Switching Cas Cam Drives? Possible?

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

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?

im going to get my workshop to see if it works. Im fully detailing and polishing my engine so want to swap to the metal 33 and polish it too.. That plastic 34 cas just looks crap

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?

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
