turbo question
 

hey guys, im changing my set up this year andwondering what yall think, if its to much or not. im gonna keep my 5x.014, sdx comp dvs, no plate rack plug and 4k gsk on the fuel side. but im bout to get a cam, and get a turbo on the air side.

i called forced inductions, and talked to them about a turbo, and they sugested a s472/83 in a T4 .90 housing. what do yall think about this turbo for an auto?

any one have any ideas on this turbo on my truck? would i need an external wastegate? or would i be fine?
