I try to discuss my motor and battery trade offs at my site, so you will find that useful. I kept the transmision and clutch, which I highly recommend doing to get a good driving car. Please feel free to get in touch with me directly if you have questions. I'd be happy to help you in going through your design options.

Thanks, much appreciated. At this point, I've located a very cheap source for LiFePo4 cells, or at least they seem fairly cheap, so my plan is to go with 48 cells, making a total of 153.6 V/160 AH/24.58 KWH... seems like a good setup? I've run the calculator @ EVsource and brought the projected weight of the vehicle up to 2200lbs. to allow for the weight of the battery pack, motor, and other components. The calculator projects that at 80% DOD, I'd get around 89.37 miles per charge. Does this seem correct to you? Thanks for the input!
