Choosing Your Donor Classic: Not All Cars Are Created Equal
Ah, the crucial first step!
Picking the right classic car for your EV conversion is like choosing a dance partner.
Some cars are naturally better suited for the tango, while others are destined for a clumsy waltz.
Here’s what to look for:
Space, glorious space: This is paramount.
You need room for batteries, batteries, and more batteries.
Think about vehicles with large engine bays or trunks that can accommodate significant battery weight.
SUVs, trucks, and larger sedans from the 60s and 70s often make great candidates.
VW Buses and Beetles, surprisingly, are also popular due to their unique layouts.
Weight: Lighter cars generally perform better with less power.
However, you'll be adding significant weight with batteries, so consider a car with a robust chassis that can handle it.
Simplicity: Older cars with simpler mechanical systems are often easier to convert.
Think manual transmissions (which you'll often retain and mate directly to the electric motor) and fewer complex electronic systems to contend with.
Rust: This is your arch-nemesis.
A rusty car is a money pit, regardless of the powertrain.
Ensure the body and frame are solid.
Popularity & Parts Availability: Choosing a popular classic means easier access to replacement parts for the non-EV bits (suspension, brakes, interior, etc.).
Cars like classic Mustangs, Camaros, VW Beetles/Buses, and even older Volvo or Mercedes models are good bets.
For my personal project, I chose a 1974 VW Type 2 Bus.
Why?
Because it's a rolling brick with tons of space, a relatively simple drivetrain, and an undeniable charm.
Plus, the flat load floor made battery placement a bit easier.
It was a perfect canvas for an EV transformation.

The Essential Components of a Classic Car EV Conversion
Alright, let's get down to the nuts and bolts – or rather, the motors and batteries!
Understanding these core components is crucial before you even think about lifting a wrench.
Electric Motor: The New Heartbeat
This is where the magic happens.
Electric motors deliver instant torque, meaning your classic will feel surprisingly zippy off the line.
You'll typically choose between AC (Alternating Current) and DC (Direct Current) motors.
AC motors (like those found in Teslas) are generally more efficient, offer regenerative braking, and are becoming the standard.
DC motors are often simpler, cheaper, and easier to install for DIYers, but they're less efficient and lack regen braking.
For my VW Bus, I opted for an AC motor, specifically a NetGain Hyper9, due to its efficiency and the ability to integrate regenerative braking, which is a game-changer for range.
Battery Pack: Fueling Your Future
This is your "fuel tank" and arguably the most expensive part of the conversion.
Lithium-ion batteries, particularly those from electric vehicles like Nissan Leafs or Tesla Model S/3, are the go-to choice due to their energy density and cycle life.
The size of your battery pack determines your range.
More kWh (kilowatt-hours) equals more miles.
But remember, more batteries also mean more weight and more space required.
It's a delicate balancing act.
For the Bus, I aimed for a respectable 40 kWh pack, cobbled together from several Nissan Leaf modules, giving it an estimated range of about 100-120 miles – perfect for local cruising and weekend adventures.
Motor Controller: The Brains of the Operation
Think of the motor controller as the engine's ECU.
It takes your accelerator pedal input and translates it into instructions for the motor, regulating power output and speed.
It’s a crucial piece of high-voltage electronics.
Matching the controller to your chosen motor is vital for performance and safety.
Battery Management System (BMS): Your Battery's Best Friend
This is non-negotiable for lithium-ion batteries.
A BMS monitors the voltage, temperature, and current of each individual battery cell, ensuring they charge and discharge safely and evenly.
Without a proper BMS, you risk cell imbalance, reduced battery life, and even thermal runaway (i.e., a very bad day).
Never, ever skimp on the BMS.
Charger: Rejuvinating Your Ride
You’ll need an on-board charger to convert AC power from your wall outlet into DC power for your battery pack.
The charger's power rating (kW) determines how quickly your car charges.
You can also integrate a DC fast charging port (CCS or CHAdeMO), but this adds significant complexity and cost.
DC-DC Converter: Keeping the Lights On
Your main battery pack operates at high voltage (e.g., 100-400V), but your classic car's original electrical system runs on 12V (for headlights, radio, wipers, etc.).
The DC-DC converter steps down the high voltage to 12V, effectively replacing your alternator.
