So i recently ordered a GTX3071R Turbo kit from Mambatek on eBay Price: $1200 The kit came with: Mambatek GTX3071R (dual ball bearing, water and oil cooled) Braided line kit (Oil in, Oil Out, Both water lines) Braided line banjo fittings and nipples Metal Exhaust Mani Gasket Vband clamp and flanges The quality was mint when i pulled it out of the box. Spun perfectly, no shaft play what so ever. Came with a balance sheet from "Schnek" (have to check spelling on that one). Mocked it up today on my D1 Stable Steam Pipe High Mount Manifold. It sat great. looks great. excited to see what numbers it pulls from the tune. I've been talking to the owner of mambatek on facebook, and will be putting up a dyno run later.
tbh, build quality seems even better than the kinugawas. will keep you all posted with dyno results.
