b18c1 block, ITR p73-00 pistons

some shops have said to me with honda internal parts, there is no need to re-balance the crank, but i believe balancing is needed to be done.

anyone?

 

honda cranks are generally well balanced items i usually never touch them from factory but the piston and rod weights should always be double checked on a precision scale...

 

if u really want to balance ur crank u can send it to laskey racing and have them balance it for $150 shipped to and back to u

 

so for the question, is balancing needed? im using the gsr rods(shot peened) and new bolts(arp). i kno a lot of people ran that set up, and i would like to know if they balanced it or not.

 

The JDM ITR .25OS pistons I bought were pretty well matched. Two were 319g and the other two were 320g.

The CTR pistons were a different story. I've measured a couple of sets and they were anywhere at or between 330 to 335 grams.
