Pictures from the Wrecking Yard

Last Friday, I headed out to U-Pull-It auto wrecking to see if they had any '92-'95 Civics on the lot. Fortunately they had three of them, so I took some pictures to see if it would help me with battery rack and other component placement.

You can click on any of the pictures for an enlarged version. I've limited the size to 640x480 to save disk space since there may be many photos during the course of this blog.

Here are some shots from Car #1:

This car had the whole front end cut off of it! Without the engine or transmission installed, I was able to see the components on the firewall more clearly.

Here's the trunk space. I got some approximate measurements from this.

Here's the pressure equalization flap on the left wall of the trunk that Bob Bath uses to vent the hydrogen gas from his trunk-mounted battery box.

Here's a shot under the car on the left side from the rear, just to the left of the spare tire well.

Here's a similar shot from the rear of the car but on the right underside of the spare tire well.

This shot is from the left side looking under the car at the middle of the spare tire well just behind the horizontal support member that ties into the swing arms of the rear suspension. The trunk battery box will need to sit between the two main support beams in the pictures above and behind this horizontal beam.

Another shot from the right side of the car looking up to where the fuel tank used to be in front of the spare tire well. This is just in front of the horizontal support beam that ties into the rear suspension.

A close-up of the right-front support beam in the engine compartment.

A close-up of the firewall. The master brake fluid distributor is in the middle of the picture. The firewall battery rack must not interfere with this.

A close-up of the drivers side support beam with the engine mount (right half of the picture).

Looking down at the power-steering unit with rubber booted linkage. Many people who convert their Civics replace this with a manual steering rack to get rid of the extra tubes and avoid having the power steering pump.

Okay, on to car #2: (slightly better shape)

Here's the engine compartment with most of the engine still installed.

This passenger-side firewall area is where the 12V battery used to sit. Notice the rust damage.

Here's a closeup of the driver-side engine mount. There might be some space in this nook to put something.

A look at the passenger-side nook just behind the right headlight with the main support beam. The front battery rack could bolt into this or hang off of it.

This is looking straight down on the passenger side just behind the radiator. Just right of center is the hydraulic clutch cylinder that often interferes with the front battery rack. I'm considering using a clutch-less adapter system from the motor to the transmission which would eliminate the clutch throw-out bearing and this cylinder, providing more space for the batteries.

Also looking straight down on the driver side just behind the radiator into another cavity that will hold the front battery rack.

This is the throttle assembly. The throttle cable is plainly seen in the center of the picture. Just behind the circular opening to the left is the Throttle Position Sensor (TPS) with red and yellow wires. To maintain the feel of the original accelerator cable, I'm considering making a circuit that can translate the resistance of the original TPS to the 5K resistor needed by typical EV motor controllers.

Going to the wrecking yard gave me a better feel for what I'm in for. Perhaps I'll have a field trip with interested members of the OEVA to look at these vehicles to plan the battery racks. Based on information from the CivicWithACord site, getting nine batteries to just fit in the trunk between the main support beams is going to be a challenge.

I might go back to U-Pull-It on Friday and try to remove the transmission from car #2 so I have something (albeit non-functional) to play with when considering adapter plates. At least I could try to get the throttle body and test out the position sensor (TPS).

Whew, enough pictures for one evening. Good Night.
