Ceramic Seals at Discount
SOLD! Thanks.
I have one set of Iannetti Ceramic seals that I need to sell cheaper than normal. The retail price for Mazda Competition Parts is $2700. My cost is close to $2000.
These are the ULTIMATE seals for the renesis and I recommend them for anyone who wants to make the most power over the longest period. In street usage these should outlast the car or literally not wear out in decades. The beauty of these is that they do not cause the normal wear to the apex grooves of the rotor and are unusually easy on the rotor housing surface due to their inherent lubricity. This same lubricious nature allow these to be used with higher spring pressures permitting better sealing at high revs as well as improved torque in the mid range. They are resistant to warpage or deformation brought about by high temperatures or even great temperature variation.
Although these seals are much stronger than the stock steel seals I don't recommend them to people using forced induction unless they have mastered their tune. These are not for the experimenting crowd. These are the choice seal of racers in the Star Mazda series and the Koni Challenge especially since they can be used over and over and over again.
Iannetti is the ONLY brand that we have used since 1990 other than stock OEM.
They can be purchased here for $1975: http://www.mazmart.com/PartsList.aspx?id=29&n=NEW&m=6

Rotary , eh?

Not sure I would trust the Mazda cast to be deep enough in extreme load situations. There doesn't appear to be much extra material there after making the change in the machining. Of course, it's pretty hard to measure that area without having done a CMM. Just sayin'.

When I was thinking about doing 3mm Ceramics myself; after talking to a bunch of folks it seemed that 1 out of 4 rotors would crack after warm up/break in due to material loss and the motor would have to be torn down and a new rotor installed....a 25% chance of failure-IMO not worth it.
However the FD sized seals seemed to work fine; just have a good shop machine them.

Paul, I'm curious what your thoughts are as to the best option for seals for a boosted Renny motor. I've got a motor being worked on by Brian at BDC, but I'm a bit stumped on ideas for the seals. Suggestions? I ask here because I notice that both you and Racing Beat do not recommend ceramic seals for boosted motors and I'm curious why not?

1)They're hella expensive.
2)Though, they are more resistant to detonation, they are not invincible.
3)Get your tune right BEFORE you buy them, because if you don't, it's an expensive mistake.
4)They'll last nearly forever on a renesis with a perfect tune due to great lubricative nature and lack of wear + they will not damage other engine components, so its a great choice for a stable engine. Newly FI'ed engine with a less than perfect tune is NOT stable enough to stay detonation free.
Anyone correct me if I'm wrong- Don't claim to be an expert

I'll try to PM you what approach I recommend in better detail.

From what I've seen and through my limited knowledge I'd say:
1)They're hella expensive.
2)Though, they are more resistant to detonation, they are not invincible.
3)Get your tune right BEFORE you buy them, because if you don't, it's an expensive mistake.
4)They'll last nearly forever on a renesis with a perfect tune due to great lubricative nature and lack of wear + they will not damage other engine components, so its a great choice for a stable engine. Newly FI'ed engine with a less than perfect tune is NOT stable enough to stay detonation free.

What I find interesting is that - everyone agree's they are at LEAST as detonation resistant as a metal seal; so why are they are not recommended for FI?
If cost is the issue - then simply say that they are expensive.... but a renesis seal failing can cause plenty of extra damage all on it's own...

i would say that Paul is referring to a cost benefit type of thing? Boosted renasis engine have a way of not lasting 100K. Probaly because we mostly are idiots just having fun--self being a one of the 1st club members.
I wish they had ceramic side seals.
Oh by the way Paul just spoke with S --in need for a trans and to make sure I was one of the 1st on the list for the oil bypass mod.
Have you seen the results coming from converting our cars to a single oil cooler? Nice results --you should look. I see an entire kit???
