im considering going high compression turbo. how do you think these seals will stand?

Seals = Go

Springs = No, unless theyd fix the flattening issue

Use the factory OEM 2 piece seal. It's far more superior than the RA seals.

I second win911. My favorite is OEM seals cryo treated with OEM cryo treated springs. Falken RX-7 has been running them 3 years now at 24-30psi of boost. Or ceramics if you roll like that. https://www.nopistons.com/forums/pub...#>/biggrin.gif

i ran RA seals on a S5 T2 motor with S5 na rotors detonated several times and never chipped or cracked any of the seals,motor was taking apart around 5k and i did not have any scratches or abnormal wear on the housings,now the motor was always ran on heavy premix plus using the stock OMP sistem

I vote no to RA seals. Bad idea, IMO.

Ive had good experiences with the RA seals, but apparently I am one of the few. Bottom line is Mazda has decades of research into finding a nice balance between a durable seal and one that is kind to rotor housings. Its easy to make a tougher seal for cheaper, but dont expect it to work as well all around as Mazda seals.
