I have used a .60/.36 T3 Garrett. Loved it until the seals went out and leaks oil badly. Now I am back to stock with a way badass intercooler setup. Totally loving that, however, I still don't like how tiny the turbo is. And I am going to have the opportunity to get a new turbo thanks to my tax return.
I am thinking something like this.

I am thinking this because its cheap for being new, and Its huge so It will flow tons of air. Also the ease of installation. I will be changing the turbine housing to the stock .36 A/R wastegated housing. Just to keep it simple.
