I tried searching, but only seemed to find SR/Z32 mafs stuff. I'm making an intake to move to the passenger side on my S13... I need to know what size piping to bend up, coupler sizes, and where to buy vacuum fittings? I started a project, and didn't think it through. I cut my old intake, and to make it fit I had to cut pretty much on the 90 degree corner, and right at the vacuum fittings... so I cant use a coupler. This weekend I'm just gonna weld up something to work temporarily until I can get a nice aluminum one made up.

From what i recall the piping I did have was 2.75", but can't remember for sure.
