Yeah, all the experts in here really fell up the board. So now I learn new thing, by using p30 pistons, I wont be able to use my stock rods. Will, if I find a set of P30(does it matter what year they came from, as long as its a p30?) I will buy after market rods or ITR rods. So, if I do buy a p30 piston set, which honda motor pistons rings would fit? Where did Bill purchased his from?The reason I havent decided which pistons to go is that I dont want any compression higher than 12. Some of you guys have different opinion, and suggest different brands. I check Wiesco, they have something like 11.8-12.4 I will give them a call to see if they have a set that will meet my need. I will also check on IB after finishing typing this. and if Wiesco accurately claim that the 11.8 is true, then I think I will go with them and look no further. thanks you guys for all the helps AND KEEP POSTING SO I can ADSORB ALL OF YOUR SKILLS!
