on t-25, 14b, and dsm manifolds there is a ridge that needs to be ported away for smooth flow. Along with that the hole is opened to 7cm as well as the manifold.
Along with that coating both the manifold and the turbo hot side with ceramic will help your under hood temps as well as extending the life of the turbo and the vital parts on your motor
turbo port- $50
manifold port - $35
dsm o2 housing ported to 2.5 or 3 inch - $45
Ceramic coating turbo - $100
Ceramic coating manifold - $100
Ceramic coating o2 housing - $75
Ceramic coating a downpipe - $250
I already have some ported 14b housings in stock, if you would wish to buy them there is a $15 core cost that will be returned to you when i get your good hot side back.
I also have copper turbo gasgets with rings for better seal.
mitsu, t3, and t4 - $17
