I'd imagine stock turbo's if he didnt mention otherwise,

anyone gonna get a 2013 anytime soon to tune?

^^ I figured that as well, but this car seems to be holding 19psi all the way to redline. I haven't tuned a 2012 yet, but the previous years will usually taper to 14-15psi by redline.

can only imagine what that feels like in the midrange

This is a stock motor car with our Stage 2 turbos and bolt-ons. I tend to stop pushing these cars at 600 - 615 on our dyno due to the rods on the GTR. They bend and eventually fail. He is going to do a 4L Cosworth motor. At that time we will turn up the boost on the Stage 3 turbo kit(GT35R). Here is a rough list:

Akuma Stage 2 turbos...71mm billet wheel, GT28 bual ball bearing CHRA
Akuma IC Pipe Kit
Akuma BM Intakes
Akuma SD Cobb Tune on 93 Octane
Cobb DP
Akuma Mid pipe
HKS Cat back
FIC 1100 Inj
ETS FMIC Core
Dodson Sportsman Complete Clutch Assy

Overall looks great. But you can see the torque pick up as she leans out around 4500, although based on the min/max you afr goes from 12.1 to 11.0 i'm not sure what the actual fluctuation is. The smoothing is cranked up(55), i'm sure you would be able to see it better with smoothing down around 10/15.


Power is great for a stock motor with some bolt ons, the torque looks like a blast to drive. And i'm sure that's why the stock rods hate life, near 600 wtq is a ton!

Nice job John!! What does this turbo package consist of? Loving the power of e85 on my stock turbo's but not the difficulty of driving 1.5 hours each way for the ethanol. Would love the same power I have now on pump gas and 50-100 more for the occaional e85 usage.

Yea an hour and a half drive each way is no fun, but doing it in a GT-R helps a little haha!!! We've actually had a customer or 2 test the e85 at Newark Int. Airport and we saw test batches as low as e77. If you interested in the turbo set-up let me know i can get you a full spec list of them.
