I can get this turbo (some shaft play), oil feed line, oil return line fitting, dsm blue top injectors, down pipe, wg block of flange for my mani, and 1g dsm bov for $150. I only have three questions. How much does it cost to rebuild a turbo? Is this turbo good enough for 250whp on a stock b18b1? I do a lot of highway driving, does that make a difference?
