apex seals
ok so i know that fd and fc seals will swap... depending on 3mm or 2mm i havent got my engine torn down yet but i know the apex seals arent making compression. i have the chance to buy some apex seals for a really good deal but they are 3mm.. is there anyway to tell what size i could use ?

All 86-95 rotary engines use 2mm seals stock. There is no difference in the seals between those years, they are all the same 2mm 2pc version from mazda now. The only thing they changed in the FD engine were the corner seal springs, which are a recommended upgrade for an FC during any rebuild and don't cost more than about $30.
Now, if the engine has been previously rebuilt, then there is no telling what you have, you will just have to wait until you get inside to find out.

Also, do not use the 3MM seals. You will spend more money making them fit that you will save buy getting the seals. Also, they really aren't as good as 2mm seals. They are slightly more resistant to detonation, but they don't seal as well.
Do not EVER under ANY circumstances cheap out on a rebuild. It will do nothing but cost you way more money down the road. Apex seals cost about $220 for a whole set at www.atkinsrotary.com Compared to the cost of a while rebuild, its really not that much.
The bottom like is that if you can't afford proper apex seals, then you can't afford a rebuild. Period.
Also, make sure you replace all of the springs with new ones.
