Follow the epic saga of the car's conversion in words and photos, at the EcoModder forum. I've been posting about the project in excessive detail from the day the proverbial light went on, right up to the present.
The project thread is really long (80+ pages at last count), so set aside several evenings, at least, if you want to read it all. For those on a mission to find specific info, I made an index which links directly to the more significant entries along the way.
Also note that if you want to comment or ask questions about the car, this EcoModder thread is the place to do it - I check there regularly.
ForkenSwift Conversion Thread Index/Summary
01-16-2006 - Some general research on the feasibility/specs of a low speed, budget EV has us thinking we're going to give this a shot!
01-19-2006 - A rough cost estimate: $2631 Canadian
01-19-2006 - A list of lightweight host cars that may be suitable for EV runabout duty
01-20-2006 - Found a couple more potential host cars...
02-05-2006 - Tips for locating cheap beater cars, potential EV hosts; located a red Suzuki Swift with a decent looking body, asking price $100
02-13-2006 - More host vehicle shopping; Finally talked to someone at the forklift place who says they have a used/dead one available
02-18-2006 - Someone offered us a free Firefly 5-door, but it's too far away to go fetch.
02-20-2006 - Went to look at the used forklift tonight
02-24-2006 - Green light! Ivan and I crunched the numbers and decided to forge ahead with the project; made calls agreeing to buy the $500 forklift and the $75 Suzuki Swift
03-04-2006 - Picked up the Swift today. A closer look at the rust has me thinking it may not be salvageable, but its parts can still contribute...
03-07-2006 - Pics of the front suspension rust/welding repair on the Swift
03-15-2006 - Forklift delivered! I guess we're committed now.
03-17-2006 - Down periscope! The forklift is sinking into the driveway.
03-18-2006 - Test lift, using the 20 ton railway jack; started removing misc knick-knacks
03-21-2006 - Major forklift dissection begins! Moved it, under battery power, into the garage, jacked it up and removed the first hydraulic pump motor.
03-22-2006 - With pics: got the second hydraulic motor out and both hydraulic pumps. Starting to worry that the drive motor will be REALLY heavy...
03-23-2006 - Forklift traction motor-ectomy complete. 240 lbs!
03-24-2006 - It's gone! The forklift, that is. Called around to scrap dealers and picked one who offered to come collect the bones with their flatbed truck. Plus pics of the bittersweet occasion.
03-25-2006 - Picture (and inventory list) of ALL the good loot we scavenged from the Baker forklift
03-29-2006 - Uh oh. Up on jack stands, the underneath of the Swift is MUCH rustier than we realized. Moral: don't buy a car sitting in long grass!
04-06-2006 - Pics: we've deemed the red Swift's underbits too rusty to repair. And we've already located a potential replacement - a blue Metro of similar vintage (and in better condition) sitting in someone's yard a few blocks away.
04-06-2006 - Fixed the divots in the driveway where the forklift sank in; ALSO - picked up the blue Metro ($175 !) and made a list of its obvious problems
04-12-2006 - Began swapping good parts from the red car over to the blue car: ball joints, ignition switch, hatchback, tires, etc...
04-30-2006 - More rust! Lifted the blue car's carpet, got out the grinder, and transformed the 2 small holes into a small future brazing/welding project
05-12-2006 - Pics: the rusty floor is finally fixed
05-17-2006 - Pics: rust repair before/after; also... SPIDERS!
05-19-2006 - For a net investment of $89.85 all in, the blue car passes inspection
05-22-2006 - For a laugh, see the pic at the bottom of this post: " why bother electrifying the car when it's already a hybrid?"
05-23-2006 - Preparing to yank the drivetrain from the Swift to get its transaxle mounts, axles & shift linkage for the blue car. Those 4-cyl parts offset the transaxle further to the left, meaning more room to mount a big motor in the available space.
05-26-2006 - Ack! Discovered that the diameter of the forklift drive motor is too large! Centered on the transaxle, it will interfere with the passenger side drive shaft. Considering options to make it work... Also: pulled the drivetrain from the red car.
05-29-2006 - Motor decision: Based on feedback from the EVDL, we've decided NOT to try to use the 12 inch motor, and will instead adapt one of the two hydraulic pump motors
05-31-2006 - We're swapping the front strut/spring/hub/brake assembly from the red car into the blue one. Why? Possibly stiffer springs, and also bigger brake rotor/caliper
06-05-2006 - Pics: the red '93 Suzuki Swift (from whence the EV's nickname came) was officially put out to pasture, via hillbilly tow-bar.
06-06-2006 - Well, the blue car is now officially mine. I registered & paid tax on it this afternoon
07-21-2006 - Adapter plate cut! Still need to drill the mounting holes
08-17-2006 - Officially at the most critical engineering phase of the project: planning an approach for the motor/tranny coupler
10-05-2006 - Dropped off the motor, transmission & adapter plate (blank) to the machinist so he can finish the coupler & align everything perfectly
11-04-2006 - Back from the machinist: pics of the stuff he made for us 11-05-2006 - The blue ForkenSwift will never move again powered by gasoline - started removing its various life support connections
11-08-2006 - Internal combustion engine is out! (Plus: debate on "out the top" vs. "out the bottom" removal technique)
11-12-2006 - Pics showing the "3-cyl" vs. "4-cyl" positions of the transaxle (with motor mockup stuck on it)
11-13-2006 - Got the transmission hooked up in its "new" location, using the mount, shifter & stabilizer rod from the 4-cylinder car. This gives us more room in the engine bay on the motor side of things.
11-19-2006 - Disassembled & cleaned/de-greased the motor (hydraulic pump motors get greasy, apparently); reassembled & mounted on adapter plate, transmission
11-21-2006 - Started work on motor bracket; also, eBay purchase arrived: 225A 48V Curtis controller
11-26-2006 - Motor is installed in the car (properly... with brackets)! With pics
11-27-2006 - Whoops! The motor is spinning the wrong direction for the transmission input shaft; reversing polarity doesn't fix it. Investigating...

04-28-2007 - Project NET cost update: $978.35 CDN or about $876 US; still some good forklift & Suzukiclone parts left to sell, so this will decline.
05-03-2007 - Score! (With pic.) Returned home with a pickup truck load of used 6v batteries! Thanks Fred; thanks Allan!
05-06-2007 - There's no way we're going to be finished the electro/mechanical stuff before the Ottawa EV Expo at the end of May, so we decided to switch the focus onto making it pretty instead (body/paintwork).
05-11-2007 - If you're going to try hypermiling your converted EV (with brushed motor), you might want to keep the clutch.
05-23-2007 - OK, not a milestone, but I like them: got the "ironic racing stripes" painted on, and I like them! Also started fabricating a custom tow bar to get the car to the EV Expo in Ottawa.
