what size gaskets do i need for porting?

[greathuskie]

i know i need the ford cat gasket for the o2 housing, but what about the exhaust manifold?

I would order the 02 to downpipe gasket from RRE. Much thicker. The ford catcon gasket blew out in 3 months of use for me.

RRE also has a very nice 7cm exhaust manifold to turbine housing gasket. I would suggest this as well.

Depends on which exhaust manifold you have. You can use the stock gasket if you aren't doing any major porting. Your profile doesn't say much which makes it kind of hard to help. Does anyone know where you can get a 6cm exhaust manifold-to-turbine housing gasket? Also, what gasket do people use to go from the turbine housing on a 14b to a ported 2g O2 housing?

my car is basically stock right now (intake and MBC) so im just looking for something that will be good to do while the o2 housing and the exhaust mani are off the car

which gaskets will i need from RRE? and can someone tell me exactly what a flange is?

You could order the evo gaskets from conicelli and then port everything out to that size.
