Classic Car EV Conversion Cost: Kits, Installed Conversions And Complete Cars
The references listed below support the regulatory, safety, and manufacturer statements in this guide. Any dollar figure is an editorial planning estimate based on typical scope, not a quote and not taken from those references, unless a current official price is explicitly cited at that point in the text. Confirm fitment, safety, legality, availability, and current pricing for your exact vehicle before you buy or commission work.
A classic EV conversion can be sold as parts, as conversion work on a vehicle, or as a complete rebuilt car. Those prices describe different purchases. The motor alone does not account for battery packaging, charging, controls, fabrication, braking support, heating or commissioning.
The supplier prices below were checked September 28, 2026. They are published offers, not completed-project averages. Start with the EV conversion directory and ask for a bill of materials and an installed scope for your exact car.
Published Prices With Their Scope
| Provider and offer | Published USD price | Key boundary |
|---|---|---|
| EV West Universal Hyper 9 120V package | $6,174 | A listed motor/inverter package with supporting items, not a complete converted car |
| EV West 1956–77 Beetle conversion kit | $22,414.74 | A model-specific kit listed with battery packs; installation and donor remain separate |
| Moment Motor BMW 2002 Signature conversion | From $85,000 plus vehicle cost | A provider's defined conversion program; obtain restoration and option inclusions |
| Moment Motor Porsche 911 Signature conversion | From $125,000 plus vehicle cost | A conversion starting price, not a purchased donor and finished restoration total |
| Kindred EV 911 | $349,000 listed | A complete vehicle program; request the current purchase specification |
These are not interchangeable quotes. A generic drivetrain package cannot be installed simply by adding the difference between it and a model-specific kit. Read the itemized contents, application and battery choices. Freight, tax, donor repairs, options and outside work should be explicitly addressed in the proposal.
Batteries And Packaging Come Before A Range Promise
Tell the converter the journeys you need to make, including speed, hills, weather, passengers and luggage. Ask how its range estimate was derived and whether it comes from a comparable completed car or a design calculation. A supplier's advertised range is not an independent test of your future build.
Request battery capacity, enclosure locations, usable luggage space, axle weights and service access. A large battery can affect the car's weight and packaging; the right answer needs a vehicle-specific design. Ask which battery components are new or reused, how their condition is assessed and what support remains available later.
Charging also needs a specification: connector, AC charging capability, any DC charging provision and the equipment required where you park. Do not assume a kit includes rapid charging because the donor electric vehicle used it. Ask how charging status, faults and isolation checks are displayed and serviced.
The Installed Scope To Request
| System | What belongs in the written scope |
|---|---|
| Donor condition | Structural inspection, corrosion repair, running gear and body/interior work |
| Drivetrain | Motor, reduction or retained transmission, mounts, shafts and control integration |
| Battery system | Modules, enclosures, management, protection, mounting and cooling design |
| Charging and low-voltage power | Charge hardware, inlet, DC-DC supply, wiring and instrumentation |
| Road use and comfort | Brake and steering assistance, heating, demisting and air conditioning |
| Commissioning | Weight and clearance checks, fault handling, testing and owner documentation |
| Future support | Replacement parts, diagnostic access, warranty scope and service arrangements |
High-voltage work needs a qualified conversion specialist. This guide is for specifying and comparing a project; it does not provide instructions for assembling or energizing a battery system.
Parts Supplier And Conversion Shop Are Different Roles
EV West's directory profile is supported by its published parts and conversion information. Its kit catalog establishes product scope; confirm whether the business is quoting your installation itself or supplying components for another installer. Do not read a stocked kit as an available workshop slot.
Moment Motor's Signature Line gives model-specific conversion examples. Its price is explicitly additional to the vehicle. Ask whether the proposed donor needs separate restoration before conversion and who is responsible for that work. Kindred's model listing provides a complete-vehicle comparison, so the donor and restoration boundary must be established before comparing totals.
A Budget Worksheet For Your Car
Begin with donor acquisition or your existing car's assessment. Add body and chassis repairs, the agreed conversion package, excluded integration work, interior/HVAC changes and completion costs. Keep delivery, tax and registration-related expenses visible as separate lines. Confirm the local inspection and registration path with the relevant authority for your vehicle; a supplier's past project does not decide it.
If a proposal contains an allowance, ask what it covers and how an overrun is approved. For a hypothetical arithmetic example, an assumed 20 additional fabrication hours at $150 per hour add $3,000. That example is not an estimate of the labor normally needed for an EV conversion.
Use the restomod budget guide for the wider rebuild and the editable brief to document range needs, charging access and must-keep features. Compare at least the donor, battery, installation and aftercare boundaries before choosing between offers.
