Mocked up the hydroboost today.

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.

 

Had some fun with my origami oil pan tonight. got most of it welded up before i ran out of argon.

 

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.

 

I had planned on waiting till i get the old pan off before attaching the pan to make sure i get the sump in the rear.

Okay, that is good. Sorry for the inconvience. How did it all bend and fit?

 

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.

Yea I generally bend over the edge of my work bench and then lightly persuade with a mallet

 

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.
