i bought these rods and was told they are oem itr rods, but im not sure if they really are. i took some pics next to a old gsr rod i had around and they look pretty much the same. i thought itr rods where p73's but these do have the r stamped on them so i dont know. another thing is the "23" on the side, it looks like its on with ink or something and i thought oem honda rods were engraved, these are not.

someone help me out here...





supposed "R" rods are on the right if you cant tell.

call me **** but im trying to build my motor with all oem itr stuff.

 

Yes, the ones on the right are oem itr rods. They are almost identical to gsr just by comparing the way they look.

 

Rod fasteners don't have the dimples to facilitate the use of a stretch gauge on P72 rods. Big-end bore sizing schemes are labeled differently, using 22 to 25 (ITR) instead of 1 to 4 (P72).

The masses are roughly the same between P72 and R rods, as are the mass groupings for a matched set. Individual rods can be anywhere from 543 grams to 550 grams (from what I've seen in about 5 different sets of rods). Matched sets are typically have no more than 2 grams of difference between any two rods.

I've never measured center-to-center rod lengths for any of these rods, so I have no info on how consistent or how out of specification they are.
