Turbo that will support 350+ hp for my b18
 

Just what the title says. Im looking for a turbo that is in good condition that will support 350+ hp. I have a T04 40 trim that will get me close but I cant find anybody that will rebuild it for a good price. Im looking for a holset, a gm 1-8 turbo, a ching chong 57 trim would even work. I just dont want to spend $200+ have my turbo rebuilt and not be able to break the 325 hp mark, when I can spend around $100 for a used holset or something that will take me well beyond my hp goals.
