are they all the same type. for example if i were to replace them, would i buy 4 of the same type? thanks by the way

The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.

But the short answer is that they are the same size. 460CC for NA, 550CC for TII.

thanks again for your help i'll be sure to go and try to purchase the haynes service manual

Yep, if they dont carry it at the local auto parts store, they can at least order it. Its a great investment.

yes all 4 of them are the same but all rx7 injecters are not the same tII had larger ones

Haynes Manuals can be found easy on ebay.
