Our EV Miata Starter Kit was designed to be safe, easy to install, and flexible enough to support a variety of available components and battery chemistries.

Safety requirements

  • Steel battery racks are bolted to the vehicle's frame rails and are designed to secure the batteries in the event of an impact
  • Fully insulated high voltage terminals keep wandering fingers from coming in contact with pack voltage
  • Both battery options are sealed to reduce or eliminate the possibility of spills of damaging or toxic electrolyte

Ease of installation requirements

  • No welding required
  • Minimal "heavy" work - the engine needs to be removed, but the transmission and rear sub-frame do not
  • Common hand and power tools used throughout
  • Clear, step-by-step instructions with illustrations

Flexibility requirements

  • Support for inexpensive lead-acid absorbent glass mat (AGM) and light weight lithium (LiFePO) batteries
  • Size the battery racks to support a variety of lithium cell brands and amp ratings
  • Support for AC and DC motors up to 9 1/4" without modification - 11" motors can be accommodated with custom components
  • Support for a variety of controller brands and models - Curtis, Zilla, NetGain, Evnetics, etc.
  • Support for a variety of Chargers - Zivan, Manzanita, Elcon, etc.

Battery Rack

  1. The Nose Rack sits in the nose of the car and holds 4 Group 34 AGM batteries, or a number of LiFePO cells.
  2. The Top Rack sits above the motor and holds 4 Group 34 AGM batteries, or a number of LiFePO cells. It also provides the mounting points for the vacuum pump, DC/DC converter and High Voltage Enclosure bracket.
  3. The Trunk Rack sits below the trunk floor so that trunk space is optimized. The Trunk Rack holds 5 Group 34 AGM batteries, or a number of LiFePO cells.

Mounts and Brackets

  1. The Motor Mounts firmly mounts the motor (AC or DC)  to the front sub-frame.
  2. The Controller mounts on the Controller/Charger bracket above the Nose Rack and will support a number of different controller options. This bracket allows for 6" of hood clearance toward the forward edge and 8" of clearance at the rear. The bracket is 28.75" wide and 10.75" long. This bracket will provide a secure mounting point for a number or different controller and charger options.
  3. The front mounted Charger also mounts on the Controller/Charger bracket above the Nose Rack. For larger chargers of controllers, the charger could be mounted in the trunk - see item E below.
  4. The High Voltage Enclosure mounts on the HVE bracket on driver side of the Top Rack. It contains the Contactor, Controller Fuse, Auxiliary Relay and Ammeter Shunt.
  5. The charger port replaces the fuel cap under the fuel door. A J-1772 connector (recommended) or other electrical connector can be used in this location.

Why a Miata?

We decided to focus our first kit on the Miata because:

  • They’re light - 2214 lbs - which means less mass for an electric motor to move around.
  • They are fairly aerodynamic - .038cd - which helps at freeway speed.
  • You can find them used in good shape inexpensively.
  • Most have manual transmissions, which is required for an electric conversion.
  • Being a convertible, in most climates they don’t need air-conditioning.
  • Most are well cared for - they were an "IT" car that some people gladly paid a premium for.
  • Parts are easily available, including body kits, low profile headlights, roll bars, etc.
  • Their styling is classic, some say iconic.
  • They are fun to drive!

back to list

What's included in the EV Miata Starter Kit?

The Starter Kit includes all the pieces that need to be fabricated to fit the Miata:

  • Nose Rack
  • Top Rack
  • Trunk Rack
  • Motor Mounts
  • Controller and Charger Bracket
  • High Voltage Enclosure Bracket
  • Detailed Instalation Guide

The motor, controller, charger, batteries, etc. are all available off the shelf from a number of suppliers. Rather than try to compete with these businesses, we decided to focus on the custom parts. This method provides two great advantages:

  • you can find the best deal on the components
  • you are free to make purchases as your budget allows

back to list

Are the battery boxes aluminum or steel?

Our battery racks, actually all our components, are made of steel. We believe the weight savings of using aluminum wouldn't be substantial given the overall weight of the vehicle. Plus, we believe that steel will protect the batteries - and people - much better in the event of an accident.

back to list

What tools are required to build the kit?

Our kit is designed to be assembled using common hand and power tools. There are two tools required that most people don't have in their shop which can be either rented or borrowed.

  • Engine Hoist - this is used to remove the engine from the car and to install the motor. It's a common tool for home mechanics and can be rented from most tool rental shops
  • Cable crimper - this is used to make your battery cables. This is a less common tool, but you may be able to rent one, or borrow one from a local EV club.

