I have an 87 rx 7 which is naturally aspirated. Where can I get a rebuild kit for the motor? The apex seals are toast.

 

Rotary Aviation master rebuild kit- $869. That's the only one I have experience with, so I can verify it's a good kit...If ya got the bucks, go with new rotor housings, about $500 each. I had 186,000 on my NA when I rebuilt, not only were the apex seals pretty shot, the housings looked like $hit too...
