Ebay twin turbo setup Checklist...Turbo a SBM for under $1000? :)

I have been looking into them for my truck lol I want to build a gas ram 1500 that will run with these stupid diesels. There is a guy on YouTube that actually has good things to say about the Ebay turbos he does say stay away from the cheap waste gates and spend the money and get a good one! But the smaller t3/t4 turbos will make a good serviceable turbo. I will see if I can find a link to his video
