ITR and Spec R are the same.
They just come from different sides of the pond.
You have a JDM B18c motor, which is a Sir-G. If you want to get more parts for it, you will be ordering parts for a USDM GSR motor. Its all the same. The main difference will be the intake manifold. It has to be GSR/Sir-G (p72) head specific.
The ITR and Spec R both use the PR3 casting which is the same as the B16a/B17a head.
