Turbo/Exhaust Manifold Setup

This was fairly easy and took about an hour. After receiving the wrong 4BT center outlet manifold, I chose to make my own.  What I needed was a 4BT center outlet exhaust manifold.I did this to have more room for my turbo outlet/exhaust pipe against the firewall. The rear outlet manifold would not fit without major work to the firewall and inside the cab. Moving the turbo is the easiest and best option.First, I cut off the #1 and #6 manifold flanges. Next I cut out two pieces from those manifold flanges to serve as plugs. Then I welded the two pieces in place and I was done.Welding this up was little nerve racking at first, considering the manifold is cast steel. It's actually a very nice cast steel with a low carbon concentration. This high quality cast metal was a breeze to weld on (I used a MIG). Just clean up your metal and do a test run on some of the scrap manifold pieces. I pre-heated the areas I was going to weld on with a propane torch for about 15-20 secs before welding. I also switched from end to end, between every weld, to prevent any one side of the manifold from getting too hot and cracking. Make sure you blow out the manifold when you’re done. You don’t want any stray bits of metal in your exhaust system before the turbo.
