I am rebuilding this T2 motor for a conversion project and still don't know which apex seals to use. I have read about them here for about 3 weeks and am still confused. Should I go with Mazda 2mm or 3mm or RA or Atkins? SOme of what I have read say that aftermarket seals are a no no for high HP and others say they are just fine. How much more expensive are the Mazda seals?

I will be using a stand alone and water injection.

 

We have over 700hp in our drag car and have used Atkins for the longest time... If an Atkins seal should break it will not be as bad (And I mean barely anything happens and sometimes nothing happens to housing, rotor nor turbo) for the rotor nor rotor housing as with factory seals.
