From what i can see, they're Nippon Racing Low-comps. I am guessing you're running boost, so i would say this isnt the best piston for you to use. At low psi you will be ok, but they are cast pistons, and any detonation will shatter them. Forged is best for high-HP.

 

save up $300 more and buy the mahle's. they are probably the best buy in forged right now and you can get a nice flat top that's just under 10:5-1 on a gsr head or about 10:1 on a pr3 head for $450 shipped. i THINK a super low comp is available too if all you do is drag race. some 8:8-1 motor is a lazy street car though

 

Yea, Mahle's kick ***, i run them.
