N54 exhaust flange CAD/CAM drawing?

[NJrep335i]

I know it's like a 5 years old thread, but Roys old link for CAD drawing doesn't work anymore. Any chance someone of you have the cad files and could upload them?

As requested.

I had a set laser cut sometime ago and they were decent. If I recall, the company had some difficulties because of the line smoothing. Personally, I would get a set from RB which I eventually did anyway. Good luck with your build.

My dilemma is V band vs twin scroll manifold build

I am a alloy tig welder, I do back purged SS and Chrome tig welding at my job.
a buddy of mine, also n54 335 owner are planning a single turbo build. I plan to use a 5862 or 6062 ball bearing.

From a fabrication point of view the JP works bottom mount V band turbo manifold is by far the most builder friendly.
The part count is the lowest, and the fitting difficulty is the lowest. After sourcing the manifold flange all you need is (4) 90 degree elbows the tube and V bands and oxygen sensors.

building A True twin scroll manifolds is 5 times the work of a Log style v band. It is do-able but does any one know if its worth the work?


I have been reading alot about twin scroll. and since i have an AT i dont want to peak past 550 AWHP anyway.
sooo if twin scroll is better for spool and suited for lower numbers , like those automatics can handle
(example of this being that motiv has a beautiful CNC machined Log style manifold and holds what i know to be the record hp n54 )

SO Is any one un happy with theyre log style, sub 600 whp single set up?

im not doing port injection or Ethanol ( there is none in edmonton)
Meth yes.
