Most of this week's Nissan GT-R tuning news has been coming out of the Tokyo Auto Salon, but South Side Performance is making its own headlines. The tuning firm based in Sioux Falls, South Dakota, is offering a set of upgraded stock turbochargers for the GT-R that have the potential to boost output to 820 hp when used in conjunction with other (undisclosed) performance modifications.
The upgrade consists of swapping out the stock turbos' center section with remachined compressor and turbine housings, sized 68mm and 53.8mm, respectively. The aluminum compressor wheel is good for up to 32 psi of boost, and since the basic hardware remains, the swap appears to be a simple bolt-on affair. According to South Side, the turbos make more power at stock boost levels and provide a linear power band throughout the rev range.
GT-RR.com is distributing the GTR820RR kit for South Side, and owners can send their stock turbos and $6,499 for the upgrade, with an approximate turnaround time of one week. Of course, the next question is: how will the stock clutches and transmission hold up to the additional power? Check out the images of the setup in the gallery below and hit the jump for the press release.

SOUTH SIDE PERFORMANCE INTRODUCES GTR820RR TURBO UPGRADE FOR NISSAN'S R35 GTR - CAPABLE OF MAKING 820* CRANK HP!
Sioux Falls, South Dakota (January 16, 2009) – South Side Performance is offering, for the first time in the U.S., a turbo upgrade capable of 820 HP* for Nissan's newest supercar.
After months of R and D, South Side Performance have found a turbo combination with greater efficiency, faster spooling, and a stock style fitment for ease of installation. The result is a kit capable of making 820 HP* (when combined with other modifications). Due to the high efficiency of these turbos, GTR owners can run lower boost and make more power. The result is one of the first true big power upgrades available for the R35 GTR.
These Garrett ball bearing turbos are a direct bolt-on that utilize CHRA oil lube and are water cooled. They require only one line to be changed and can be properly installed with basic tools and equipment. The price of the kit includes the machining each of the stock turbos and installation of an upgraded actuator, 53.8 mm turbine wheel, and 68 mm high pressure billet aluminum compressor wheel which is efficient up to 32 PSI.
The turbos were specifically designed to bring bigger power at lower boost and to utilize the fastest spooling turbos available for the size and application. The result is a turbo that makes more power at stock boost levels and starts making boost lower RPM's than stock. This combination allows your GTR to enjoy the benefits of power lower in the power band that continues all the way to redline.
Price and Availability:
This upgrade is available exclusively from our distributor www.GT-RR.com and will be available with exchange of the stock turbos for $6,499.00 or without exchange for an additional core charge. Turnaround time will be minimal, usually about one working week.
