Cas Differences

[Conrad 2NR]

I'm looking to find a replacement for my CAS in my RB25DET SII. I've used the search and looking at them I'm still left a little confused and would like a 100% sure answer before going to my contact for a replacement.

Now the guy I'm supposed to check for my replacement says he has a number of RB CAS' but he's not sure from which motors they're from (either RB20/25 or 26). What I would like to know, short of removing my CAS and walking with it, is their anyway to identifying which CAS would work in the SII?

All the later CAS's are the same up til R34

The only one you will have to be careful on is the early R32 version. It has a rectangle plug on it. The Rb20, 25 and 26 CAS in the 91- models has a rectangle plug but too but the corners are rounded.

They are made by Mitsubishi and try to get the one with the black rubber plug in the centre as they are usually all later model ones

Thanks alot for the quick reply.

I'm going with the car to pick up the CAS, so basically what you're saying is:

1) Look for one that fits the plug (it's easy to unplug rather than remove the entire thing).

2) Ensure it also has a rubber plug in the centre?

Yep

As long as it plugs in and it's off an RB, the CAS's are no different

Thanks a lot! If I were in Australia I would get you a beer.

No problem mate, that's what we're here for

oh btw one other thing. I have never tried to plug an R34 CAS into an R33 loom so it may plug in also. An R34 CAS can easily be identified by it's black plastic body, rather than the aluminium one in previous models. It also has a different cam drive.

RB20 Red tops - just for interests sake - had 3 different CAS.

Two by Mitsu, 1 by Hitachi

I will be doing the opposite - R33 cas into R34 ecu - apparently it just requires the reversing of some wires.
