs of torque. This P700 Nissan GT-R performance package is available for a pricey $16,650 USD.