Also, our kit doesn't require removal of the gas tank for two reasons:

  • Removal of the Miata gas tank requires the rear subframe (differential, rear suspension and brakes) to be removed. This is a big job that would be best to avoid.
  • We didn't want to put batteries in the cockpit for safety reasons

With our kit the gas tank is drained but remains in place. It's not heavy enough to negatively affect the car's performance. Weight distribution is maintained by balancing the pack between front and rear.

back to list

What is the delivery time for a kit?

Each kit is made to order. Expect 3 - 6 weeks from when an order is placed for delivery.

back to list

How long will it take to build?

There are a number of factors that will determine how long a conversion will take:

  • Your mechanical abilities

  • Availability of parts

  • Availability of tools

  • Your schedule

If you have good mechanical skills, all the parts, all the tools and could devote 8 hours a day to the project, it's estimated to take 3 - 5 days to complete the project. If you have average mechanical abilities and are planning on working on the project only during weekends, plan on 4 - 6 weeks to complete the project.

back to list

How much does the entire project cost?

In round numbers, the entire conversion will roughly cost from $12,000 to $23,000, depending on the battery type, options and whether you currently own an early Miata or not.

Please see the project estimate for a breakdown of the costs involved.

back to list

Is the motor AC or DC?

Your choice - the kit works with DC or AC motors and controllers.  DC motors provide more torque, so DC based cars are generally faster. AC motors are more efficient and support regenerative braking, so AC based cars generally have a longer range per charge.

back to list

Does it have regenerative braking?

Regenerative braking is offered with AC motors and controllers. DC motors and controllers do not provide regenerative braking reliably.

back to list

Is the motor hooked right to the wheels?

No, the kit uses the standard 5 speed transmission. You'll keep it in 2nd around town and 3rd or 4th on the highway. It drives a lot like an automatic - since the motor doesn’t idle you rarely need to use the clutch.

As an option, you can choose to go clutchless. This option doesn't use a flywheel, so it reduces the weight and drag on the motor substantially. Shifting requires a little more attention than when using a clutch, but a lot of EVs are setup this way and for the most part, the owners are quite happy with it.

The Soliton1 controller has a setting that will make the motor "idle" - spin at low speed rather than stop. This spinning allows the automatic transmission to function normally. Naturally this extra spinning of the motor will impact the range as will he automatic transmissions reduced efficiency, but if a manual transmission is keeping you from going electric, this may be the answer,

back to list

How many batteries and how many volts?

The lead acid version has thirteen 12 volt deep cycle Optima AGM batteries - 4 in the nose, 4 above the motor and 5 in the trunk, all wired in series for a total of 156 Volts. These are sealed, they never need to be watered and won't leak or splash acid even if punctured.

Of course, Lithium batteries are also sealed and don't need maintenance like watering. Our kit is designed to work with a number of Lithium Iron Phosphate (LiFePO) batteries (which do not have issues with thermal runaway).

There are a lot of battery options on the market today - each with different ratings and dimensions. We provide some examples on our Estimates section, but it is in no way an exhaustive list.

back to list

How far can you go on a charge?

The Lead Acid version gets about 20 miles per charge with a DC motor and controller or about 25 with an AC motor and controller. Lithium options can go up to 90 miles on a charge. Your range of course depends on the batteries you use, your terrain and driving style.

back to list

How long does it take to charge?

Charge time depends on the rating of the charger used. The Lead Acid version with the 3KW Zivan charger takes about 6 hours to charge when the pack is fully discharged. A 6KW charger would take roughly half this time. One thing to note,  since most charging is done after midnight when the utility rates are (usually) the lowest. A 4 hour charge time may not provide any real advantage over a 6 hour charge time, unless you need to drive to work at 4:00 AM...

back to list

What’s the car's top speed?

The top end is estimated at 93 mph. Speed, however, reduces your range substantially.

back to list

How much does it weigh, and does it handle okay?

The weight of the converted car depends on the battery configuration you choose. Here’s a chart to give you an overview:





Front   Rear
Stock first generation (NA) Miata (1992) 2214 - 1151 1063 52% 48%
Converted car without battery pack 2082 -132 1092 990 52% 48%
Lead Acid AGM 2680 466 1460 1220 54% 46%
40 Amp Hour Thundersky LiFePO 2399 185 1277 1122 53% 47%
90 Amp Hour Thundersky LiFePO 2484 270 1325 1159 53% 47%

In general, the converted car handles well, as the weight distribution numbers indicate, though it will feel a little heavier than stock

back to list

How can you make a kit that fits different motors, controllers, chargers and batteries - aren't there a lot of compromises?

