Stricnyne- You just don't wanna defy convention do you? If you sit down and pay attention, even YOU can build a manifold for yourself, and not pay through the nose.
Sxracerb25- I'll tell you though, in your busy life you definitely don't have the time sending a $1500 manifold back and fourth a few times to make it fit, that's for sure.
Kansei240sx- I think I understand what your saying...kinda...? (Not really)
Here's the "secret"
Step one:
Get a 6-cylinder collector from vibrant performance. $140.
Step two:
Depending on your runner length get enough stainless elbows and straight made from 304l 1.5" Sch 10.
Straight is $8/ft, elbows are $5 a piece.
Step Three:
Get a head flange from
http://www.bmcrace.comStainless headflanges are available, to make the whole mani SS.
Around $80 for Mild, and $160 for 304l SS
Step Four:
Get a turbine inlet flange. This one is $20 and SS.
Now that you have your materials you need some tools.
-110v MIG welder to tack everything together.-Chop saw, to make cuts. If your a baller, Metal Bandsaw.-Grinder, cut-off wheel
Now, you want between 12-16" of runner length from the head flange, to the turbine inlet.
Cut all your pieces so they fit FLUSH. Tack them together with the MIG. They must stay flush for the TIG to work. This will take the most time.
Since your collector is already built, and the Exhaust flange is CNC'ed to 1.5" on every hole, piecing your manifold together w/o welding should be easy but take your time.
As I said before there must be NO gaps. If there are any gaps the TIG will not be able to weld.
Now before welding your manifold should look *something like this tacked up:
Now the rest is up to you. You can:
1.Finish it yourself. (You have a TIG, can borrow one, or if you have access any other way)
2.Pay a shop to TIG for you. Either way its much less expensive then paying retail.
Backpurging: To cover the inside of a piece to be welded with Argon 100%, then finish welding.
TIG welding is so easy its ridiculous. The fine Arc control makes precision welding easy and comfortable. There is no spatter or arcing with TIG. You could technically TIG weld with your Sunday clothes on.
When your pipe fits with no gaps, and you are backpurging, and can run a decent TIG bead with or w/o filler that's all you need to make your own manifold.
It takes the same amount of skill to TIG weld a simple bracket, as it does to weld a schedule 10 piece of pipe.
And it saves your precious time from chasing down some guy for $1500...
