I've read that Nissan has taken measures to thwart ECU mods and that all the innovative engineering on the new GTR may make it harder to mod than other turbo cars (which in general can be modded easily for more power).

Anyone have any info on this? I see that Mine's is doing some work in Japan, but no quantitative data on gains.

Any U.S. tuners planning to offer power kits / tuning?

Cobb Tuning has had their JDM R35 GTR cracked for some time now; from their blog:

"Some claims had been made to suggest the new Nissan GT-R ECU was encrypted and ‘uncrackable’. Well folks, we’ve ‘cracked’ it. Our own GT-R is a JDM version with the fun-sapping 180 kph (112mph) speed limiter. Thankfully, it can now be removed. We’ll continue to do more in-house testing and hopefully get some beta AccessPORTs out to the other two JDM GT-Rs in the US inflicted with the same speed limiter woes. By the time North American spec cars arrive, we should be well prepared and practiced in the art of tuning the GT-R’s ECU.
Stay tuned for more tuning updates as we begin to see what can be extracted from the new GT-R with some ECU tuning!"

Here's the blog: http://blogs.cobbtuning.com/

If you follow the pages in the blog, you'll see their prototypes for exhaust, intakes, etc.

Cobb will surely produce some great parts/ECU management for the GTR.

MINE'S has also cracked the ECU and did it some time ago. It is believed that they worked with nissan in order to crack it. They have produced a 550 hp GT-R that is reliable with a higher boost level. MCR has had problems with the transmission and their GT-R had around 600 hp.

from what ive read they're giving it modest increases in power, but the transmission can't hold much above 600 hp without reliability issues

then its the usual onslaught of cf parts, wheels, intakes exhausts...

It will be interesting to see how the transmission will change for the added power on the v-spec.

My thoughts exactly...

Well, 600HP is a decent start.

EXTREME

This car is 480 rated at the moment..and its a kick ***... So, if its 600 what the results would be
I would be really happy to have it at 600HP and realiable

That's what I thought when I bumped my 997TT from 480 to 600HP. Power is a funny thing. After a couple of weeks you get used to it and start thinking "man, am I down on power today?"

Now I am at 700HP and am happy....for now.
