Looking on RX-7 store.com I saw that a Mazda Reman is $2300. Seems resonable my only question is what do you guys think the ratio of how much engine remans should be from regular piston engines to rotary. Knowing that Wankel engines are not your every day engine, if it was as common as your piston engine wouldnt you think reman prices could possibly be lower. Wankel engines are more simple and to my knowlege less moving parts and what seems to be a simple easy to make design (once again to my knowlege, im no expert). Now all you FD guys out there, on rx-7store you send in your engine bla bla bla, is there a cheaper way to rebuild a engine without such high prices by keeping your original core.

Yes, there is a cheaper way. You can just get a rebuild kit and replace all the parts that are affected by wear, i.e. the seals. But many times there is wear on the rotors and or housings, so they need to be replaced, which is why many people just assume that they'll need to be replaced, and get a reman as kind of a "fresh start"

Well, just the seals+gaskets you will need cost several hundred dollars. And then you have to send out for things like getting the housings lapped, etc. This assumes your housings are reusable, many times one or both rotor housings are not. Mazda charges $500 for each rotor housing.

Yes, you can rebuild a motor for less than the cost of a reman, if you do it yourself or have someone else do a shitty rebuild...
