With all the news surrounding the Nissan GT-R V-Spec, the progress on the Godzilla tuning front has been largely overlooked. According to a recent article in Japan's BestCar magazine, the Amuse team has broken the 600 hp mark (at the crank) with a combination of a high-flow exhaust and a tweaked ECU. There were no details on how the GT-R's computer was hacked, but Amuse was able to up the boost to 18 psi, resulting in an increase in output to 602.73 hp and 576.95 lb.-ft. of torque.

However, tuners are beginning to question how the stock gearbox will hold up under the strain of additional output. MCR, which brought out its GT-R for filming of Hot Version 93, has been exacting its own brand of punishment on its tuned GT-R and is worried how long the transmission will last. It's not clear if the tranny woes are due to the clutch plates or something else, but it's been all but confirmed that dual-clutch gearboxes have an issue with additional torque since the friction surface is much smaller than on a stock (read: single plate) clutch. MCR's best guesstimate is that the stock 'box might only be able to hold up to the additional power for 12 months before problems begin arise. Now, we're particularly interested in how Nissan is beefing up the tranny on the V-Spec to handle its rumored 600 hp.

      There's a reason the Tremec is so popular. It might not shift like a miata but boy can they take some abuse and are relatively easy to beef up i f need be.

      Now this new fangled flappy paddle stuff is going to be harder and more expensive to beef up. You can buy a beefed up Tremec for less than $3k. Guessing from my experience with exotic transmissions such as ZF's and Hewlands that the cost of a beefed up GT-R transmission would be well into the $30k range conservatively (Hewlands can cost upwards of $65k)

      Right, the tranny is going to be the weakest link. I'm going to hold off guessing where the breaking point will be until the V-Spec comes out, then we'll know if it has a whole new tranny unit or uses the same one as the normal GTR. If so, then there should be a small tuner buffer, if not then I suppose someones gonna have to make a T56 adapter.

      What are the dyno gains compared to a stock GT-R?

      I ask this because posting crank horsepower claims on a car that is generating realistically 50 to 70 bhp more than what the manufacturer estimates is useless.

      AHHHhhh. Nothing ever really changes does it? Back in my day of the late fifty/early 60's all of us "hot rodders" used to say that "everything breaks at it's weakest link". We put in bigger engines, (a 'Caddy mill in a Ford), only to find that the clutch needed to go. Then the rearend, then the driveshaft. And so on. Same today 'eh?

      Put a T56 in it and STFU already. That stock tranny will be toast in 1 year on stock hp... This will be like the dodge neon mess just way more expensive.

        Drivetrain components will always fail if you go past stock. Lingenfelter Corvettes will eat their differentials.

        There's no reason why the DCG can't handle the same as a manual. This situation is no different from Corvette.

        The ZR1's transaxle had to be beefed up as well to handle 600hp. So it wouldn't handgrenade like a Dodge Neon mess.

      I dont care, what people say that car is hot as hell in red... wonder how much this one is?

      wait wait... dsg has issues with extra torque past it's rated limit, this is news to me... old news that is for anyone who's tuned their dsg TT/GTI/GLI the last few years.

        The GT-R's engine is pushing waaaayyyyy more torque than a turbo VW.
