rusted brake line/need to remove turbo/so UPGRADE TIME/Where to get upgrade

I am in the middle of a big repair due to a rusted brake line and a rusted fuel line. I need to fix the fuel line first but and waiting for parts. Then I need to have a mechanic fabricate and replace the brake lines.

Because of that he need to remove things in the rear of the engine, like turbos.
So I figured it would be the perfect time to do a turbo upgrade

The mechanic recommended 13G turbos but I can't find any at a reasonable price.

I am running stock boost and fuel configuration. In the warmer weather, and dry, this is my daily driver so I need to keep it road worthy. But a little extra horsepower is ok :cool3:

Anyone know a supplier?
