so theres oil all over the bottom of my turbo and i look inside it intake side and the fins are beat up and the housing is beat up so im in the market for a new turbo and my question is which turbo should i get? im slowly building up and my max HP will probably be 500HP because its my street truck. im looking for a single turbo setup that will hopefully last that whole range of 250HP to 500HP. thx in advance. $$$ is probably gonna be to $800 budget and im not picky with new or used
