I have a 8 -10 foot peice of 1 1/2" id stainless pipe in the garage. can it be used for anything, oh, and the sidewalls are THICK like, 1/4". Can I use this to build a manifold? if not, what could I use? is the prebent stuff in the autoparts stores worth anything?



I also have a big peice of 2 1/2" id stainless, that is polished https://www.nopistons.com/forums/pub...#>/biggrin.png Thats gonna be intercooler piping.

1/4" thick wall steel tubing, hrm, sounds like a ballast weight er i mean font bumper support from a old porsche.

yea, its heavy. lol, but the stock one is no light weight!!



but, will it work?

sure if you can weld it.

why wouldnt it?



good luck bending it, you will need a decent welder to get penetration on 1/4" steel too. I don't recommend using it for this purpose personally, get something thinner, easier to work with, and lighter.

thats kinda what I figured, what can I use that would work better? and how thick do my plates need to be where it bolts to the engine or turbo?

If you can, Inconel or 304 S.S. ? (i think that's the good stuff)

haha, good luck welding that ****.

1.25" is too small ID main runners. 1/4" wall is over kill also. I made mine out of 304" sch 10 pipe. It has a wall thickness of 1/8 and is cheep. I got the weld els from mcmaster.com for 4-5 bucks a piece and went to the local steel yard and picked up the pipe for cheep also. I made my flanges from 1/2" 304. I'd stick to 1/2 so it won't warp as easy when you weld it.

Thanks!! is there somewhere I can get prebent? I don't have access to a bender https://www.nopistons.com/forums/pub..._DIR#>/sad.png

just buy mandrel bent elbows, cut & weld. https://www.nopistons.com/forums/pub...DIR#>/wink.png

The weld els I was talking about are cast "mandrel" bent pieces, cheep and as durable as you can get.

I guess its time for a trip to the industrial supply store, what grade of steel or stainless is best without costing an arm and a leg?

I like 304L schedule 10 pipe because it's cheep and easy to weld

cool beans, so it tig welding better on a manifold?

Yup, TIG worked awsome. Most of my manifold I just fusion welded, only used a little filler rod here and there..

cool beans, I'll post pics when it starts coming together