Electric Vacuum Pump: Because You Still Need Brakes!
Most older cars use engine vacuum to power their brake booster.
Since your electric motor doesn't produce vacuum, you'll need an electric vacuum pump to maintain brake assist.
Don't forget this critical safety component!
Heating and Cooling: Comfort in All Seasons
The original heater core relied on engine heat.
For an EV, you'll need an electric heater, which can be a significant draw on your battery, affecting range.
Air conditioning will also need an electric compressor.
These are often considered "Phase 2" items for budget-conscious builds, but crucial for daily drivability.

Sourcing Components: Where to Find Your Electric Gold
This is where the treasure hunt begins!
Sourcing reliable components is key to a successful and safe conversion.
You have a few options, each with its pros and cons:
1. Dedicated EV Conversion Parts Suppliers:
These companies specialize in components specifically designed for EV conversions.
They often offer complete kits or individual components like motors, controllers, and battery modules with good support.
While often more expensive, you get peace of mind and technical assistance.
I highly recommend checking out companies like EV West or Electric GT.
They have been pivotal in building the EV conversion community and offer fantastic resources.
2. Salvage Yards and Wrecked EVs:
This is where you can find great deals, but it requires more expertise.
Wrecked Nissan Leafs, Teslas, Chevy Bolts, or even older electric forklifts can be excellent sources for motors, battery modules, and other high-voltage components.
Be extremely cautious when handling high-voltage components from salvage vehicles, and always consult with experts or take appropriate safety precautions.
A good resource for finding salvage parts is a site like Copart or other local automotive salvage yards.
3. Online Marketplaces and Forums:
Websites like eBay, specialized EV forums, and even Facebook Marketplace can yield surprising finds.
Just be sure to do your due diligence, verify the seller's reputation, and understand exactly what you're buying.
The "DIY Electric Car Forums" (often hosted on sites like Endless-Sphere for e-bikes, but with sections for EV cars) are great for advice and sometimes for buying/selling components from fellow enthusiasts.
Join the DIY Electric Car Forum!
When sourcing, always prioritize safety and compatibility.
Don't be afraid to ask questions from suppliers or experienced builders.
It's better to spend a bit more upfront for quality and reliability than to deal with issues down the road.

Detailed Build Log: My Journey Electrifying a 1974 VW Bus
Alright, let's pull back the curtain and show you how it all came together for my beloved 1974 VW Bus, affectionately named "Voltzwagen."
This wasn't just a project; it was an obsession, a learning curve, and ultimately, a triumph!
I'm not going to lie, there were moments I wanted to throw a wrench across the garage, but the satisfaction of the first silent drive made every single skinned knuckle worth it.
Phase 1: Planning and Prep – The Dream Begins
This is arguably the most critical phase, yet often overlooked by eager beavers.
Before any wrenches touched the Bus, I spent months researching.
I devoured every book, forum post, and YouTube video on EV conversions.
I drew schematics, calculated range estimates, and meticulously planned battery placement.
The goal was a usable range of at least 80-100 miles, good acceleration for city driving, and most importantly, safety.
I decided on a NetGain Hyper9 AC motor, due to its compact size and efficiency, mated to the original VW Bus manual transmission via an adapter plate.
For batteries, I went with used Nissan Leaf modules (gen 1, 24 kWh modules are quite affordable now) which I sourced from a reputable dismantler.
The plan was to build a 40 kWh pack (roughly 16 modules) to achieve the desired range.
I also purchased a reputable EV control system kit that included the motor controller, BMS, and various high-voltage contactors.
Mapping out where every single component would go – the motor, controller, charger, batteries, vacuum pump – was like playing a high-stakes game of Tetris.
I measured, re-measured, and then measured again.
This planning saved me countless headaches down the line.
Phase 2: Drivetrain Removal – Out with the Old
This was the fun, messy part!
The Bus’s original air-cooled engine, a clunky 1.8L beast, along with its fuel tank, exhaust, and associated plumbing, had to go.
This process felt a bit like performing open-heart surgery on a very old, very beloved patient.
I carefully labeled every wire and hose, even though most wouldn't be reused, just for good measure.
The engine came out surprisingly easily once everything was disconnected.
The fuel tank removal was a bit more delicate, requiring careful draining and ventilation to avoid any explosive surprises.
