for you turbo experts, im considering cutting 1 tube off of a truck manifold and using a few sch. 80 weld sockets to make an extra bend in the manifold before it meets up with the rest of the cylinders. I wont be doing the welding, there is a cast iron guy by me who does amazing work. My concern is, will the weld sockets I add in be more likely to crack because of the 2 different metals expanding differently? I figure it wouldnt be a problem N/A but im worried about the extra heat. I would really like to use the truck manifolds for the sake of keeping it simple rather than building something custom for one side of the motor. Thoughts?

Keep it simple, stupid. search around as there are a few guys running similar stuff but im sorry i wouldnt trust it.

so something like a log manifold might hold up better even with all the extra welded spots? I figured the more welds the worse it would get, and actually though the modified manifold was simple. Stupid

i have seen some guys cut the pipe side off stock manifolds, weld extensions or diff ends on, for turbos, seem to hold up, with the proper filler rod/metal

ok, thats what I was wondering. It wont be supporting any weight other than its own, so there wont be much strain on it.

I did this with truck manifolds and schedule 40 pipe fittings. I beveled the manifolds and pipe fittings, pre and post heated with an acetylene torch and just mig welded them to the manifolds. It welded clean and I haven't had any problems with them so far. No turbo supports, going on 2yrs and 7000 miles.

Now, if you are going to just modify one runner on a truck manifold I'm not sure how well that would hold up. May end up cracking due to dissimilar expansion rates.

Snyper did it too, in his 350Z with a LS2 and a PT88, search his name and look for the build thread.

EDIT: stupid LOL

So did RICE ETR on his latest modification, as well as tirefryin_s10

We have done it a few times with great success.

INTMD8- what filler metal did you use?

hellbents10-did you use a similar pre and post weld heat? what filler?

on one runner or just adding a different collector? Ive seen that plenty but I havent seen much of just changing one runner

theres mine. Welded inside and out to mild steel.

I think im just going to give it a shot on cutting that first tube off and moving it and hope for the best. Might even throw some v-bands on the collectors while im at it. Thanks for the pics as well guys.
