We just wrapped up our first Greddy TT install and so far, I'm very impressed with this kit. The fitment was absolutely spot on and superb, and the quality of the components was top notch. The kit, as most of you know, features the TD06-20G turbocharger which can support 800hp easily. The car made 610whp@17psi and there is much more left in these turbos. As a reminder, or Dyno Dynamics Dyno reads much lower than most. A stock GT-R produces about 380-390whp on our dyno, for reference. Each PSI yielded a significant increase in power. Here are a few pics! Also, wanted to give a tip of the hat to SP Engineering. They did the initial install of the HKS GT570 kit and the workmanship and attention to detail was outstanding!

The car is a beast!

I don't see any transmission work on that mod list.

My first thought too.

The stock tranny can't handle 390hp, I don't see it lasting too with 600+ hp.

They definitely need to tune that thing, that low spot in the middle of the curve would concern me.

yeah that dip down to only 490hp would make you really slow.......lol

Well, granted, it's plenty fast, but the curve is nasty.

The power is fine but a dip like that can indicate a fueling issue. Fueling issues can lead to an engine blowing up issue, especially in a turbo car.

I wonder where the additional power is coming from with this engine. The boost they are using to get to 610hp is actually less than what Nissan claims the stock turbos produce.

I really WANT to like that car, the car in general, not just this particular vehicle...but I cant. It just doesnt seem right. If they get the fuel, tranny and power right, it will be nice, but its just "meh" to me.

Isn't the stock GTR making 460 or so RWHP?

Aren't they blowing up at that stock power level?

I would be much more impressed with a stock motor GTR that lost 1000lbs, yet was still streetable, without all the gadget bullshit.
