any difference between GSR and ITR rods?

 

nope none at all

 

the only difference is if you mean the 92-93 gs-r's the rods are shorter for the b17, but for the DC integra's gsr's have the same rods as type r's

 

thanks

There is a difference-but you can use either in a B18C.

But is the difference real?

 

ITR rods are supposed to have a higher chromoly content.

Type-R rods have"R" stamped on them, so they must be better

 

ITR rods use a different big-end numbering system (22 to 25 instead of 1 to 4). The rod fasteners are the primary difference tho. The regular P72 rod fasteners don't have the dimples on the ends for a stretch gauge.

The masses are very comparable. The range of mass is from 544g to 553g. However, the rods are typically around 545g to 547g in the matched sets I've sampled.

I'm also inclined to say that the ITR rods' big-ends are finished to a larger bore, but I've never had a chance to sample a large number of both types of rods. My basis is that there's an extra step on the number system (5 for ITR vs. 4 for GS-R), and that the ITR's are spec'd to run .0002" looser on the rod oil clearances.

 

"Connecting Rod Summary:

* Connecting rod bolt elongation has been strictly controlled for uniform fastening force
* Manually assembled for the Type R to reduce fastening force variance
* The specially designed rods have the letter "R" molded onto them
* Rods are constructed of special high-strength steel to withstand higher rpm's and are still lighter than GS-R connecting rods "

Vinny, showing up with some knowledge.

 

haha you know it!

pretty cool link i found about the ITR.