Once everything was out, I thoroughly cleaned the engine bay and undercarriage, removing decades of oil, grease, and grime.
This provided a clean canvas for the new electric components and made identifying potential issues (like hidden rust) much easier.
Phase 3: Motor Mounting – The New Core
With the old engine bay clear, it was time for the new heart.
The Hyper9 motor came with a standardized faceplate, but mating it to the VW transaxle required a custom adapter plate.
I purchased a pre-fabricated adapter from an EV conversion specialist, which saved me a huge amount of fabrication time and ensured perfect alignment.
The motor mounted directly to the transmission input shaft, replacing the original engine.
This maintained the use of the original manual transmission, allowing me to still shift gears (though in practice, you rarely need more than 2nd or 3rd gear with the electric motor's wide powerband).
Custom motor mounts were fabricated to securely hold the motor in place, ensuring it could handle the instant torque without undue stress on the chassis.
This was a critical step for both performance and safety.
Phase 4: Battery Placement – Strategic Power Packing
This was perhaps the most challenging aspect: finding safe, balanced, and accessible locations for 40 kWh of battery modules.
I decided on a distributed approach.
Some modules went into the original engine bay, cleverly packaged around the motor.
Others were placed under the rear bench seat, and a few more in custom-fabricated boxes in the front "frunk" (front trunk, where the spare tire usually lives).
Each battery box was custom-built from strong, insulated material, with proper ventilation and fuse protection.
Weight distribution was paramount.
I aimed to keep the center of gravity low and central to maintain the Bus's notoriously stable (or unstable, depending on your perspective) handling characteristics.
This involved a lot of test fitting, measuring, and re-measuring.
Securing the batteries rigidly was also crucial for safety in the event of a collision.
Phase 5: Wiring and Electronics – The Nervous System
This is where things get serious, and where an understanding of electrical safety is non-negotiable.
High-voltage wiring (the orange cables!) needs to be routed carefully, securely, and away from sharp edges or potential pinch points.
I installed a robust BMS to monitor each of the 16 battery modules, ensuring proper balancing and preventing overcharge or over-discharge.
The motor controller was mounted securely in the engine bay, with heavy-gauge cables running to the motor and battery pack.
The DC-DC converter was wired to step down the high voltage to the Bus's original 12V system, powering lights, radio, and wipers.
I also installed an electric vacuum pump for the brakes and an electric heater for the cabin.
All connections were crimped, soldered, and heat-shrunk with obsessive care.
I used appropriate high-voltage disconnects and fuses at key points for safety during maintenance and in case of a fault.
Every wire was clearly labeled.
Trust me, future you will thank present you for doing this.
Phase 6: Testing and Tuning – First Spark, First Drive
This phase was a mix of pure terror and utter exhilaration.
After double-checking every connection (and then triple-checking it), it was time for the moment of truth.
I started with low-voltage tests, verifying all the 12V systems worked.
Then, with a fire extinguisher at hand and a buddy standing by, I carefully energized the high-voltage system.
No smoke! Always a good sign.
The motor controller diagnostic software allowed me to calibrate the accelerator pedal, monitor battery health, and run initial motor tests.
The first time the motor whirred to life, silent and powerful, was an unforgettable moment.
The initial "test drive" was literally just rolling it a few feet out of the garage and back.
Then, a slow crawl around the block, listening for any strange noises, checking gauges, and ensuring everything felt right.
The regenerative braking was particularly satisfying to feel working.
Phase 7: Final Touches and Road Testing – The Sweet Reward
With the core system functioning, it was time for the finishing touches.
This involved fabricating covers for the exposed battery boxes, installing proper charging ports (I used a J1772 standard port), and integrating a new digital dashboard display to show crucial EV metrics like battery state of charge, motor temperature, and current draw.
I also updated the suspension to handle the added weight of the batteries, ensuring a safe and comfortable ride.
Finally, extensive road testing began.
This involved driving in various conditions – city streets, highway, hills – to gather real-world data on range, performance, and charging times.
It was incredible to drive "Voltzwagen" silently, feeling its instant torque and knowing that I had transformed a gas-guzzling classic into a clean, modern machine.
The smiles, waves, and inquisitive questions from passersby were just the cherry on top.
Every mile was a testament to the hard work and dedication poured into this amazing project.
