What drives the cost
- Battery capacity and source. New modules cost roughly twice as much per kWh as tested salvage modules.
- Motor output. Higher output drive units cost more and often require brake and suspension upgrades.

- Supporting systems. Charger, DC to DC converter, cooling, vacuum or electro hydraulic brakes, and heating.
Frequently asked questions
What is the cheapest way to convert a 911 to electric?
Use tested salvage modules, a smaller pack near the low end of the 140 mile band, and a verified Fitment Pack to minimize fabrication hours.
How many labor hours does a 911 conversion take?
Shops using the RESTOVOLT pack report 260 to 400 hours.
Does an electric 911 handle like the original?
With the split battery layout in the pack, reviewed builds achieve a more neutral balance than stock, though overall mass increases.
Is a 911 EV conversion reversible?
Yes. All structural mounts in this pack bolt to factory points so the original engine can return.
