Now that we've got a decent welding rig at work, I've been thinking for the next go-round I might try making one that looks like a BMW intake. :) I've been grabbing parts everywhere - there's some GM parts in the ignition, the fuel filter is meant for gas pump applications, and I also used to have a few Mitsubishi parts in there.
Good stuff, BTW what does a setup like that trap in the 1/4?
