ok on my last build i used steel all the way from the turbo to the engine. i used it becuase it was cheap and i could weld it with my welder myself. now on my new kit i'm at a cross road right now. i havnt ordered the pipes for the charge pipes yet and was wondering this, should i use stainless steel or go alum this time. i want to go alum for the fact it's super light weight, but my problem is i cant weld it as i dont have a tig welder for that, i dont weld enough to make it worth buying a tig welder for this one job. then you have the stainless, i can weld that but was wondering how much heavier it is compaired to the alum. i know it wont be as heavy as my steel version but i want to be able to save some weight if i can.

what are yall doing?

you could always get a spool gun to weld alum with your MIG.... much cheaper than buying a TIG setup.

??
have more info on that?

or do the common sense thing, and just use stainless.

Taking a good dump would save as much weight unless your pipes re huge.

or use tape to hold the aluminum and mark it for alignment and take it to get welded

i was thinking that but i would probably screw up by a **** hair and have to redo everything

it depends on what you have for a welder but for example i have a Miller 180, so i go on the site and look up accesories and search for a spool gun that works with my welder.
for my 180 a spool gun setup is like $200 or so, totally worth it compared to getting a new TIG machine just to do alittle bit of AL. now i plan on getting a diversion 165 for my home shop so i cant say how well the spool gun setup works but i know a few pro's that have told me its worth the cash when you just have a little bit to do like you would.
if it was me, id probably just do it in SS since i have all the stuff to do it but for some every little ounce makes a difference so i can see why you would want to do AL. not a bad thing to be able to know how to weld AL, it comes in handy quite a bit

i like to learn a new skill or something everytime i have a chance. like you said, everylittle bit helps. im going to have to see how much it would cost me for my lincoln

i couldnt agree more brother. im living proof of what a guy can do with a little bit of knowledge (usually a scary thing in my case ) and a decent tool / equipment selection.
if the spool gun setup is no existant or super expensive, id take a look at some of the newer hobbyist TIG setups that have come out. the used stuff is alot more affordable than one might think.
