May 16, 2010 - Time for the headers!
I've built a couple of headers before - most memorably, the one for the Targa Miata - so I have a fairly good idea what I'm doing. In this case, packaging is my biggest problem. I'd love to do a nice equal length, long-tube header for maximum power but I simply don't have the room for it. So I'm going to settle for simply fitting everything in place. I figure it'll be lower restriction than the stock stuff (hopefully) and it's certainly not tuned length.
The key to making this relatively easy is the Ice Engine Works "header lego". It's a box full of little blocks that snap together. They come in straight and in 2", 3" and 4" radius bends. Each block is 1" of tube, which really helps when it comes time to make primaries of a particular length. In this case, I'm just trying to get things to fit. There's a fairly massive length difference between the front and the back cylinders.
The initial mock-up was done on the car and transferred to the work bench.
