I want a cummins 6bt in my truck too, learned a lot reading this thread.
Where can I find this emblem?
He made them up for me. The 'Special' isn't embossed like the originals but has the correct 'look'.
Been using the truck a good bit but haven't been real happy with the turbo. When I installed the 16 cm3 turbine housing I ported the divider ring and it wasn't happy, would huff around 20 psi of boost and not perform. Yesterday I preheated it and welded the divider ring back up where the gass's impinge on the turbine wheel. I made several hot passes completely around it so hopefully the weld will stay in place. After cooling for a couple hours I mounted my cut off wheel grinder in the lathe and used that the turn the ID so the impeller fit is correct. I'm hoping it makes a difference without toasting the blades. A replacement housing was $180.
