Ok me and some friends are in the process of building 3 12As...





We are going to use the Mazda factory gaskets...BUT the apex seals im thinking to use aftermarket ones..



What 3mm apex seals do you guys recoomend..and why...



I plan on going boost and should I stay with the Mazda apex seals and springs?



What do u think about the sideseal...the other engines will just be street ported..no Nawwwzzz or boost

 

Well, I know PFS recommended all Mazda OEM to me. I trust him!

 

PFS?



Im going OEM on all besides apex seals..



Anyother advice?
