Does 91 CAS work in a 90?

[onegee]

Im getting a motor from a 91 and putting it in my 90. Using my TB and associated sensors, as well as knock sensor and o2. Question i have though is that will I need to switch out my 90 cas with the 91?

Also after install if i switched them, i would need to reset my ignition timing right? plz chime in if you have experience and have done it before.

yes, you will need to retain your 90 CAS.

And yes, you will need to adjust your timing.
