Tubular Header Fabrication Attempt
Key notes :
1) Stainless flanges
2) 1.5" Tubing
3)Runner length 28 inch
4) Stock dsm turbo locations
5) Head flange to radiator 9 inches
6) flange to timing belt 3 inches
7) height limit 6 inches from top of flange
8- No provision for dipstick ( will be removed)
One of the challenging things for me in regards to this manifold, is the proximity of the turbine inlet to exhaust port of runner number 3. With that being said , I had to get creative with the location of collector in regards to that specific runner. Inorder to try and accomplish this, I had to pie cut the entry to the turbine housing, as the picture below illustrates. Keep in mind that I was also trying to ensure that I can get to the bolts and nuts to attach the manifold to the turbo , as well as the cylinder head.
Once I had this portion oriented how I wanted, I began to construct Runner #4 as it would be the longest one in the manifold, and where I need to get a given length. A shot showing the collector , runner number 4 complete, and the start of runner number 3
here is front shot, showing how far down runner 4 goes down, also I hope I have enough clearance for the wastegate that is off the turbine housing.

Runner 1 and 2 are going to "side wind " past the timing belt area inorder to attain that 28 inch runner length
More to come as I move along...
