Look in the workshop manual. That book tells you how to do everything you could ever want to do (a complete Rx7 rebuild)
I believe it (the manual) can be found online in PDF format if you look around, something maybe www.iluvmyrx7.com had it.
The section you are looking for is "S" if i remember correctly.
