for a max of 25 psi well its going to be 20-21 put you never know...

 

stock seals, RA seals, 3mm seals, everyone out there has a different opinion. If I were you I'd go look in the Single Turbo forum for the guys running the type of power you want, see what they're using, talk to them, then make an informed decision. It's all opinion though, no one makes "the best" apex seals

 

NRS 1-piece 3mm gray seals

i got them and love them

 

Stock Mazda seals.

 

^word. the best.

:AA:

 

RA seals if you dont want to blow your motor.

 

I love my OEM's... They're just right as... hardness goes. As stated everyone has their opinions. I guess what you'll end up getting is what your builder recommends and there's nothing wrong with that! The best thing to do is stick with something that you have experience with...

 

the best. i used them in my for 13 months now still going strong. the genuine ceramic apex seals will hold 6x more than the stock mazda ones but be careful and make sure there legit before you try it

 

i used the RA super seals. supposedly none have ever broken....

 

Alot of assies Swear by SCR seals..

but i never see americans using them much

always wondered why that is

 

As long as you stay (FAR) away from Hurley apex seals, you can't go wrong.

I've had good experiences with the oem 2 piece seals, and just about every engine I've built has had oem 2mm or 3mm seals in them.

I don't have any personal experience with the RAs, but if Jason has installed that many sets with no problems, it's certainly something to consider.

Davin, you love those NRS seals with zero miles on them ?
