Sorry to have done some of it first
I have some intake parts you might need, cheaper than buying online for sure.
The only parts I had to buy were the sensor mount and to hook up the hose to the valve cover as had the tubing, couplers, beer keg(very low weight and easy to mod) filter, etc. I can help you with the parts selection, etc if needed.
My temp battery mount is very solid and passed track inspection, NASA, have to get an official inspection before going. I am going to build a removeable subwoofer and amp mount, tool storage, with washer bottle and pump for the windshield and will redo the battery mount when done, I would give away the one I made at that time. I am not sure when I will get to this though as have a ton of stuff more important to finish right now.
