I am contemplating rebuilding this car using an EV Conversion Kit. This car as you know has a 3.8 SIII Base engine and 4T65E enhanced M15 transmission. The HP and torque are about 205. What are the possible EV Conversion Kits that could be suitable for this project?

Normally when people say EV swap they want to remove the engine and transmission and put in an electric motor and torque box. If this is the case, then you just need to find a kit that includes a motor able to handle the weight of the vehicle. The options are endless for this as your only limitations are going to be mounting these components and then getting axles that will connect to your half shafts so that the torque can be transferred to the wheels.

Here is a link to a popular kit:

However, taking an existing vehicle that does not have a kit made specifically for it introduces all sorts of hurdles as you will have to come up with the mounting of all the components, placement, and connection of the torque box to the axles on your own. It can be done but the generic kits do not include this so it is left to you.

Please let us know if you have other questions.

Okay thanks for the link. It says 35 HP continuous and 150 HP peak (26 TO 105 kwh). I am not sure how that compares to the combustion 3.8L 205 HP engine this 3500 pounds Pontiac has. Since the ICE has somewhere around 20% efficiency, I am assuming this type of motor would be good? Yes, mounting will be a challenge as well. Thanks for your help.

Keep in mind the HP of an EV kit is pretty much directly to the wheels. So it is 35 HP in low torque situations and can be up to 150 HP when you go to wide open throttle.

This HP goes through the torque box and to the wheels but is much more responsive and efficient then a gasoline powered vehicle.
