It is the system designed for your vehicle’s layout, with compatible mounts, controls and installation support—and with a clear list of what you still need to supply. “Electric crate motor” can mean anything from a compact motor-and-controller unit to a vehicle-specific conversion package, so compare fitment and included hardware before comparing output.
What does “electric crate motor” mean?
It is a marketing term, not a standard package definition. A product may be a compact motor with its controller and battery integrated, a transverse e-axle, a motor-and-inverter assembly intended to work with a retained transmission, or a vehicle-specific conversion system. Those options involve very different amounts of fabrication and electrical work.
Before treating any product as a drop-in, check the exact chassis and year, available space, mount points, transmission plan, and the motor’s output interface—such as a driveshaft flange or axle. Also ask how the kit gets into the vehicle and what installation support is available. A fitment claim for one chassis does not establish compatibility with another.
How the options compare
This is a fit-and-scope comparison, not an independently tested performance ranking. Specifications and product details below are manufacturer-published; confirm current configuration and availability with the seller.

All output figures in the table are product specifications or company-published claims, not results from a common test. Peak power is not continuous power: where a continuous rating is not given, do not assume the peak figure can be sustained. Compare torque, gearing, vehicle weight, intended duty and drive layout alongside power.
Which systems are most likely to make a swap easier?
For a vehicle-specific classic-car conversion: Electrogenic USA
Electrogenic describes complete drop-in kits for classic-car conversions, installed by its worldwide partner installers, and lists vehicle-specific offerings including Jaguar E-Type, Land Rover, Mini and DeLorean. That makes it the clearest fit in this group for a buyer who wants a package and installation route tailored to a particular model, rather than a generic motor assembly. Confirm that your exact vehicle is covered and ask the installer what the kit includes. Electrogenic says it acquired the TREMEC ElectricGT business in July 2026, so verify the current product name, support contact and installer for any kit associated with that lineage.

For a bolt-in cradle with a defined parts list: E-Muscle Cars EMC300
The EMC300 listing describes a 400 V drivetrain with a BorgWarner iM225 integrated motor and inverter, a single-speed gearbox with a 1410 flange yoke, an AEM motor controller/VCU, wiring harnesses and high-voltage DC leads. Its bolt-in cradle addresses one part of installation, but it is not a complete vehicle conversion kit: the listing explicitly excludes batteries, charger, high-voltage contactors, fuse/relay box and cooling system. Custom frame-side motor mounts are available for many chassis by inquiry, which means buyers should confirm their specific frame before relying on the supplied cradle. The displayed price and configuration can change. See the EMC300 product listing
For a transverse layout: Swindon Powertrain HPD E
The HPD E is an e-axle range, not simply a longitudinal motor designed to replace an engine while retaining the original driveline. Both listed versions use single-speed helical gearing; the product page also lists 97% maximum motor efficiency. Optional components include motor/transmission mounting kits, driveshaft joint housings, a limited-slip differential, DC-DC converter/on-board charger, speed sensor, coolant pump, inverter systems, throttle pedal and gear selector. Those options can help assemble a system, but they do not establish that the e-axle will fit a particular car. Check packaging, axle geometry and the proposed layout against the target vehicle.

For a small engine replacement: Death to Gasoline DropIN 72V
This is a genuinely integrated option for small vehicles and equipment, not a candidate for a conventional full-size car swap. Death to Gasoline says the motor, controller and battery form one unit, and describes the product as “plug and play” with no soldering or coding required. The company says bolt placement matches the BASE 50 engine, gives other mounting points, and advises customers to consult its supported-chassis table. It also describes right- or left-hand-drive orientation and horizontal or vertical placement. Verify the specific chassis and mounting arrangement rather than relying on the broad fit description. Death to Gasoline product information and FAQ
For a small-block-style housing: Webb Motorworks Cyber Beast
Webb Motorworks markets the Cyber Beast as an electric motor concealed in a small-block-style housing, claiming stock engine and transmission mount patterns, a 1.9 reduction, and bench testing and programming. Those are vendor claims, not independently verified fitment or test results. The company says the buyer must connect the throttle, radiator hoses, low-voltage wiring, controller and charging port. The page reviewed does not provide a current price or a complete itemized bill of materials, so request a written parts list and vehicle-specific fitment confirmation before comparing its price or installation burden with a more fully specified kit.