We found that the "one-size fits all" approach to electric Miata conversions wasn't the right one. Our kit is designed to work with a number of motors, controllers chargers and batteries because that's what our customers wanted. Of course, we can't have instructions for every possible component in our Installation Guide, so we refer to the component manual where needed.

The battery racks are another issue... We sized the racks to accommodate a variety of battery types, but some batteries will be too big to fit in any useful quantity and others may leave a lot of open space.  Some adjustments will be necessary.  Converters often use non-conductive plywood or plastic shims to keep the batteries from moving from side to side in the rack. A sheet of clear plastic is typically used to provide downward pressure on the tops of the batteries.

back to list

Do you need suspension modifications?

No, you don't have to upgrade the suspension since the battery pack isn’t much heavier than stock and the weight is well distributed. We do lower the front sway bar 2" to clear the Nose Rack.

back to list

What are the little boxes on the batteries?

Those are regulators. Since the batteries are in series they all charge together and some will "fill up" faster than others. The regulators keep the full batteries from getting overcharged while allowing the batteries that aren’t fully charged to "fill up". This applies to both Lead Acid and Lithium battery types.

back to list

How do you deal with the power brakes?

In an ICE car, the power brakes work off of the engine’s vacuum. In an electric car, we need to add a vacuum pump to create the vacuum.  The vacuum pump mounted below the battery rack on the passenger side beside the motor. It is plumbed to a vacuum switch, so when the brake booster needs more vacuum it turns on to keep the brakes working.

back to list

How do you deal with power steering?

Miatas come with both manual and power rack-and-pinion steering. Rack and Pinion is a very efficient design and, though the front of the car is heavier than stock, it's quite manageable with manual steering. Most conversions will either use the manual steering or if the car came with power steering, remove the power steering pump and loop the lines back to the steering box so that it doesn't run dry.

If you do need to go with power steering, there are a couple of options:

  • You can add a small electric motor to drive the pump or put a pulley and belt on the tailshaft of the motor.
  • The Toyota MR2 had an electric power steering pump that could be used. I understand these are available from junk yards and from auto part stores. Here's a link to a conversion where they used the MR2 pump: http://www.driveev.com/jeepev/convpgs/psteer.php
  • You can also buy a complete kit to add power steering: http://www.evsource.com/tls_steering.php

As for placement, there is room under the Nose Rack or beside the IOTA DC/DC converter. Another option is to mount the pump where the vacuum pump is located - under the Top Rack on the passenger side - and move the vacuum pump to another location.

Even with an electric pump, power steering will impact your range. We would recommend choosing a battery option that had at least 25% additional range to provide adequate power.

back to list

Can I keep the air conditioning system in my converted car?

In general, air conditioning systems take a lot of power. One of the reasons a Miata makes such a great electric conversion is because it is a convertible. Hot weather is a good opportunity to put the top down and enjoy the breeze. Another option is to leave the top up, but lower the windows and unzip the back window. This will keep the sun off the occupants but allow the air to flow through the cockpit.

If you live in an area where air conditioning is a necessity, then you may want to consider using a unit like the Cool Blue or assemble your own.

We haven’t done an installation of the Cool Blue unit with one of our EV Miata Kits, but they are compact and should be able to be adapted to work. Let us know if you are planning on including air conditioning in your build so we can make sure you have the needed room.

back to list

How do you warm the interior in cold weather?

A heater of some sort is needed to defrost the windshield and warm the interior in cold weather.  An ICE car is warmed by the waste heat created by the engine. This heat is transferred to the cooling system which is connected to a small radiator (heater core) mounted under the dash.  Since an electric car doesn’t have any waste heat, another solution needs to be devised.  You can replace the heater core with an electric unit or, add a small electric water heater and pump to route the heated water through the heater core. A more common solution is to install a hair dryer in line with the vent pipe under the dash behind the glove box. The power can be provided from the battery pack, since the dryer will work on either 120 or 220 volts. A switch mounted on the dash can turn the dryer on and off.

In any case, you will find that the car's cockpit heats up quickly under electric power.

back to list

Does cold weather affect the car’s performance?

In general, batteries don't hold their charge very well at low temperatures. We would recommend wrapping the racks in insulation if the car will be in below 40 degree weather for extended periods. A battery warmer is a good idea as well. There are a few battery warmers on the market or you can make your own.

