Switching Cas Cam Drives? Possible?

[syncade]

I was wondering if anyone had tried this procedure already. My R34 Rb25det Neo has a dead CAS (was damaged during shipping). I know the Hitachi cas from the neo's has a different cam drive than the Misubishi cas's (s1 and s2). I have access to a s1 rb25det cas, so I plan on taking them both apart and putting the cam drive from the neo cas into the s1 cas. This would make it connect to my exhaust camshaft perfectly, in theory.

Has anyone actually done this, or know for a FACT if it will work or not?

I appreciate the help gents! Not much info on these motors over in my country, and even less knowledgable poeple!

And yes i did search lol

Although i have never done it, im led to believe it can be done fairly easily.

you'll note on the shaft of the cas(mitzi) there is a hardend steel pin that holds the keyway on, punch these out and swap them, ensure you dismantle it so not to shock the components before punching the pin out.

Does the hitachi have this pin also?

Yeah my friend actually tried it with a Z32 300zx CAS (supposed to be the same as RB), but it did not work. Maybe he just gave up too fast?