For selected classics with a retained manual transmission: APP EV Systems
APP EV Systems describes bolt-in systems for selected classic cars, using vehicle scanning and CAD replication, calibrated electronics and retention of the factory manual transmission. It also discusses charging and dual cooling loops. The company advertises modular packs up to 73 kWh and approximately 250 miles of range; these are company-published claims, not independent range-test results. Its page showed the first production G-body 911 kit installation and said a review video was still anticipated, so that statement alone does not establish a long installation track record. Ask which exact model and transmission configurations are supported and what battery and cooling hardware the quoted system includes. APP EV Systems conversion-kit information
For historical context, not an assumed current purchase: Chevrolet Performance eCrate
A Chevrolet Performance flyer hosted by Lingenfelter describes a three-phase permanent-magnet 400 V motor designed to connect to a GM four-speed automatic and a standard GM crate transmission, plus a liquid-cooled system and a 66 kWh/400 V battery option. The flyer said limited quantities were expected from mid-2023; that historical notice does not confirm current stock or orderability. It also describes CARB Executive Order coverage for specified model-year 2000-and-older light-duty vehicles at a GVWR of no more than 6,000 lb. Treat that as a lead to verify, not a blanket legality guarantee: check the current order and your vehicle’s eligibility with the relevant authority or qualified installer.

What must be included for a conversion to be complete?
A motor kit alone does not make a complete EV conversion. The battery has to fit the vehicle and supply the system’s voltage and power needs; charging, high-voltage protection, wiring and thermal management also have to be addressed. The motor’s cooling requirements and the battery’s cooling needs may differ, so ask how both are handled.
- Drive hardware: motor, inverter, controller, gearbox or e-axle, mounts, output flange or axle interface, and any driveshaft components.
- High-voltage system: battery pack, contactors, fuses, service disconnects, high-voltage cabling and charging equipment.
- Vehicle integration: throttle and selector, low-voltage harnesses, battery management, DC-DC conversion, instrumentation and any required controls.
- Thermal management: pumps, radiators, hoses and cooling circuits required by the motor, inverter and battery.
- Installation scope: supplied brackets versus custom mounts, fabrication, wiring work, commissioning and access to qualified support.
Ask the seller to mark each item as included, optional, buyer-supplied or not applicable in a written bill of materials. This also helps expose the whole-project cost: a lower-priced motor package may leave the buyer to source expensive battery and balance-of-system hardware separately.
How to choose for your vehicle
- Define the vehicle and use. Record year, make, model, chassis, curb weight, intended street or competition use, and desired performance. Ask the manufacturer to confirm fitment for that exact configuration.
- Choose the driveline layout. Decide whether to retain a transmission, replace the engine and transmission, or use a transverse e-axle. Check mount points, available space, driveshaft or axle geometry, gearing and clearances.
- Compare usable output. Look for continuous as well as peak power, torque, motor speed and reduction. Match them to vehicle weight and duty rather than choosing by peak horsepower alone.
- Get the complete bill of materials. Identify included, optional and missing components across the motor, battery, charger, high-voltage protection, controls and cooling system.
- Price the installed project. Include batteries and other omitted hardware, fabrication, installation, commissioning and any changes needed to the vehicle. Confirm warranty terms and support coverage directly with the seller.
- Check local rules before buying. Registration, inspection and emissions requirements depend on jurisdiction, vehicle and installation details. Confirm requirements with the relevant authority or a qualified installer.
For fitment, warranty, installer availability and current orderability, the manufacturer or seller is the authoritative contact; the product pages cited here do not establish all of those terms for every vehicle or region.