Battery warmers could be installed below the Nose and Trunk Rack. The Top Rack doesn’t have the clearance below, so the warmer would need to be installed in the rack below the batteries. The battery hold down straps would then need to be shimmed since the batteries would now be higher than originally designed.

So how much will an EV Miata conversion cost?

The answer is - it depends... Since our EV Miata Starter Kit supports different components (controllers, chargers, motors, etc.) and different batteries, a number of factors need to be considered in determining the total project cost. Let's go through some examples to illustrate:

First we need to take a couple options into consideration...

You may or may not currently own a Miata, so a "donor" car may not need to be purchased First generation(NA) Miatas can be found on Craigslist for around $1,000 - $1,200 with second generation (NB) generally running a bit more. Of course these are high mileage cars or have known engine issues... Now if you already own a Miata, then you don't need to add this into your cost. Since quite a few of our customers already hav a Miata donor, we are going to leave it out of the calculations. Just remember to add it in if you need to purchase a donor car.

The next option is whether you want to do your own welding, plan to bolt together your own conversion or have a shop perform the EV Miata conversion for you?

  • The EV Miata Fabrication Diagrams with Installation Guide are offered at $495.
  • The EV Miata Starter Kit with the Installation Guide is priced at $2,500.
  • Turnkey car conversions start at $7,500 plus components - which we'll look at next...

Now let's look at four example conversions:

#1 our test car

We built our test car in 2008 when Lithium was still relatively unproven and quite expensive. This car was intended as a short distance commuter car with healthy amount of performance thrown in. If you have a short commute or can charge at work, this configuration may fit your needs.

Component Type Cost
Adapter: 9" motor to Miata 5-speed $879
Controller: Zilla LV 1K $1,950
Motor: WarP 9 brushed DC $1,700
Charger: Zivan NG-3 $1,075
DC/DC Converter: Iota DLS-45 $131
Battery pack: 13 Optima D34M Lead-Acid AGM $2,210
Rudman Mk4
(we used HotJuice Electric equalizers, but they are no longer being manufactured)
Miscellaneous: Cables, lugs, wire, relays, etc. $2,000
Total Components: $10,554

Estimated Range: 20 miles/charge

Estimated Price with EV Miata Fabrication Diagrams: $11,049

Estimated Price with EV Miata Starter Kit: $13,054

Estimated Price with EV Miata turnkey conversion: $18,054

#2 inexpensive example

A number of you have asked for a less expensive option that may sacrifice some performance. This example uses a Curtis controller, an 8 inch motor and other less expensive components. Note that the Curtis 1231C controller maxes out at 144v nominal, so only 12 batteries are used in this option.

Component Type Cost
Adapter: 8" motor to Miata 5-speed $879
Controller: Curtis 1231C $1,689
Motor: ADC 8 brushed DC $1,807
Charger: Elcon HF/PFC 1.5kW $560
DC/DC Converter: Iota DLS-45 $131
Battery pack: 12 Optima D34M Lead-Acid AGM $2,040
None $0
Miscellaneous: Cables, lugs, wire, relays, etc. $2,000
Total Components: $9,106

Estimated Range: 18 miles/charge

Estimated Price with EV Miata Fabrication Diagrams: $9,601

Estimated Price with EV Miata Starter Kit: $11,606

Estimated Price with EV Miata turnkey conversion: $16,606

#3 long range example

This uses an AC motor and controller coupled with a large Lithium battery pack. Now there are a number of LiFePO manufacturers and amp hour rating of LiFePO cells on the market today. We are using CALB since they currently seem to be a popular choice. you need to take 2 things into consideration when sizing your pack for LiFePO batteries: the dimensions of the battery and max voltage of your components (typically the lowest maximum nominal voltage supported by your controller/motor combination). In the case of the HPGC AC-50, the maximum nominal voltage is 108v, so that is the nominal voltage we will be using in this example.

Component Type Cost
Adapter: 9" motor to Miata 5-speed $879
Controller: Curtis 1238 $2,310
Motor: HPGC AC-50 $2,310
Charger: Elcon HF/PFC 3kW $1,100
DC/DC Converter: Iota DLS-45 $131
Battery pack: 34 CALB 200 amp/hour LiFePO $9,622
MiniBMS $452
Miscellaneous: Cables, lugs, wire, relays, etc. $2,000
Total Components: $18,804

Estimated Range: 98 miles/charge

Estimated Price with EV Miata Fabrication Diagrams: $19,299

Estimated Price with EV Miata Starter Kit: $21,304

Estimated Price with EV Miata turnkey conversion: $26,304

#4 mid-range, higher performance example

In this estimate we'll use a Soliton 1 controller, a 9" WarP motor, PFC-30 charger and ThunderSky/Winston batteries. Since the controller is quite large, we'll be mounting the charger in the trunk. The Soliton is an interesting controller in that it incorporates the Contactor and relay functionality, simplifying the wiring and reducing (maybe eliminating, in some cases) the need for the High Voltage Enclosure.

