I am selling it because it has too much hand-finessing to be copied, and I need to start making my products fit with things people will actually have, like ported stockers.
the development history of this was documented here:
http://www.turbododge.com/forums/f4/...-progress.html
Design:
-custom collector, 4 to 1
-primary lengths of 15" for #1, #3, and #4, with #2 about 19". +/- 1" for all.
-primary are 1.5" OD, 16 gauge, 1.375" ID
-entire construction is mild steel, TIG welded
-Primaries were crushed to size and then inserted into head flange all the way up to the head surface, and then TIG welded INSIDE the flange. Same on collector pipe to turbo flange. I believe this greatly improves structural rigidity and improves durability.
-Turbo flange is braced directly to head flange with TWO 1/2" dia. steel bars.
Condition:
Has been installed since around 6/12.
Has about 8600 miles on it.
I dont see any cracks. Its a bit rusty.
Fitment:
-locates turbo in stock location
-fits with stock 1 piece. I would assume 2 piece. And also BMF.
-requires the smaller starter (I can identify precisely which one.)
-requires a special starter heat shield (included)
-hugs the 2.75" swingvalve very close. Its possible a custom 3" swingvalve could be made to fit though, I think. I held up a 3" 4.5" pipe to it and it looks like it might clear.
-needs the Saginaw power steering pump bracket modified to fit (simple. I can provide instructions. )
-not sure if it will fit with the ZF pump. I can test that though if desired.
I will provide technical support for fitment!
