I am waiting for the tesla sedan to hit the market -- they are building a dealer here in chicago so I am very excited -- enough that I am very tempte dto put down $5k as a refundable reservation for one of the sedans!
I am aiming for for the electric motor and an adapter plate to a cvt type trans -- if I need to cut weight I am think CF hood and deck lid
I figure I have crammed a 911 6 , a SBC and a subie engine into a teener why not an electric motor
I made a cabin in upper MN for my mom basically off grid entirely -- it was an interesting project haha
What's a "SBC" engine?
I'd hold off a bit on the Tesla Sedan though, until they have a "real" working & production ready prototype, as the one which they rolled out was less than 50% & just barely moved when driven. I saw it - more of a mock-up than a true prototype. They've also had to recall ALL of the roadsters due to a suspension assembly error by Lotus.
But now that Tesla Roadster is a 200 mi range screamer in the 914's class!
Sounds like we've both looked at the same EV conversion kits online!?
...yes & that $8k Raby engine screams too!
Given that battery packs/converter-regulators are bound to get better as full production EVs come on line, I'd say that for now it's better to opt for the lower end ones (sacrificing a bit of range per charge). Then you can replace that 1st one when it wears out, & for about the same price in the future (assuming that they typically should come down with increased production & competition). Hopefully they'll be down by the time I'm ready!?
As for weight saving - I'll be needing the F&R Chrome Bumpers & Valences, F&R Deck Lids, etc. for my 73 2L resto - so I'd replace those on the stripped donor 914 with fiberglass + the rockers & anything else where I could save weight. Jettison everything else gas engine related, such as the gas tank/fuel pump/lines/etc., battery/tray/support, as well as the heavy springs, torsion bars, hinges/brackets from the OE steel F&R Deck Lids.
I'd probably also stick with the OE tall/skinny 155SR15 or 165HR15 tires on the lightest wheels possible, to reduce rolling resistance & inertia, as well as weight (maybe a mini-spare from another vehicle too). Unless there are low profile tires on 16"+ wheels which are as light & easy rolling & low inertia as those, which will work on the 914?
The stock OE seats/shells were relatively light weight - as is the fiberglass targa top, & there's a guy at 914world vendors who makes FG door & back-wall panels + upholstery sets at a reasonable cost - depending on what you get.
I've heard that the stock 914 transaxle was a good choice for EVs, but CVT or automatic electric multi-speed could be a good option, if it works with all the rest of the suspension - of comes with something equally good.
One issue/question - esp. for your back there - is cabin heat. Electric reduces range, gas/NG/propane all go back to the fuel problem. AC is more of a problem for us out here, but my 73 never had it - although I wished it had when I was in suits/ties!
My 73 2L is still all stock incl. EFI, which I'll have my long time factory 914 trained expert mechanic Hans update with all new or rebuilt electricals now, so it won't be a problem later. I'd basically done a full resto back in 80-83 before she was smashed, & Hans has rebuilt both the motor & transaxle in that process - so they only have 25-27k on them mechanically. Once that's all restored, then I can look at the EVroller.
