well if ur gonna run JRSC soon u should not get the JDM ITR pistons. compression
is too high. USDM ITR pistons will be ok. standard bore. unless the shop can overbore ur cylinder walls then get overbored USDM ITR pistons.
what other mods do you have or plan on getting??

 

dont even get USDM ITR pistons...if your going to do any sort of forced induction...leave it at stock or LOWER the compression

 

Would the overbored pistons do much? I'm considering running crower 403's in my car. What exactly are the benefits to the overbored jdm itr pistons?
