Bare with me guys if i dont make sence i just woke up about 2 min ago... Well i bought my first rx7 about 2 weeks ago for $900, I knew it was going to need to some work so i expected something like this to happen. The oil control rings need to be replaced, so im thinking im just going to do a total rebuild. What im stuck on is should i just go all out and buy a rebuilt engine for $1700 or should i just get the rebuild kit from atkins rotary for $900??? When i bought the car it didnt have any type of radiator fan at all so if i wasnt driving the car would start to overheat.... could this have caused any warpage of or permanent damage to my rotors or rotor housings? im a newb to rotary's, and ive caught the bug. Also i have close to 2k to spend on this project.

well this is the site that im looking at www.atkinsrotary.com

If you're not too familiar with the rotary engine I'd say get the rebuilt engine.
That way you can just swap it in and not risk having to take it down and apart again because you made a mistake when rebuilding.
Besides, you'll have the bad engine and the good engine,so you'll have spare parts which you can sell or later on down the road,when you're more familiar with the engine, rebuild and port the engine yourself.

Well if you did not run the car into the upper(overheat) range of the gauge then you probably did no damage to the components. How do you know the oil control rings are bad?

As far as rebuilding goes. You can do the rebuild yourself if you have the area to rebuild it, the proper tools to spec it out . And feel comfortable doing it. Of course if you buy a rebuild thru Atkins then you not only get a great rebuilt motor but it comes with a warranty. By the time you buy the rebuild kit and the needed tools you could easily be up to the $1300.00 range.

Correction, he will need to turn the old motor in for the core value.

I was under the impression he was only buying the rebuild kit from atkins, not the engine aswell.

my bad.

I recently had to make the exact same decision. I opted to rebuild it at home, given that I have some experience building engines and especially that I DIDN'T really have the 2grand that a good motor woud cost. One thing to watch out for- many motors may seem to only have something simple wrong with them, but then turn out to be bad cores. I went through 3 core-rotaries (including the one out of the car) looking for good parts and still ended up buying a set of new housings. On the rotors, the bearings and stationary gears can go bad. On the rotor housings, the chrome coating flakes and you lose compression. On the intermediate plates, the friction surfaces might be scored or warped. I would say that rebuilding at home is still a good option, but only if you are ready for potential setbacks like these. As with any major project, expect it to take twice as long and cost twice as much- that way you have at least some preperation when the unexpected turns out to be the case.