Component Type Cost
Adapter: 9" motor to Miata 5-speed $879
Controller: Soliton1 $2,999
Motor: WarP 9 $1,700
Charger: Manzanita Micro PFC-30 $2,849
DC/DC Converter: Iota DLS-45 $131
Battery pack: 57 Thundersky 100 amp/hour $8,550
MiniBMS $733
Miscellaneous: Cables, lugs, wire, relays, etc. $1,875
Total Components: $19,716

Estimated Range: 68 miles/charge

Estimated Price with EV Miata Fabrication Diagrams: $20,211

Estimated Price with EV Miata Starter Kit: $22,216

Estimated Price with EV Miata turnkey conversion: $27,216

Now of course we can't list all the possible combinations or account for various components changing spec or going out of production. Tax and shipping will be extra and depend on your location. These estimates are only intended for planning purposes, but were as accurate as possible at the time of publishing, which was October 12th, 2012

about us

EV Miata is the first product offering from EV Works. EV Works is a a small, self-funded startup in the San Francisco Bay Area. We are a team of concerned individuals who wanted to do what we could to address some of the most pressing problems in the world today - climate change, air pollution, domestic security, trade deficits and the bias toward disposability in our culture. Quickly we recognized that electric vehicles were part of a solution. They reduce pollution and green house gas emissions, even when drawing power from coal fired power plants. They consume no oil or gas, which reduces our need for imported oil and the domestic security issues oil is believed to fuel. But electric vehicles have limited range, reducing their practicality to a small group of drivers - or does it?

Electric vehicles fit most of the drives we make today, even with current range limitations. The belief that we all need to be able to drive 250 or more miles without refueling/ recharging is based on the model that we need to go somewhere to do this refueling/recharging. With the ability to charge at home, electric cars do not need to offer extended range to meet the needs of most drivers. With the average US commute of 29 miles (according to the Bureau of Transportation Statistics), an electric vehicle with the current range limitations would meet the needs of the average commuter today. Furthermore, government studies show that 51% of commuters drive 10 miles or less to work. While a current electric vehicle may not meet all the driving requirements of a household, it can make a great second car to handle commuting, going to school and back, getting groceries and running errands.

Though many manufacturers claim to have electric cars in their future plans, there are few freeway legal electric cars for sale today. So how does one get the advantages of an electric vehicle today? The answer for many is to build their own. There are thousands of electric vehicles on the road today that were once gasoline powered. These "conversions" are generally one-offs done by amateur mechanics/electrical engineers who wanted to convert their car to electric. Converting a car from gas to electric drive "upcycles" rather than recycles the vehicle. With recycling, the vehicle is returned to it's "elements" if you will - steel and potentially plastics that can be reused in the production of another vehicle of product. With upcycling, the vehicle is not recycled, renewed or restored, but altered into something better than it was - an emission free vehicle. Converting gas vehicles to electric addresses our concern of disposability - the gas car is not sent to a disposed yard when its engine is at the end of its life, but converted to electric.

The first EV Works electric conversion kit is for the first generation (NA) Mazda Miata with plans for the second generation (NB) to follow. The Miata was chosen for it's lightweight yet rigid construction, good aerodynamics, desirability and availability. The kit is available in a basic package, that allows the builder to independently purchase the hardware components. Two battery types will be supported - less expensive lead acid (AGM) and higher range Lithium Iron Phosphate (LiFePo). The battery racks in the kit are designed to handle either battery type to simplify installation and allow simple battery upgrades if the owner so desires.

A detailed budget was created, a donor Miata was purchased and the conversion process began. A web site and blog were created to evangelize and inform the public as well to test interest in our plans. The feedback we received was very positive, with many visitors asking for details on components and kit information. We then posted a survey to see what components and type of kit there was interest in. We had over 500 responses with the majority requesting the components we are offering today.

The EV Miata Kit is the result of extensive research, design, fabrication and real-world road testing. We are proud of our EV Miata and know you will be proud of the electric roadster you will create with it.
