which gasket do i get

[sethtroy]

i just bought a ported o2 housing and i have a 14b turbo stock from my 1992 eclipse gsx and i am wondering what gasket do i get a 7cm or 6cm. the port work is 7cm on the exhaust housing

If your turbine housing is ported to a 7cm then that is the gasket you are going to get. How is your O2 housing ported?

its not ported but upgraded to a 2g o2 housing

If I were you, I would port out the wastegate passage on the turbine housing to match the 2g O2 housing. You want to do the bell shaped port. For the other gaskets, I would use the 2g turbo to O2 housing gasket and either 1g or 2g O2 housing to downpipe gasket.
