The basic parts(Weld Els and flanges) are show in the picture above. this is basically a hit or miss, guess and check type thing. first thing i did was cut the Tee's and lined them up on the flange. then i did the same for the elbows. I welded the tee's and elbows together first, then welded the whole piece to the header flange. below are a pic of the Weld els and header flange, along with the manifold when I finished. i sprayed it with Copper Spray-a-Gasket, and it produces the gun metal shown(you can see on the header flange that some of that copper hasnt burned off yet). After the main section is done, i threw the manifold onto the car, and lined up where i wanted the collector(which i got here
http://www.jgstools.com/turbo/index2.html which you can also get the other manifold supplies) to go. then i cut the hole out with a whizzer wheel, and welded the collector onto the manifold(had previously welded the collector and t3 flange together). All of this welding was done with a Mig welder(and they are some of the ugliest welds ever but they get the job done). you can also drill and tap the EGT probe in the #4 cylinder now if you have an EGT gauge.
