I was really impressed with my Silver 62 from II. Ran well with stock injectors, and was still doing well with my small nozzles. Put me over 600 hp just fine. After my II, I purchased my newest turbo from Engineered Diesel, and I can't say enough good things about this company/their product. You could give Engineered a call, they can build something specifically for your application with room to grow or whatever your current goals are. :thumbsup:
