Production EV battery packs almost always include some sort of BMS and have lots of interlocks and safeties. You don't really have to do much to work with them other than to talk to the BMS and not exceed voltage and current limits. If you do, the BMS will trip the pack's internal HV contactor. Safely installing/modding/repairing automotive fuel systems is likely just as, if not more, dangerous if you don't know what…

Do any of those BMS do cooling? The parking lot at work hits 115F regularly and that is bad for batteries. I'd love a conversion, but I worry I'd get nissan leaf battery life vs tesla s battery life. I'm thinking something like an old mazda bongo import. For that matter, do any of the kits power the ac compressor?

This writing is brilliant edit: just got to the author’s blurb at the bottom. He was an engineer on the original Miata, so it’s no surprise that he knows what he’s talking about.

The irony being that the Miata is none of this. Notably reliable and easy to drive.

I think part of the fun of 914's is how raw they are. Once you get all the individual car's eccentricities down its the same fun, but you feel like its all your secret on the good days when the car is working as intended.

The fact that they are dog slow is made up by the fact that your sitting on this little motor making a huge racket. Its the "I must be going fast, given how much noise i'm hearing" thing.

as a guess it would go something like this: step 1. prepare a usb with files needed to jailbreak the car and be able to connect to your wifi step 2. setup a home network with dns/ntp and a reverse engineered tesla server that will authorize the car to work step 3 set date to reasonable values that the car will accept step 4 do some button dances to start the car from the usb … ill leave the rest to your imagination

You will also need a Raspberry Pi 19 and a GSM transmit module to impersonate the old-timey cell towers they used to use. You can purchase one for about $3 or so and run this script...

After you have hand built a new battery that fits it, built a LCD shim to connect to whatever the latest standard is, etc.

Older cars are simpler, both in total, as in the requirements to retrofit replacement parts. Your average machine shop/etc will be able to keep that 914 running for the next hundred years. And when they stop selling gas, you can convert it to run on everclear.

This reminds me of back when I was at Bell Labs back in the 1980's and there was a "user manual" of how to crash the Unix OS on the PDP11's in our lab. The idea being if you just tell people how to do it they won't try to show how clever they were by doing it. Also, it was a warning what not to do, but it also discouraged anyone from thinking they found a new flaw or whatever.

> The dual Webers don’t have chokes and you’ll be squirting fuel down the barrels with the accelerator pumps for the necessary priming regime. The engineering Puritan will want to know that the Webers are a retrofit, a hack for escape from the factory's refractory -- but cutting edge tech in the 70s! -- VW electronic fuel injection. The EFI "brain" was a box the size of a small modern laptop, stuffed with individual…

I had to diagnose an issue with said brain on a car from 1982. Previous owners could not figure out the issue. The car's engine would rev "bounce" at idle like it had a big cam, but it didn't go away when driving, making driving not very fun. So I got the Scirocco for dirt cheap. I realized on day that if you opened and closed the hood a couple times, the issue would fix it self, and it was very repeatable. I realize…

I love the K-Jetronic mechanical injection system in my '83 SAAB -- only because I've never had to mess with it very much. Plus, unlike a lot of the more obscure things on that car, the K-Jet system was also used on VWs, Porsches, and Mercedes, so there's a lot of info out there.

A lot of this article rings true for cars I've had (and some I still have) but I tend toward cars that are simpler mechanically and tend to fail more fundamentally: the keys all lock fine but the suspension mounts all rust out. This year has been an exercise in chasing leaks (gas, brake fluid, coolant, and now ATF) between my two daily classics. All I need is power steering fluid and I can complete the whole set!

Is the electric conversion still a thing? I want an eclectic car with no monitors, no software updates, no surveillance (none of the new electric car offers that - they are calling home for updates and god knows why way too often, and they have bigger monitors than my 14" work laptop).

> they have bigger monitors than my 14" work laptop Unfortunately, though you might find one with a smaller screen, you won't find ANY new car with no screen these days -- backup cameras (and, by implication, a screen to see its feed) have been required on new cars in the US since 2018.

Some cars house the screen inside rear view mirror (notably some Subarus), as there is no specific requirement on screen size.

>>none of the new electric car offers that Eh? I literally got a brand new electric VW e-Up last week, it's exactly that. It even still has analog dials, and VW provides a mount for your phone instead of an "infotainment" system. The height of sophistication is DAB radio and heated front window and seats. I highly recommend it, it's a hoot - and with 150 miles range and rapid charging capability it's more than enough…

The problem isn't only the dashboard, it is the pervasive surveillance. This car is better than most but I've read here before that it still had some flaws. Can't find the post at the moment however.
