After creating the torsion bar mounts on the end of the VW Bug frame rails, I bolted up the Toyota MR2 torsion bars. I have also clamped the frame rails on the plywood template to be positioned between the front and rear suspension.
Now that I know where the VW Bug main frame rails will be, I am creating the MR2 rear torque bar mounts in the end of the rail tubing.
Creation of the VW Bug frame starts with determination of where and how the frame member will be positioned around the engine. I have very limited space around the Toyota MR2 3SGTE motor. My plan is to create a plate type frame that travels straight through the rear of the vehicle. I started with some small boards glued together to determine the lower profile of the plate so I can trace that profile on to a piece of foam board.
This video shows where the VW Bug main frame rails will terminate at the Toyota MR2 anti-torsion bars attached to the lower rear control arms.
I am placing the basket material (constructed earlier) over the Toyota MR2 3SGTE motor. This gives me a good idea where everything will sit under the VW Bug body. I need this info to start the initial frame planning.
The initial frame plan can start, now that I have the VW Bug’s drive train in place. As you can see I have finished the alignment of the Toyota MR2 3SGTE motor. I have both struts in place as well as the motor mounts and all the accessories (starter and AC unit etc.). Oh and the shop crane has been removed.
I now have the MR2 3SGTE rear cross-member installed as well as tying in all the suspension components. The two lower control arms and the two rear control linkages attach to the cross-member. This is a tight fit under the VW Bug body.
In this video you have to look for the changes. The engine is tilted back at the correct angle for the Toyota MR2 3SGTE engine. I also have blocks supporting the engine from below (no weight on the chains of the shop crane). I still need to install the rear cross-member to get everything exactly where it needs to be in the VW Bug rear end.
The VW Bug rear end assembly continues with the addition of the Toyota MR2 3SGTE driver side rear drive axle and wheel. Some initial alignment has also been completed.
After installing the MR2 passenger drive axle, I can now bolt the wheel on. The wheel will sit in the wooden box for the VW bug rear end alignment.
