I've been working on putting a 6.5TD in an older truck and am having a little clearance problem. With the way my firewall and frame are, I can't fit the turbo downpipe past the manifold on the passenger side. If I could shorten the manifold, I think I can make everything fit. Heres where I'm thinking of cutting it.
I can't really find much on welding manifolds. I have a tig welder, just not sure of the process. Any help would be appreciated.
I had a similar problem when I put the LQ4 into my '72 blazer. I cut the stock 3 bolt flanges off the manifolds and welded some mandrel bent exhaust tube with a v-band clamp onto it. I just used my MIG and have had zero issues so far, but since yours is feeding a turbo you will have higher temp/pressure and you may want to use a high nickle rod and TIG it. Here's a couple pictures of what I did.
