I understand your sentiment, but you aren't well informed enough on an electric conversion. my plans would be to have a lighter, and better performing car when I'm done.

I'm not taking anything away from the enthusiast community, I've found the car I'm looking for and hope to pick it up after the holiday. I'll let you guys know and look forward to getting more info about specific parts I'll need down the road.

hydrogen drive is terribly inefficient and usually ends up weighing more based on the extra safety features needed to drive around with hydrogen.

Hi Duct tape
Did you get an e9? I'm looking forward to seeing your project.My Uncle install a FWD diesel engine and transmission from a Toyota car into a spray rig using 1 drive axle to drive the front axle and the other drive axle to drive the rear axle making it a 4WD spray rig so thinking out side is what makes America so great! With that said how did you get the call name Duct-Tape? Good Luck and please post pictures, Tim.
 
thanks!

I got the nickname in my racer days, we were doing some trackside modifications to my car and I had a few seconds to get back in before being disqualified.
I whacked my head getting out from under the car. I finished the race by taping a gash closed with duct-tape.

The Tesla is ultra quick (0 to 60 mph in 3.9 seconds) but it’s a very light car. Believe me I know, I had one stored in my mom’s garage for several weeks so I had plenty of time to look it over. My friend worked in production on the “Royal Pains” TV show and actually drove one, he said it accelerated like a roller coaster going down the first hill. ~ John Buchtenkirch
 
I have no intention of running in the tesla crowd, if I wanted to spend 60-80k on my conversion, I guarantee that I could beat one into the dirt.

I'm building a touring coupe for a reason, having a car that rides higher means lift. less drag, more efficiency. I will be re-skinning the underside of the car to make it more slippery.
My plans are more reasonable, 0-60 in about 5-6 sec. top speed of 90 and a range of about 75 miles. any more than that and I will be putting too much strain on the BMW parts I plan on keeping. longer range or higher speed would preclude making more drastic changes to the car, massive suspension upgrades, custom transmission, changing the interior to make more room for batteries- etc.
I still want to retain the "cool factor" otherwise I would just use a kitcar shell and just make a battery box on wheels.
I hope you have a better idea of my plan now.
 
So you are saying that you can outperform a tesla with a budget of only
60 -80k, a car whose R&D had cost several million dollar? I think you should work for tesla then.
As you could save the company large sums of money and still have huge advancements compared to their previous product,
or maybe you'll be having a rude awakening as far as finances and funding is concerned.

As far as your project is concerned, I can't wait to see the result.
Good Luck

YES, I am.
Are you saying that if you had 60-80k, you couldn't build a car that would outperform a new M6?

I hope you mean it, I'm excited and will accomplish what I set out to do. (although it may take a few months with my busy sechedule)

I think you are comparing apples and pears here. It's by far harder to outperform one of the fastest electric vehicles
than it is to outperform an M6.

And with 60-80k to spend , i would buy a new M6.
 
sadly, its not even close to the fastest or best performing EV, I know of an electric 1987 nissan in LA that will do 0-60 in 3.2 and hit 1.8 on the skidpad. Thats just one, I can name about 8 more homebuilt.
I understand the common ideas of what can and can't be done with electrics but really, there's far more to it than the ONE sports car that is commercially available as an EV. or the general idea that they are fat, slow, and have no range. most people have the idea that lead acid batteries are the only way it's done. here's a table of different battery options to give you an idea

lol to apples and pears. I like pears.
The fact that you'd rather buy a new M6 than build something is telling. :wink:
It's okay, I still respect you as an enthusiast

Now waidaminnit. 1.8 Gs? In a Nissan? Unless large and complex aerodynamic devices and speeds high enough to bring them into play are involved, that number is silly. A Lotus Elise can squeak out a little over 1G and even an Ariel Atom tops out at maybe 1.3.

Also (and I'm trying to be helpful) an E9 is possibly the worst BMW platform into which you might drop between 500 and 2000 pounds of batteries. The absence of a B-pillar makes the E9 notoriously weak at the center of the car, and E9 rockers are typically the most rust-corrupted spots in the car. So much so, that folks who track or autocross stock E9s roll down the windows to prevent chassis flex from shattering the glass. I can't imagine you'd be translating all that weight into polar moment by placing the batteries in the trunk, but the center of an E9 is terrible spot for a whole bunch of dead load.

Have you considered an E3? It has a B-pillar and a much stiffer body cage. Less expensive or rust prone as well. Better yet, E30s have their gas tanks under the rear seats - a perfect place for a battery pack near the center of the car.
