My stock turbo finally took a crap on me, I recently purchased the gt28rs Garrett turbo was wondering what all I need to do and what all I need to install this turbo?

You'll need to clock it, modify the WGA bracket and get a reducer for your intake. Other than that, it's pretty much a drop in replacement for the stock one.

What do you mean by clock it? And what kind of modifying will I need to do to the bracket?

Also the gasket that goes between the exhaust manifold and turbo has been discontinued by Mazda, anyone know where I can get one? Im gonna check and see if Garrett makes one

atpturbo has most of the parts for any turbo install. you need a t25 manifold gasket, and likely a t25 5 bolt exhaust downpipe gasket. most of the oil and coolant lines should work without modification.
i personally dont know what mods will need to be done to the bracket, probably shimming of some sort but this is a good opportunity to replace the waste gate actuator as well with the atp one.
clocking the turbo just means taking off the compressor housing and pointing it a different way.. many people point it down and route their fmic to suit.

Did you get a specific bracket for the GT28?

If you are still using the actuator that came with the gt28 you can clock it more and just make a small plate to offset the actuator rod.

like so
