so your telling me that i don't need to buy another cast manifold if i simply get the factory one ceramic coated? i love the coating job, but i'd prefer something that is proven to add more hp... ya feel me?

You did a great job on everything! I have a quick question on the O2 housing you ported. I have been thinking for some time about removing my O2 housing and cleaning it up for better flow. Did you find that it was in bad shape from the factory? Yours turned out great. Keep us posted on your driving impressions.

Yes, the O2 housing had a lot of casting "slag" on the inside. The inside surface was very rough. It was fairly easy to port/polish, much easier than the manifold was!

Very nice job.
I ran this by an automotive engineer friend and he suggested the porting/polishing would do more good than the ceramic coating. He also expressed concern in bearing/oil life in the turbo at the elevated temps. His final thought was "stainless is better, but more $"

I am hoping that the added heat is not going to harm the center section bearing. I do let the car run for about a minute before I shut it off. time will tell. It has been only about a month since I installed it. It most definately increased the throttle response a good amount. The ceramic is holding up very well so far too...

The only problem I have with coating the intake manifold is that I would have to find a used one to purchase from someone. I can't take the one off of my car because I have to drive it everyday. Several people have purchased aftermarket intake manifolds lately so maybe I will be able to find one for sale for a resonable price. I will definately post that when I am able to do it...

I am unsure how well high-temp paint would hold up on the exhaust manifold. Maybe you could just paint the upper heat shield (easy to remove) and see how long it lasts. It does not get as hot as the exhaust manifold but might still be a good indication of whether it would last. I would recommend the Thermo-Tec 2000 degree paint. It says right on the can that you can paint headers, manifolds, etc...

Sorry EVOeight i forgot to ask in my last post. have you coated the out side out the housing yet? your turbo does look a little out of place in the pics against all that mat gray coating. people will start to think you've had a turbo fitted. LOL.
thanks Chris.
