S91 Build FeedBack. Is this Reality?

S91 Build FeedBack. Is this Reality? Ok I need to check my options to keep me sane on this build.
I can hit this thing 3 different ways.
1) Full custom headers. I would have to scrap all material I currently have. Headers alone are $2700.00 completed. Then the cost of cold and downpipe added in.
2) Do a custom log setup which I have all of the materials for currently. Use the stock drivers side manifold on one side and log on other.
3) Use the C6 manifold on the passenger side with a up pipe to the turbo. Make a cross over pipe and down pipe. Again I have all material on hand.
I know option 3 would be the cheapest and fastest way of getting everything completed but what are your views.

If you can plumb it I see no need for running custom headers beside for looks. I run truck manifolds with my s91 and don't feel I would pick up anything or we would build tubular headers.

I think I am going to go with the C6 manifold setup. My builder was worried about the support of the turbo and the stress. However we can make a support right off the frame rail to solve this issue so thats where we are leaning. I am also running solid motor mounts so I dont think there will be any issues.

Since when do you need a $800 collector to make power with a turbo? I was told by some of the best turbo tuners in the biz,you will see 0 gain with a high dollar merge collector.
BTW:They do look pimp though...haha

Yes weld el's from mcmaster are cheap....and way better than using tube elbows. I see head flanges all over ebay for $50-60. But I laser my own. Same with the T4 flanges.
Why you need a fancy expensive merge collector is beyond me. Just cut the pipes at an angle and weld them together.
As a former pipe fitter/welder of 9 years in the high pressure natural gas feild I know for a fact thet the weld el's will hold up to heat cycles and vibrations well beyond any thin wall tubing most headers are made of. Weld el - about $8 a peice. straight pipe - abour $60 for 6 feet. Way more than you'd need.
You want an easy collector, use some flat sheet metal. I forget what gauge I used 12 maybe? But instead of forming the radiuses like I did, theres no reason you cant have a seam there welded. All a collector is, is 4 triangles welded together. Wont look as pretty but cheap.
Material into these BMW headers aprox $250. Time - not nearly as long as one would think. Its cut and fit...pretty simple, This passenger side header, simple I could make in an hour or two.
So yea.....$2500. is a lot. Even if I charged $100. an hour
pic of formed sheetmetal collectors. All i did was measure the 2 ends to join and formed them useing a large radius die on a press brake. 2 peices of scrap metal and about 10 min.
Pic of collectors just made by angling the pipes. CHEAP AND EFFECTIVE. And if you think it looks like **** because I didnt spend $200. on them I dont care.
The reason the headers cost 2500. is because they monopolize the market and have you convinced that no one else makes them, they are that much better, and welding up a set of headers for a turbo is rocket science.

I proved it along time ago.
You spout off the same $250 turbo header crap in every thread that brings it up. Do everyone a favor. Build your $250 turbo headers. Sell them for $500. Double your money, be everyones hero, make more $$$$$ than you can spend.
We will all sit back and see how long it lasts.

Some guys will never learn.....My next set of headers goes like this...
$175 flanges 304ss
$225 for 16 90 degree elbows 304ss
$175 for 304ss collectors(not junk)
$575 in parts alone
It probably takes me 8-10 hours to complete a set of headers mininum. Figuring $70 an hour thats another $700 + welding rod and consumables for a basic set of headers.
You get what you pay for, pay for junk you end up with junk.
