I haven't been totally lax, though, and a few things have happened with the conversion. I've removed the power steering rack (in preparation for replacing it with a manual one), degreased the transmission, and dropped the sub-frame. I've also done some initial scoping of space for battery boxes.
Transmission:
Before..... it's the oil-covered appendage hanging down from the engine in this view.
Sub-frame:
On these Saturns, there's a sub-frame located on the bottom of the engine compartment which bolts to the main frame of the car and supports, among other things, the front sway bar, steering rack, and radiator. I decided to take it out of the car for a couple of reasons: 1) they tend to rust out and I wanted to make sure it's sound (while in the car it was hard to tell because most of it was also covered with grungy oil), and 2) the front cross-beam where the radiator mounts sits just a little bit too high in the engine compartment to allow me to place batteries where the radiator used to reside. With my current plan of using 13 12-volt batteries, at least 3 of them need to fit in the engine compartment (if I could fit 5 or 6 it would be better for the weight distribution!); there's not room in there with the sub-frame in its current form.
Battery boxes:
My original idea was to put as many batteries as would fit in the engine compartment and put the balance in the back seat area. Other Saturn conversions have had as many as 5 batteries in the engine compartment, but none of them were actually enclosed in insulated boxes (a necessity if this car is going to be suitable for winter commuters) and were smaller format batteries. On paper (well, ok, my computer screen) it seems to me that I will be hard-pressed to be able to fit 3 batteries (they are monster size) along the front and still leave room for the motor controller, cabin heater, vacuum pump and accumulator, and the various contactors/relays/potbox/etc. And it looks like lowering the sub-frame cross-beam will help.
So, the current plan is to put 3-4 batteries in front, 6 where the back seat was, and the balance in the spare tire well. I'm not keen about having batteries behind the rear axle, but I don't see a way to fit them forward of the axle without major surgery on the underbody sheet metal.
Next steps: order the conversion kit and mock up battery boxes.
