Hey,
Debating a 2009 or 2010 GTR. I normally use Sunoco 94 with my 911 or 91 at Shell. Just curious if the 91 octane is enough for it. Sunoco is selling most of their stations in Canada so 94 maybe getting scarce. Thanks,

 

Of course 91 is enough for a bone stock GT-R. If you plan on tuning the car, make sure the tuner sets it for 91 octane. I have heard that the setups with larger turbos can have trouble though on 91 so you may have to keep it a bit more conservative.

 

We have a P800 package on a car in California running 91 craptane and making 650awhp.

We are working on a custom water methanol control unit and system that will handle 100% methanol, that should help you guys. It won't be cheap but it will meet our standards.

 

91 is all I use because it is all that I have available. Works great!

 

try some E85 if they have it around your area, wth out a tune can run 30% and the rest 91.
