yes it is the RS edition, hand modded, the comrod was checked w/ the STS comrod to make sure it matched. It is the MT12 RS....threaded shaft. We looked at the Mugen's comrod but it was longer than the STS one.....I don't quite know if this is supposed to be but yes, it was the same size... Thanks for your input.

I was told that the diff between the RS3 and the MT12RS was the crank shaft, threaded vs. SG. Just in case I am running less shims on this custom version, decreased from .06 to .03. For the moment it seems to be performing well....hope it maintains this performance.

Thanks again,
