Should I Purchase Buschur Ported Exhaust Manifold?
So I am ending up Switching to E85, I have a Tomei arms m7960 turbo, cams, cam gears, intake, full exhaust and a tune. About 340WHP. Should I purchase the Buschur Ported exhaust manifold and install it so that way they can just retune everything? How much WHP should that Manifold net me?

Since they aren't too expensive, I would say to get it. It's a good bang for the buck. It'll certainly flow better than stock. Really nothing to lose.

I, too, prefer Curt Brown's port work. Great price advantage on most things, and has all been proven performance-wise.

I bought my car with the stock exhaust manifold ported by Buschur on it and when I took it apart and cleaned out all the carbo I was disappointed in the porting work done to it....I would go with one of the above mentioned

Someone should do some un biased testing. I have a stock non ported manifold and a buschur ported manifold brand new. I might be able to do some back to back testing on a mildly modded evo on a stock turbo. Id love to be able to get my hands on a Curt brown ported unit and a MAP ported and see once and for all whats what, but I would only be able to test the ones I have at this point.
