exactly as stated above... what cr will ctr pistons make my gsr? is it do-able or am i kidding myself? As for c/r's would 12.0:1 or 12.5:1 be streetable with a good tune and 92 octane? sorry for the ???'s but i am currentlt boosted and know nothing about high compression allmotor. any help would eb great. thnx

 

ctr pistons on a gsr make a ton of compression. I read that big *** post at the top of the page about CTR pistons and i dont member exactly what the compression was but it was definatly at least high 12s if not 13s. I wouldnt think they are streetable but im new to this **** so dont take my word for it. But one thing i know for sure you wouldnt want those if you have a turbo.

 

THANKS FOR THE INFO BRO. I AM SELLING MY ALL MY TURBO **** THO. ITS JUST TOO MUCH HASSLE TO DEAL WIT. KNOW WHAT IM SAYIN?

 

go to c-speedracing to calculate your compression
