S4 T2 alternator upgrade
i have been told that this is a quick and easy bolt on upgrade. they also say that the S4 T2 alternator shares the same connections where the S5 connections are different. my question is, how can you tell if its a S4 T2 alternator? can someone tell me what i need to look for? are there any serial numbers that i need to pay attention to? thanks in advance...:dunno:

Any S4, (86-88), alt is a direct bolt on and go.

alt
The alt will bolt right on the mount with no problems. You have to wire it diferently, (there is a thread for the proper way on the archive).

Ok, now I'm worried, I bought this alt. off ebay. Supposed to be a "bolt on and go" 80 amp from a gen 2. The plug is different than my 84, which is ok. But I've got 300.00 + invested in a belt drive system and don't want a sloppy shim job to make it work. I've already used a brass brush on it and painted and mounted my pulley. Is this alt a direct fit? Sorry if this seems stupid, but it was one of my first purchases, and I am going to begin assembly Mon. I thought I did my homework, but you all know better than I.

Ok, googled the rx7 alts. and found mine. It's off of a 91 turbo. I'm sorry, but i don't have the alphabet soup memorized yet, so I'm not sure if that makes it an S4, S5 or what. ........ I'll exercise the search button and find out.
Thanks for the quick write up Sgt.Fox. |
I am fairly certain that the connector being on the side instead of the back is a trait of 3rd gen alternators.

91 n/a alt?

wait, s4 alternators are considered an upgrade on 1st gens? Those things suck

Diagram is using the alternator pictures from the first and third gen factory service manuals. The plug on the S5 is the same as the S6.
