Building custom cars in my backyard

The VW bug rear engine cage is now complete. I have positioned and welded on the two rear angle members as far as I can get them until the frame is removed from the MR2 3SGTE motor to weld the back side. I angled these two pieces opposite the front fire-wall to try and give [...]

I need to install a couple of angle braces in the VW's rear engine cage similar to the front fire-wall. I again used the foam board to get the correct size and shape of these two framing pieces. I now have both units cut to fit, so all I have to do is position them [...]

With both VW bug rear engine cage members tacked in place, I removed all the bracing and finished welding everything I can get to for now. I will finish welding behind the cage when I remove the frame from the MR2 3SGTE engine later.

With the 1st Toyota MR2 3SGTE engine cage member in place, I need to position the 2nd. These two members are the same size and need to be exactly parallel to each other as well as square to the VW bug frame plates. After determining the location of the 2nd member, I cut a couple [...]

I am using the same 1.5x1.5 inch square tubing for the VW bug's rear engine cage. This process took awhile to get the first member cut to fit and aligned. I used one of my long bar clamps to bind the rear engine plate frames together to hold the piece in place for welding.

With the basics of the VW bug front fire-wall complete, I can now focus on the rear engine cage bracing. The rear engine cage will be similar to the front fire-wall but it will be built to fit it's location. This cage needs to be really strong to contain the MR2 3SGTE stroker motor.

Using the foam template I created the steel pieces to fit between the upper and lower fire-wall members. I then clamped them in place and welded them on. I completed the welding on the front side of each joint because I will be fitting a fire-wall plate on top of these joints.

To add frame support and triangulation, I will incorporate two angle pieces into the VW bug's fire-wall. I have set the fuel cell in place to try and determine where these supports should be located.

With the VW bug's lower rear fire-wall member tacked in place, I need to construct the upper fire-wall member. I used the same 1.5x1.5 inch 10 ga. tubing and cut a piece to fit. I tapered the corners a bit to match the angles of the plate fame before welding it in.

With the VW bug's lower rear fire-wall member built, I have reinstalled it and tack welded it in. Everything is now bolted together and all 4 MR2 3SGTE motor mounts are in place. All I have to do now is complete the fire wall and rear engine cage bracing.
