ITRCA

I am in the process of building my motor right now for more boost and am going to need a new crank. Is there a difference between the GSR crank and the ITR crank?

If so, what are they?

Would there be a difference in running a ITR crank vs a GSR crank in a built motor?

Thanks

If you must switch cranks, I would recommend going with an LS. It has a longer stroke (89mm) vs. 87.2mm of the ITR/GS-R.

The ITR has more weights to evenly balance it versus the GSR. It's supposed to make the crank run smoother at high RPMs.
