I had a 90 welded to my turbo as well. I didn't like the silicone coupling being that close to the manifold. Looking good so far. I know you're getting excited about driving it now. I took my pistons and rods to the shop this morning to have my block rebuilt with +.040 pistons. I'm about two or three weeks away from driving mine again, and I can't wait.
P.S................OUCH!!!!!!!!!!!
