See those are the kind of results that i was promised from my honda tech. I am not too smart in these kind of areas but the baseline copression ratio of the GSR is about 10 and if the new pistons were to raise it to a full 12.04 now wouldn't that give a nice little boost. Now i dont need a lecture about my ethics and my thoughts all i need is advice. Is it a good idea, i can get the pistons 180 shipped, plus 70 for installation. 250 bucks for an increase in the 5-15 range in HP. Is that not a good investment. Yes i plan on getting performance cams and cam gears also. :naughty:
