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.

Info about JDM vs USDM y21 or s80 transmission

There are many differences between the JDM and USDM transmissions on Honda b-series engines. Here are some of the things I discovered while rebuilding several transmissions.

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.

Quick junk yard Transmission pull

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.

Changing from Cable to Electric VSS

Cable VSS
Cable Vehicle Speed Sensor

My car (1988 CRX HF) came stock with a Cable VSS (Vehicle speed sensor) on the transmission. The engine is a swap (b16a sir2, y21 transmission w/lsd) and was still using the cable VSS. After I installed the Integra cluster in the CRX, I needed to convert the car to Electric VSS.
