Like the title says, Just rebuilt an Evo 3 Big 16g turbo and bought a 2g manifold that had a flange on it for a 38mm Tial sport wastegate. So I put the turbo, manifold, wastegate on last night and the car is not creating an ounce of boost????? What the hell did I do wrong or what is causing this. I brake boosted the car didn't get any boost what so ever, ran a line from the j pipe nipple straight to the wastegate to run wastegate pressure, tried a manual boost controller in between the two and still no boost. I didn't mess with any of the intercooler lines while doing the install, and the turbo before this one boosted fine so I am totally stumped. i took apart the wastegate today and it seemed fine, the piston seemed to move ok and nothing major stuck out to me. Any help would be great thanks.
