Title: tube header

basically any older 8v vw exhaust manifold fits, not just specific 1.6td parts. so if you can find yourself a turbo header off of a older GTI or ABA engine, it will bolt right up.

here is one I have been home building.....I am running mine with a 40mm External gate...But I wanted mine to point up for easy turbo access

I still gotta make two more notches for the two center runners..but it's getting close..(moving to a new house really slows progress ;))

what steel did you use for the exhaust flange looks to be at least 1/4 inch lol, yeah that looks awesome, gonna flow a helluva lot better than stock :)

now if i was going to fab up my own header, should i use the 1/2 steel plate for the flange or 1/4 inch plate??? I know the 1/2" will definantly hold up to alot of abuse, but 1/4" is fairly beefy as well.

for a turbo manifold I would go 1/2" myself...if your gonna build it you might as well build it right.

I don't think 1/4" is thick enough for exhaust flanges near the head/turbo.  I'd go with at least 3/8".

Andrew

yeah for something that will heat cycle over and over at high temps I would want something thick!

1/2" or 5/8" for the flange, port match for size to the turbo, then open up the exhaust to at least 2.75".

Are you TIGging that or going with a MIG or ARC?
