How do i know what RB25 I have?

[John Bristot]

The title says it. How do I find out what kind of RB25 I have? Tell me if you need me to post pics.

there is lots of info on this if you search for it

[John Bristot]

Well if you would give me the correct way of telling the search engine what to look for maybe I could. I always search before I ask a question because then I get some person saying, Uh use the search button, flame.

on the back of the coil cover you'll see an igniter chip mounted there, if you dont and you only have 4 mounting stud there then u have a series 2

Thank you.

And if you have a black CAS (thing on the front of the motor connected to the exhaust cam) you have a late Series II.

Early series II has a silver CAS like series I motors do.
