If you stay around 600whp or less and 550 ft/lbs/tq you should be fine for a long time. Just make sure the kit is installed right and you use a top tier tuner. Tuning is everything!!!

46-48 psi... WTF, my 11:1 SB350 was something like 150 if I remember right. I would thing we should be over that since we have higher compression. Never checked my 370Z but maybe it's something with the cams or the VVEL?
