getting my first fc
 
i recently checked out a 88 fc. Its very clean body and really nice interior, normally i work with american cars or normal engines. I never worked on a rotarty or have any experience with them. a few questions i have are
how many miles for this car b4 rebuild time? currently its 128000
and how hard is it to rebuild?

No single answer to the "when is it time to rebuild?" question. Some things to consider.
Did previous owners take care of the car the way rotaries need to be taken care of. What I mean here, was oil changed every 3000 mile or so? Was the car ever overheated? Did previous owners know to redline every week or so?
A good indicator would be a compression check on all faces of both rotors. Readings should be at least 90. 80 or below and you're looking at a rebuild.

Rebuilding a rotary engine can be done . The factory service manual will help a lot as would access to compressed air and a reasonably well stocked garage.

Well cared for rotaries will go for near 200K without needing a rebuild. Poorly cared for cars will crap out after 100K, so knowing this cars history at 128K is important.

thanks for the info the car does not look like it was abused, it seems like it was well cared for but i dont know the history except it should of been 1 owner

y would i need to redline everyweek? and what rpm? what gear? what speed?
soundsbad to redline, nvr redlined my stang but hey it aint a rotary.

You need to redline because carbon deposits build up where they shouldn't...redlining helps to clean it out, so that your engine doesn't lock. It's not quite as bad to redline a Rotary as it is to redline your 'stang. I redline my N/A RX-7 every few days, just to be positive...

any info on when 2 redline? what rpms? what gear? speed? just dont want 2 mess up my engine as i cant afford to really fix it

False.

yis it flase? and if so whats the truth? thanks for the useless post

"thanks for the useless post"????? we tend to be a bit nicer to people around here. thank you have a nice day!

Rathmar 11-06-06 10:10 PM

That makes 2 useless posts.

it shouldn't matter what gear or speed you redline in aslong as you wind it up.

however the carbon desposits are not the result of not redlining the car. one cause of the carbon desposits is from the oil injected into the engine to lube the seals, this is especially the case with certain types of synthetic oils. Like recommended above do a compression check on each rotor face and this will shed some light on how much life is left in the engine. Also, if the engine turns over I wouldn't worry too much about carbon desposits anyways.
