I've been working on upgrading the components of my custom fuel injection setup. One of the upgrades I've had in the works for awhile was adapting the newest Bosch injectors. These have an improved spray pattern, are high-impedance, and are available in a variety of spray volumes. And they're TINY!

But like any of this stuff, you can't just bolt them on. I decided to make some fancy adapters that would look mostly original. This was one of my first projects to help teach myself Fusion360 CAD modeling.

Got a couple 3D prints from some of our members, which illustrated a few issues with my design. A few changes were made and I pulled the trigger on an initial run of 20 pieces (5 engines).

Just received these parts back from anodizing and did a final test fit. Everything looks perfect. So it's time to install this and my upgraded AAR on my 1.7 Turbo and see how these new additions help things.
