Do you have any recommendations for a transmission? I'm thinking that I will be taking this out onto the highway/freeway for my commute and would like to have an overdrive capability along with a fast first & second gear. I was thinking about the Corvette C5 or Z06 6-speed transmission, but is there a cheaper easier option? My wife can't / won't drive a manual so I was thinking about leveraging their paddle shifters.
Well the transmission tunnel approach is not really expensive but requires a lot of sheet metal bending and cutting and welding skill.
You could put a motor and TH400 transmission in the front of the car, but again you would be fabbing up a lot of custom motor mounts and really taking a sawsall to the unibody and rewelding the strength back in.
For a daily commuter I would start by scanning through EVALBUM.COM and search on Fiero. There must be a hundred in there. Look for builds that give the same performance you are looking for.

With twin Warp9's I don't think you need the gear vendors overdrive. I don't even kick mine in until about 70mph. However, with a single Warp9 or Warp11 you may consider it. You may want to consider a large Warp11 into the stock Fiero Transaxle with a lenco gear reducer flipped around to make a permanent overdrive. This would give peak power around 5000rpm, be a reasonable 300ftlbs of peak torque and be able to run all the standard transaxle transmission functions.(This is a new idea I am afraid but I think quite doable.

I would stay away from the LiPo's for daily driver. The claimed cycles on them is around 300. I am near 180 but that race driven cycles. I am afraid fi you drove every day and the cycle life truly is only 300 that you would be replacing a pack a year. I will let you know more when I pass 300 cycles if they have more due to proper balance and management.
