ITR/CTR piston ques??
 

if runnin itr/ctr pistons on a b18a1 will i need to run over 93 octane??or would 93 be fine?

93 will be fine, its all about how u tune is when u should be worried about octane levles, what head are u using, CTR pistons are very aggressive, clay ur head b4 you run it to ake sure u have proper clearences

the head im going to be using will be a b16 pretty much going lsvtec but im taking my time to get all the neccesary pieces to build it right the 1st time

running itr pistons will be fine

i believe that running the ctr pistons puts compression up around 11.8-12.2:1 depending on the headgasket, spec of the head, etc.

i think it would be safe to run the itr pistons b/c ive been told by several people you should run slightly higher octane on cars over 12:1

u might have a problem with clearence with the CTR;s Itrs would be good tho...check honda-tech for this stuff way better then TRi...just rember search on H-t dnt post haha
