MS Rebuilt rotaries?

Hi guys.

I was wondering if anyone had any experience in buying a rebuilt rotary from one of the places that sell them online, like Gearheads, RX-7 World, or Atkins.

The main reason I'm wondering is because I live in MS and there are no rotary specialists around here that I've found. I just bought my 1985 GS with 99k on the clock. I've heard mix reviews as to how long these motors want to run before needing apex seals replaced, and I'd like to start fresh.

I called Gearheads and they quoted me approximately $2,100–2,400 for a 12a or 13b. RX-7 World has a much more inexpensive option, but I don't fully understand why it's so much cheaper (approximately $1,100 for a basic rebuilt motor).

Any info or advice would be appreciated.

Stick with the larger names in the Rebuilding world..

The reason why some are cheaper then others is because the probably use some of the old parts, you "CAN" us the old Side Seals, Corner Seals, ect.

P.S. The latter 12A's had 3mm seals, you should be good for about 150-200K before the engine will go.

Proper maintinance is the key to rotary longevity. Changing oil and filter every 3k miles and NEVER overheating the engine are the 2 main ones. Read through the FAQs at the beginning of the 1st gen tech section and download a copy of the 85 FSM and carb manual from either of the following links.

I also recommend performing the 30/60k maintinance schedule listed in Section O of the FSM. This will bring the the car into tiptop shape and begin to familiarize you with your new car.

I get my rebuilding kits from Puerto Rico. They are a lot cheaper than the US.

Thanks for all the info guys. If anyone has anything to add, keep it coming.

My biggest worry came from all the people who were telling me that rotaries are much more delicate than piston engines (in a sense that some piston engines can be treated like complete ****, but will keep running forever, whereas a rotary must be maintained properly to last). I always religiously maintain my cars, and while I know most of the car's story from the last 99k, I can't be sure of everything, so that's why I wanted to know.

I'll probably end up driving it for a while longer while setting aside some cash for a properly rebuilt motor to put in later on.

If you take that good of care of your vehicles then a rebuild may be in a galaxy far far away. Well maintained 1st gen 13Bs have been known to go for 250k, 12As, 300k+.
