2mm or 3mm seals?
I am in the middle of doing a TII conversion on my Na Rx7. and while the motor is out i am having it rebuilt and having a stage III street port done on it. i am also doing a T66 turbo upgrade and thats all i can tell you without letting the cat out of the bag. i am in the middle of a debate that has me baffeled. I need to decide if i wanna go with 2mm cryo-hardened seals or 3mm cryo-hardened seals. or should i go for the aviation seals. i am plannin on pushing 15-20 psi.
As far as the seals go i am clueless. i have heard that the 3mm seals dont seal as well as the 2mm seals, and the 3mm arnt good for daily drivng.
Any and all advice or comments welcome.
Thanks TurboSmoke

it pretty much says that you dont need 3mm unless you wanna spend the extra money. all that 3mm seals do it help protect detonation only by a little bit. but as long as you are getting your car tuned by a professional then you shouldnt need 3mm seals. i would go with 2mm. Also they should be used if your apex grooves are worn out so that 3mm will fit in there so you dont need to get them machined out to much.
Read that thread though, tons of info in there
