I also started on the turbo adapter and ran into a slight problem. the uppipe flange studs are tight against the uppipe leaving no room to turn a nut. What have others done for the ko3? I could notch the uppipe for clearance but this will disrupt the flow going into the turbo. Never mind the adapter being a little bit of off kilter, its just tacked and ill true up the uppipe on the mill before final welding.
And boy, it doesn't take long to turn a little one car garage into a mess.
I've always used a pipe that has the same ID as the manifold and that leaves plenty of room for the nut. Too large ID pipe could reduce velocity to the turbo.
The pipe I used was the same ID as the largest portion of the exhaust manifold. This made the ID of the pipe bigger than the ID of the turbo. That and I was trying to use the heaviest walled pipe I could. So this evening I made 6 little pie cuts and gradually reduced the inner diameter of the pipe to match the turbo. it looks like nuts will clear but i currently do not have any to try.
Thank you for the pictures it reminded me. Over the thanksgiving holiday I welded up a pan and the guys in my shop didn't mark the front of the pan flange. Please double check the flange as it is not symetric. Very sorry for this confusion.
The bend fit was great, easy to bend, and a couple needed a little persuasion with a hammer but not a whole lot. The front lip that gets welded to the flange will have to be trimmed just a little bit but I think that is due to me putting to much radius in the bends. I bent them by hand and unsupported, if I would have put it in the brake or clamped a piece of metal at the bend i could have reduced the radius.
Been out of town for a week, so didn't get much done. Extended the oil sump today. Its ugly but holds a vacuum. Started on the turbo drain in the pan but couldn't get it seal, couldn't weld the top withe the flange already welded on. I cut it off and will weld a new one on but at 90 degrees instead of 45 so I an get the tig torch in there.
