Haven't done it yet, but im in the process of swapping an 85re into a 81. Yes it needs to be reffed. 1-800-622-7733 is the number to contact the Smog Ref in your area, you will talk to a random person on the phone, if they cant answer they will leave a message with your local ref to call you. The fresno ref seems real nice.
