The fancy(?) airbox I built works well now, but is a tiny bit big- it sometimes touches the wiring loom, and you can hear it vibrating through the firewall. It’s almost like I built it to suit a car without an inch of Dynamat on the firewall. Weird.
It’s also a bit rectangular. I’m sure I can make something better. But first we design it with CAD:
I have discovered the joy of using a former. Spending half hour making something you were only going to throw away seems like a waste of time, but it makes shaping the sheet metal amazingly easy, and very accurate.
No, I’m not showing what the welds looked like before linishing them back. Pulse welding might keep the sheet metal from warping, but it’s not pretty.
Test fit box, add an air inlet, and then paint:
So pretty. I even treated it to a new air hose, since the old one was a bit crap. Rubber end seals made out of a bit of old gumboot for Kiwi authenticity.
The new air filter is from a Nissan Tiida or Cube, a 1.6litre engine that makes 112hp, so it should flow enough air.
