the vzb v-spec is black, is it a VZR that is silver with the different head?

O.S. 21VZ-B (P) Rear Exhaust w/20L with revised Carbi.

Pretty sure thats what it is but with a later model carbi on it.
More then likely an onroad engine.
Probably one of their first revisions looking at the ribbing on the lower crank case.

The VZ-b is the predecessor to the V-spec. They are very similar internally. The VZ-b has a standard head button (not turbo plug) and slightly different timing. They are so close that the internal parts are all interchangeable.

OS off road engines always have a "b" in their name and the on road engines are always "r". A VZ-b is an off road engine, the VZ-r is the on road model.
