I was gonna save this progress for my video, but that is just too much of a pain in the ass. The intake is coming along, I got the throats to all of the ports radiused in, and built the remainder of the transitions to get the air from the throttle body going the way it's supposed to go. To recap, the intake runners are built from 16ga. 1.750" exhaust tubing. The finished inside diameter of that tube ends up being 1.625" Considering that the stock port in this weenie head is 1.400, that leaves about 1/16" all around that I'll have to blend. The rest of the thing is built from 2.50"16ga. exhaust tubing. I split a 2' piece that acts as the front of the manifold at the runner entrance, and split a 2.50"J bend to make the back turns. Finally, I'll plate the thing w/ 16 ga sheet metal. The intake flange plates, and the TB flange plate is made out of 3/8" plate. Now I don't know if the stupid thing will work or not, what I know about intake manifold design could fit on the head of a pin. All I know is that the turbo intakes I've seen on BMW's, and certain Jap cars kinda look like this, so hopefully, I'll be OK. Tommorrow, I'll fit the injector bungs, and the TB flange plate, then weld that sucker up.
