Hey guys new here...

I have searched and searched and can't figure done stuff out, figured I'd ask the experts lol. I have a 2007 mazdaspeed 6, which currently has the stock k04 turbo on it. Just before clicking "buy it now" on the Godspeed gt2871r I was going to purchase to upgrade, I noticed that my k04, and turbo manifold have a vehicle specific flange. It looks similar to a t25 flange but is wider on one side. So here's my issue. I can't find an exhaust housing for a gt2871r for my car. And I don't know enough about turbos to know what hybrid ---- works. If I buy a gsp gt2871r can the stock k04 exhaust housing be used? Will it fit the turbine? If not, anyone know where I can find a exhaust housing without buying the crazy dxoensive ATP Garrett gt2871r? Or another way this could work?

Thanks!

And before someone says it... I know I could buy an aftermarket manifold, but I already have a 3" downpipe and would like to keep the setup as cheap, simple, and stockish as possible.

I have seen bolt on GT3076's for sale. Not to sure of the quality of the Godspeed GT2871, but the BNR stage 3 oem upgrade is good for moderate power. It uses a GT28 center section & compressor wheel with a larger housing & the factory exhaust housing.

BTW I'm assuming you have some sort of fuel control Cobb or CP-e & the fuel pump needs to be modded.
