o2 housing porting Q's

[mitsugsx95]

I am getting a stock 95 o2 housing for cheap and am going to port it during the winter season along with getting some other mods in place.
Any tips on how i should go about with the porting and i think you use a 7cm gasket for the out let to match it to the dp, right? Other tips on porting the inlet as well.

Oh yeah, what about porting the 95 exhaust manifold as well?

These topics are covered in detail on the VFAQ website. I was able to port both my o2 housing and exhaust manifold after reading the instructions there. Check those out and see if you have additional questions.

Yeah, ive seen that before and its a good guide, but do you need to get a new gasket for the tubine side of the O2 housing? Im new to porting things so i really dont have that much exp.

You will need a new manifold->turbo gasket because the turbine inlet on the turbo will be port matched to the exhaust manifold.

You will need a new o2 housing->downpipe gasket because the exit from the o2 housing will be larger. (If you have a stock exhaust, this causes a problem)

No, i have the n1 dp. I looked on the vfaq to see what size gasket to get, but it really didnt tell me which one, just said a ford 4,6,8, cyl. Does that mean you need it off of a ford exhaust part? Know what store to get it at?

Taking off the exhaust manifold and the o2 housing is a #@%#@%#@%#@%#@% trust me on that one. If you do get it done you will tell a difference. My car almost seemed somether and like it was spooling faster but smoother, of course i was still being layed back in the seat at 19 Psi on the T to small here. yeah i know if it goes i have an exuse for buying the Big T28 killer i want that much quicker. As of now the darn thing is holding 19 well. Depending on how good you can port stuff you could make a 10 hp gain in doing that turn into a 1 horsepower gain if you dont do it right like the vfaq says.
