An End-of-build Retrospective on my Rx7 Evo GT by gmonsen

The pictures below show the rather painful process of making the runners. I didn't realize how many curves there were involved. Again, its the combination of the taper with the 120 degree curve that makes it tough. Here are the last 3 runners before being welded to the plenum.

I'm getting excited. The runners are done. They now need to be ground and welded to the plenum. I should have the finished piece shortly.

Ok... How many pictures of a manifold can somebody post? Well, its basically done. A bit more welding it to the LIM-flange and some grinding and its on its way to KDR tomorrow. Next pictures will be on the car!

To get an idea of how much bigger and how much more air this thing can flow over the stock 20b UIM, here's a photo of the new plenum with the stock 20b manifold behind (inside of) it.

Victor can't take still photos very well...

This shows one of the runners having had the welds ground off, but not polished...

So, here are a few more pictures from this morning. The runners have the welds ground down and he is now welding the runners to the plenum and LIM-flange. You can see the differences -- and similarities -- here between the original stock intake and the new one.
