So...I decided that I would post a few of the as build pictures of the intake manifold. It all started as a discussion of who of the 5 Urq's in Las Vegas was going to make it up to Colorado in August for the URQ25 event. I'm not sure about the other 2 in town, but between Sean's, Hank's, or mine Sean's in the best example and one that really should be there. It really is a well put together car, so the Las Vegas Urq geeks decided to pull resources and do a one off mani. Sean did the wrenching, Hank the welding, and with the input of all three I designed, cut, machined and in general tediously hand massaged this one off.
We talked about a straight up MC mani, but didn't want to fight the injectors and wanted as much I/C room as possible up front. We had a 4kq mani that feeds from the rear, but really wanted something different so we began with an MC manifold figuring we would feed it from the rear the way the runners are angled.

I cut the top above and then below the idle valve passage.


milled the top for flatness and square.


Cut a 1/4" plate to extend surface area and make sure the runners underneath were sealed.


After welding the welds were milled flat again.

11/4" holes were drilled into 1/4" plate and 11/2" holes into the bottom of the D shaped extruded channel we used for the top. The bottom of the channel had been cut off to take a wedge out and make the channel taper.


They were then stacked on the runners, welded and hand ported.





A 3" aluminum 1/2 sphere was cut to fit the end and the top was fit and welded.

Once the top was welded we test fit it only to find out the tube header hit. :frustrated: After looking at it for a few days we cut the top off again, made the correction and rewelded. It should flow better than stock and looks hot!
