What's the best turbo for a 6.0
 

I have a 06 f350. I have a aftermarket oil cooler, deleted egr and cooler, heads have been studded and replaced, sct x4 programmer, and a mbrp 4" in turbo back exhaust. I've been looking at getting a Garett powermax turbo with a whicked wheel and was just curious at how hard the installation would be and what else I would need to install it i.e. Gaskets and such, and if also it would be worth the time and money to do it. This will be the first turbo I have installed by myself and I'm by no means a seasoned diesel mechanic. From you tube videos it doesn't look as difficult as I'm sure it is.
