We decided we wanted to make a sign for our Swap Meet sale. We wanted to keep with the DIY spirit of howtoengineering.com so we used Wood, Metal, and Tiles for our company sign.
I will soon be selling hand crafted items at the local flea markets, swap meets, and art shows. I needed a display cabinet, so I made my own!
I started using a piece of cardboard between my battery and the intake a few years ago, and it seemed to gave me about a 2 miles per gallon increase. (Though after building this, I received criticism that this will not help with gas mileage, but will help with performance!)
Now it was time for me to relocate my battery so now I have to make a Hot air block from scratch.
I made this one from metal, and I expect better performance than my cardboard version.
This is the finished hot air block and my new battery box
I was using the stock battery mount location, with a normal tie down, but it kept having issues and getting loose.
So then bought a replacement tie down, but that also came loose.
I wanted to relocate the battery to the trunk, but I have way too many wires added in over time (inverter, fuel pump, 2x amps, and more). So I decided to relocate to about the same area under the hood, but lower and out of the way.
I have a b16 SIR2 that came with a y21 LSD transmission, but the case leaked and I replaced it with a more common s80 about 2 years ago when I rebuilt it.
I added carbon lined synchros, new bearings, new rubber, new gaskets, measured and replaced as need, full rebuild.
I was driving on the freeway about a year ago and a piece of plate steel was pulled up by the wind, and busted a hole in my s80 transmission case.
This is an article about how I got a replacement housing from the junk yard.
