Here's an example of a typical design which fits the available space.
Flange:
I've seen some people on here go from CAD designs (for laser cutting) to chopping the flange off a header. Regarding the latter, I only have the stock cast iron manifold available. The former I know I won't be able to find the time to draft up. This guy on eBay is selling a couple of cut flanges: 1 (more expensive), 2 (less expensive)
Tubing:
I have a pipe bender and chop saw back in Louisiana, though am planning to purchase pre-shaped tubing pieces. The tools needed for grinding and cutting are here with me in Kansas.
Turbo mount:
TD05 16G flanges and gasket sets are easy enough to find through online retailers and eBay for under $20.
Extras:
- O2 sensor bung
