How I make my own hot air blocking panel for intake air filter.
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

How I make my own car battery box with tie down.
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.

How to swap transmission oil fill bung – JDM vs USDM
2 years ago I bought a s80 case (USDM) when I rebuilt my y21 JDM transmission, because of cracks in the y21 housing.
Then after 1 year of use, a metal plate on the freeway hit my transmission and caused a hole.
The aluminum was brittle and filled with stress cracks in the housing, so when I TIG welded the hole, it caused issues.
I decided to go to the junk yard and get a s80 case from an integra. I found a 1995 3 door RS 5spd and pulled the transmission. (read about it here)
I did not know it at the time, but after I got home, I found it impossible to find a large oil cap.
I tried Honda and Acura dealers, and even used JDM engine suppliers, but no one had any for sale.
The USDM 1994-1995 Honda Del Sol VTEC model is the only USDM car with that oil cap. The part is discontinued and not available.
I needed a way to cap my new rebuild, so I tried to change the breather vent tube (oil fill hole) from the USDM s80 case to the JDM s80 case.
