13B replacement

Hi I recently became an owner of a 1988 SE RX7, Unfortunately the 13b engines apex seals are blown, so I need to replace it. I have an extra engine, but I have no clue how to remove or install the rotary because I have never done this before. I have searched all over google and Youtube but I cant find any video to help me do this project. If any of y'all know any tips or videos to help could you please link them. Thank y'all!

Pulling a rotory engine out of a RX7 is no different than pulling a engine out of any other car.

If you have never pulled an engine then I suggest you find a friend that has to help you, or pay a shop to do it.

The Factory Service Manuals for all years of RX-7 (and many other rotary cars) can be downloaded for free here: Foxed.ca - Mazda RX-7 Manuals . They contain all common service information and more, and are 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. The Haynes is a good quick reference covering 99% of questions, while the FSMs show complete and detailed procedures.

You're picking one of the best platforms to learn how to pull an engine on actually, in that an NA rotary is extremely simple to remove from an engine bay. I always joke about my FB that there are only 4 bolts holding the engine and transmission in the car itself, the rest of it is just peripherals. That is simple when compared to a 2.7 twin turbo Audi engine and transmission that I had a while back...talk about nightmares...

Best of luck with the engine pull, feel free to check back in if you run into any snags!
