For a long time now, news of the Nissan GT-R SpecV has been making the rounds, with many expecting the new model to outdo even the mighty Chevrolet Corvette ZR1 when it finally takes to the Nurburgring for an official run. Part of these rumors was the assumption that the SpecV model would not be receiving any significant power upgrades over the standard GT-R, but would instead focus on improving driving dynamics through weight reduction and handling modifications - assumptions, it appears, that may have been incorrect judging from recent pictures taken by Japanese tuner Garage Saurus comparing a standard GT-R with the SpecV.

The image compares the exhaust wheels of the standard Series II GT-R and the new SpecV model, and while Nissan has never mentioned that the turbochargers were different in the new SpecV, it’s plain to see that the SpecV has a larger exhaust wheel with a flatter blade compared to the standard GT-R.

The finding gives hope to tuners, who are hoping it’s an indication that the turbochargers in the SpecV will be able to churn out more power before they reach their limit. More importantly, it could mean that the SpecV model actually produces more power than the claimed 485hp (362kW). It wouldn't be the first time that Nissan has underrated the output of its GT-R models as the practice was common for variants of the previous R34 model due to Japan’s voluntary power limit of 276hp (206kW).

Why Nissan failed to mention such a significant difference between the turbo units in the SpecV and the GT-R is anyone's guess, but it does go some way to explaining why individual component pricing for the SpecV shows the turbochargers listed as a separate part with a higher cost than the units on the regular GT-R.

    I love the GT-R, but hate how heavy it is. I wish Nissan would take this amazing drivetrain and all the electronics and stick into a bespoke lightweight chassis that's at least 1k lbs lighter. Preferably more so.
