1989 Mazda rx-7 Turbo - Engine Overview

Does anyone know where I can get a complete engine overview or a complete parts list and how-to. I dont know much about the engine. Everything in it is stock but things have been stripped out and disconnected so if it is at all possible to get some sort of guide, that'd be awesome.

I have another question. I dont even know what an idle box looks like or the egr valve on this looks like because I believe its missing and wont pass smog without it.


Thanks.

get a factory manual,
or a haynes, but the factory service manual is much better.

yea im stupid i dont know why i didnt think of that.

There is no EGR on series 5 ('89-'91) RX-7's.
