Thumbs up Engine Rebuild Delima

Ok, recently bought an 88 n/a engine runs, idles fine, but coolant is burning so oil control ring. I plan on keeping it n/a.

I don't mind breaking the engine open and rebuilding myself.

The delima begins...

350 basic rebuild kit no apex seals
700 is for rebuild kit w/ seals
900 replace everything but block and rotors
1800 rebuilt engine w/ 3 year unlimited miles.

Which would you choose and why?

Where are you getting that quote for 1800 on the rebuild? Must be just soft and hard seals replaced only since housings themselves run $1000 but still a fair price....

All soft seals get replaced regardless.... Hard seals get inspected and replaced as necessary unless you are OCD.... Engine block componenets always have a chance of getting replaced, especially housings if worn out of spec....

The difference between the 700 and 900 option, I don't see what the difference is from your post they sound like the same thing.

IF you already have all the tools, tear the engine up I would say and save $800-900. If the housings and side plates look good all you have to do is replace the seals ($700-900 according to you). You will end up with the same "rebuilt" engine that runs 1800 minus the warranty.

Otherwise if you have to buy the tools, don't even think about it and just get the rebuilt with the warranty. Fair price....

The rebuild kits that I've been looking at were all atkins rotary.
I believe I have all of the tools already I would guess.
If there is a better place to get rebuild kits for cheaper, and the same quality I'm game. Everyone I have talked to says atkins rotary is the way to go.

Well do double check. I am speaking of specialty tools like micrometers, vernier calipers, dial indicators, rotary engine stand adapter, ect.

You will be needing these to measure the engine components to see if they are within specifications. The cost of these can be quite high which is why I recommend if you don't have these spend some money on the already rebuilt engine unless you plan on rebuilding more engines in the future (which is when they start to pay for themselves). Otherwise if you already have these tools you should be knowledgeable enough to sucessfully rebuild your own engine and save $800.

Atkins rotary and these companies have rebuild kits, there may be more but these are the :
http://www.rotaryaviation.com/
http://www.banzai-racing.com/
http://mazdatrix.com/

Don't forget to get a rebuild DVD from rotary aviation or mazdatrix and the factory service manual. These will be your best friends.
