just basic maintenance of any car, change the fluids religiously

What bout the Apex seals do they have to be changed as often as in the FD's?

I about to hit 139k on my original motor with no major problems. I think the 2nd gen's are a little more trust worthy if you ask me. Just my opinion though, I wouldn't mind having a 3rd gen.

I wouldnt mind having a 3rd gen either i dont think anyone would. Hopefully ill be able to afford that car but if not then im getting and FC, btw how hard do you drive the car?

ooooooooooooold rotaries (i think 60s and early early 70s) gave rotaries a bad name in reliability, and then FDs being improperly taken care of resurected that again.
turbos are the unreliable ones nowadays, both Turbo II's and FD's can kill apex seals, breaking seals is caused by leaning out most times (too high of an air to fuel mixture, rich is too much fuel and that kills sparkplugs, lean is too much air and that kills apex seals at a certain point)
actually, the leaning causes predetonation which kills the apex seals
anywho, you change seals if you're rebuilding the engine.

So if i turboed the FC the seals would need to be replaced more often? Cant i get some $1000 seals that last for a long *** time?

Yes, but why bother? It's cheaper to rebuild with a $300 set of seals six times than it is to rebuild with a $1800 set of seals once. Besides, detonate and any seal will break, and when the ceramic seals break it's not as pretty

In my humble opinion the general best are mazda STOCK 2mm 3 piece, there are some better, but these are stock, and work GREAT.
Seal price does not matter, a seal is a seal and it WILL break
