With talk of the all-new R36 GT-R model potentially being shelved, it may be left to tuning firms such as SP Engineering (SPE) to tweak the current R35 generation and keep it competitive with the latest supercars.

Godzilla's base price is around the $100,000 mark, but for an additional investment of $29k, SPE will gladly rework the engine to give it an additional 300 hp at the wheels and add some carbon-fiber elements (including a fat rear wing). The turbocharged 3.8-liter V6 can also be bored out to 4.3-liters upon request. Jay Leno gets the custom tuned 2010 Nissan GT-R into his garage for the lowdown on the modifications from SPE's head man before hitting the road to experience the new package.
