Question for the custom manifold builders!
Im seriously considering building my own turbo manifold since it'd cost only around $80. I have a TIG, a MIG, and an arc welder, and air grinders/cutters so cutting and welding it together wouldnt be a problem.
First, i was wondering if where the tubes meet internally, are you supposed to weld those areas? or just grind them down so there's no rough edges?
Second, I was wondering where I could purchase the pipe, particulatly the T-mandrel bends?
And finally, third, are most manifolds constructed with 1.5" piping? I think I remember reading this before, but have never measure a manifold.
Thanks guys

Re:Question for the custom manifold builders!
the pipes/bends for the manifolds i've made (D series honda manifolds) have been Schedule 40 1.5" long radius 90 degree bends, and Schedule 40 1.5" T's
i beveled my edges and left just enough land to allow full penetration without a restrictive lump on my root pass.
(mig welded)
if i were you, i'd tig mine. if i had a decent tig setup i would have tig welded mine, it's so much cleaner.
as a matter of personal opinion i don't really think anyone needs schedule 40, it's really thick, you could get away with a much thinner wall thickness.

Re:Question for the custom manifold builders!
Hey thanks for the awesome reply
One more question though, I found where to get the regular 1.5" 90's (jcwhitney) but I cant for the life of me find the T's. I saw them on some site about 2 months ago, but have no reccolection on where to get them. HomeDepot or a store like that doesnt sell them, do they?
Thanks man !

www.mcmaster.com go to pipes and fittings or whatever it is on the home page and go from there. or go to the searh engine in the website and search "butt weld fittings"

Thanks guys
I found what I need with the sites listed and I'll check around locally on Thursday and see how it goes. That'd kick *** if i could find someplace where I wouldnt need to pay shipping to send mandrel bends all around the country
