I just bought s 50-trim Turbonetics BB Turbo, to replace my "china-made" 50-trim turbo that had a seal go out. Anyway, the 5-bolt flange is the same, but it seems like the flange on the downpipe is about less than a 1/4-inch off from fitting on the exhaust housing. I installed the turbo on manifold, clocked it, then installed it in the car & it seems as if its in the right spot as the old turbo.

Got any suggestions i should try?
