Ok Lets Cut The Bull Shyt
 

whats the best apex seals out there and what kind of boost has those seals seen on and average basis.

I guess ceramic...but I'm a noob so I might be wrong???

Best to my knowledge are the Ianetti ceramic seals. Mucho dinero though.

Ive seen the stock 2mm hold around 15 to 18 psi. Any more and you may want to move to 3mm

define best. price? sealing? lightest wieght?

forget the kiddy boost im talking about 30 plus psi

ok very strange i dunno how i was posting in that screen name, something is fucked up here... o well yea ima be running 30 psi plus with NOS

In that case, since you will be rebuilding the motor so often, just stick with the Mazda 2mm or 3mm seals. The ceramics will shred your housings and turbo if they break -- more so than the Mazda seals.

o yea u think motor will break so easy then tell me why Abels 2 rotor was so strong, he blew sometimes but not like what u think he should of been, trust i have a beast coming up

I think if your wrenching skills are anything like your writing skills, you will probably be rebuilding your motor more than you think.:D

Pritty sad that we got someone in the forum that comes to learn grammer and speach instead of rotary talk and yes im talking to " U ", but to put it to you like this I do work on a street car that weighs 3600 lbs and ran a 9.20 at 157 on 28psi with a single fogger and a shitty 60 foot, and you call out my wrench skills, well if my wrench skills is like my mathematic skills that equals to a mid 8 sec street car, which equals to ummmm worlds fastest street car then yea i might be rebuilding my motor soon.

U must work on a supra or F body if it weighs 3600lbs in drag trim. :)

yes its a supra Albert Diaz's supra

I'm pretty sure there are some 7 sec. "street" (I use that term very loosely) camaros and mustangs out there. So the supra you're building wouldn't be the fastest street car. "No replacement for displacement."

Ok. And exactly how many miles do you think you're going to get out of a 30 psi T-88 13B running nitrous? It's got nothing to do with wrenching or tuning, that's asking a lot from an engine...

Exactly man, the reason were saying its going to rebuild often is even with amazing tuning the more boost the less life the engine more stress on the springs and seals. Also as someone mentioned go with the 2mm or 3 mm but not ceramic, those things break, and its bye bye housings + turbo.

when i say fastest street car i meant fastes import street car, but n e ways lets not fall of topic here, i do expect the motor to go, but not like every 3 or four races

if your worried about breaking ceramic seals you got other problems to worry about.
Any seal will break if the motor is not properly setup!

When you ask "which are the best seals out there?" pretty much everyone on the forum will start taking shots at you. There is no real answer to this question. Any rotary expert will tell you that it's not about what type of seals you use but it's the tuning. Just about any seal on the market will hold 30 psi if tuned properly. Supposedly the ceramic seals can take the most abuse before they break, but the point is, if they are tuned poorly then they will evenutally break just like any other seal. To answer your question, I have heard of people boosting at or near 30 psi with just about every seal out there including stock 2mm. Seals don't break because they can't handle the boost, they break because they can't handle the detonation, usually associated with boost.

What turbo will this be on? What type egt's are you planning on running? What type of fuel are we talking about? Do you have a a/f ratio in mind? How much of a shot will you be running with it if any?

sorry, double post

It was a joke. "U pritty ummmm got fogger U"

BTW, 9.20 is not a mid 8 second street car. It doesn't matter what the 60 foot is, it is still a 9.20 second car.:D

Why? If tuned properly the stock 2mm seals can easily handle more. They've been tested over 30 psi without failure, although you would be sitting on a hairline edge at that point IMHO.

And to reply to the original question, what is the best apex seal on the market?

1) If cost isn't an issue then definitely the Ianetti Ceramics, maybe even the new kid on the block NRS Ceramics which seem to be just as good.

2) If cost is an issue (and you want 2mm), then you can rule out ceramics, and go with the stock Mazda seals (the newer versions)

That car has already been in the eights.

IMHO since your going to be running so much boost and rebuilding from time to time, I would go with the aviation seals. From what I understand when they blow they warp and don't destroy the housings and turbos like some of the others. This could make future rebuilds alot less expensive.
