Really considering an intercooled procharger 7psi C2 for my '05 G35. I know it will void the engine warranty; but will it hold together? Any info on the reliability of a Supercharged VQ engine?

You should be fine with that.

I have 37,000 miles on my Coupe with an Intercooled Vortech S/C. Have never needed ANY engine service. I frequently use my car for SCCA sponsored autocross and road course events. I allow the rev limiter to judge my shift points and with the added grip of R compound tires on race days put much of the added torque to the ground. The dyno indicated a real need to remove the platinum plugs (smoothed out with copper plugs).Even with the stock tune I'd reccomend 93 octane fuel. I had heard of some bottom end (rod) failures but would have to believe this was due to improper tuning or low octane fuel. Also I use only Mobil One synthetic motor oil. And if I might add.....it hauls *** !!Go for it.
