OK. WHATS THE BEST APEX SEAL.2MM,3MM,1PC,2PC,3PC,STOCK,HURLEY,ATKINS,ETC, AND IS CERAMIC REALLY ALOT STRONGER THAN STEEL.MAINLY IM LOOKING FOR STRENGTH AND RPM(9500)+ ABOUT 20PSI(T4).AND DONT GIVE ME BS ABOUTAIR/FUEL RATIO.I ALREADY BLEW 2 SEALS(STOCK/110,000 MILES) WITH AN E6K RUNNING PLENTY RICH.ALSO,DOES ANYONE KNOW OR HAVE TRIED WHAT MODIFICATION HURLEY DOES TO THEIR ROTORS TO USE OIL INSIDE THE ROTOR INSTEAD OF USING MOP OR PREMIX(SPECIFIC.I KNOW THEY DRILL THEM.)

carbon apex seals found here

Under normal driving/racing conditions, including NOS, turbo and SCs, many people have said that 2mm seals and 3mm seals are no different, as well as 2pc and 3pc seals not having a difference either.

On the same page as the carbon seals are the ceramic seals, costing $297.98 each, requiring over $1800 for a set of 6 to do both rotors.

As far as the oil question, I have browsed through the Hurley web site, but don't know much about their mods. I do know that a company who makes rotary engines tailored to aviation use has come up with a mod (compatible with RX-7 rotary use) to get the oil metering pump to pump premix out of a tank instead of pumping engine oil in the traditional manor that it does. Click here to go to that page. It doesn't explain in great detail how their mod works, but if you purchase the part it comes with instructions. Also the page has an email address if you wish to contact them. Basically, the mod allows you to run the stock metering pump, but it is supplied with 2 stroke oil, or what ever premix solution you choose. Instead of having to mix it in with the fuel every time you gas up, it is in a tank. (that you must supply, tank doesn't come with adapter mod) A simple bit of home engineering, and you can even hook up a tank level sensor so you don't ever have to pop the hood to check it. if I do decide to purchase this mod, I will use something like an oil pan oil level sensor and wire it into a light on the dash so I know when the tank is low.

Anyway check it out and see what you think. And one more thing, the CAPS LOCK key can be found on the right side of your keyboard

i've read the 2 pc (and 1 pc)are stronger,and that the ceramic lasts alot longer than steel.but why would the factory use 3 pc instead of 2 pc.

I don't know why factory used 3pc seals. 1 pc seals would have been nice.

1) Why are you spinning that high?

2) You realize running overly rich can also blow your engine?
