I was going to suggest a 97-03 Cobra Mustanf iRS because they USE to be relatively cheap, amd would take little effort to fit under a Corvette, but wow did they jump in price!! 3 K plus now when you use to be able to get them for around 1K...Got mine for 1400 rebuilt.
I believe the same era Ford Thunderbird used the same IRS..
Nope, the only thing they have in common is the internals of the 8.8 centersection. The T-BIRD IRS is nice but it is much bigger and heavier than the Cobra.
Cobra
T-Bird
A really cool thing, and it actually won design awards for it, is that it bolts into the solid axle version of the Mustangs control arm mounting points. Genious.
this opens up CAN protocol development for the gauges and sound generator, which i'll likely do first since that's low cost but gets me a lot of experience with CAN and embedded systems
the sound generator may be a whole *** job though, i'm getting tons of conflicting recommendations of what kind of system to use to generate sounds, from using a digital audio workstation (DAW) on a raspberry pi , to programming languages designed to generate sound by code alone , to complex "event scripting" languages designed to orchestrate big audio visual experiences
The day will come when conditions/technology are right, owners will commonly 'resto-mod' cars from high-priced and dirty gasoline (the future mindset) to electric. Some outfit will probably even make fiberglass 'look-alike' housings which mimic the look of a Chevy 350 engine and can be slipped over the top of an electric motor to give that 'original look'.
Might not be that far off, who knows???

turns out you were ahead of the curve my guy, this guy is doing exactly that and i'm.....not a fan honestly https://www.webbmotorworks.com/
well this slightly sucks i'm attempting to do more rough battery placement and the results are....not ideal
with chevy volt modules, two packs, barely 34kwh worth, i have to pack the engine + transmission area and gas tank area and im still one block short
on the flipside i re-did the lg chem battery placement to allow for way easier chill plate design (four larger plates instead of a ton of small ones, and the positioning seems to be excellent, fits comfortable with some room to spare
but again, these lg chem bricks are getting really scarce, i could easily be supply limited more than cash limited also, participating in this thread, wiring these things might be much more of a pain than expected
so im hurtling towards either a battery solution that may not even fit, or one that i can't even get the batteries for
great, i think
on a more optimistic track, i'm looking into photogrammetry very seriously after finding the results of this particular guy on reddit who did exactly what im doing, scanning the engine bay to size a battery box, and his results were pretty spectacular I 3D scanned my engine bay : E30 (reddit.com) 4CcesXg.jpg (1114×1082) (imgur.com) z7r5Bb4.jpg (1407×1876) (imgur.com) i'm looking into throwing together a really good photogrammetry gear set for like $1500 of used body, lense, and ring flash, and hopefully i can get a "good enough" scan of everything i need, including the components themselves
There is plenty of space where the storage compartments are behind the seats.
My question is, Do you need to configure the motor in the engine compartment or could you place the motor behind the seats and use the engine compartment and gas tank area for battery placement?
I can’t remember if you already looked at this as an option or not.

i really dont want to compromise the only (small) storage the car has. At most, i'd put the AC/DC converter and charge controller back there or something...but i'd have to drill holes through the interior for the high voltage cables to come through which is not ideal
i'm using a tesla model S large rear drive unit, which essentially replaces the differential with a 600hp motor, so i'm effectively already doing what you suggest, and using the engine bay + gas tank for batteries]
i can probably pack more batteries up front but i need an accurate engine bay scan to check tolerances, and i unfortunately may lose that cool "battery box that looks like a v8" look i was going for
I think this project is really cool.
I would pack the engine bay with your batteries and ditch the idea of the foe V8 look.
Either way the engine bay would look slick.
realization from the diyev sister thread, thinking about using 12 lg chem bricks instead of 18 to save on cost, packaging complexity, and mass
some back of the napkin math on weight gain looks extremely promising 456lbs of batteries, 80lbs of cooling, 290lbs of motor (not including coolant, battery box mass, cabling or secondary bits like chargers and converters) = 826lbs when converted 575 small block chevy engine DRY, 100lbs for my TKO500 manual transmission, 100lbs of exhaust including mufflers, 156lbs for the 28lbs gas tank with a full tank of gas (not including coolant/oil mass plus fuel lines) = 931lbs stock
so they're already extremely close, within 100lbs, and i save even more weight vs a big block engine (which weighs more like 685lbs) this 12 battery configuration is looking nicer by the second...especially if DC fast charging or my charge generator trailer idea pans out.... but even at 18 bricks, i only gain another 184-and-a-bit lbs of mass for another 16kwh of capacity which is huge, translates to another 36 miles of range at the nominal 80% capacity and 350 watt hours per mile energy consumption
Regen is a property of the motor and the motor controller
the tesla large drive unit does great regen, and the VCU200 motor controller is more than happy to use regen when you brake
i may need to play some games with the brake pedal though, engineering in a bit of a deadzone or initial pedal thing where if you push it a little, it engages only regen, but push it more and the mechanical brakes are engaged

Yes, I should have been more clear. Was actually asking if your controller supports regen. Glad to hear it does.
yeah the vcu200 has an almost disgustingly large feature set, I probably wont even use half of them, this is on top of it having really powerful CAN communication stuff, meaning i can add extra things on the car which can "talk" to the vcu very easily

I communicate with AEMnet (CANBUS) with my arduino transmission controller. Let me know if you want the code for that.
I am reminded of a vid I saw where a 66/67 chevelle BB car was converted to tesla rear drive.
Basically the guy put the bats in the area where the bb had been and claimed the same weight was achieved.
I think the builder was in Sweden?
BB went in C3's so the same could be done.
Sorry I can't remember more or names to help find the vid but he had a way to put the tesla motor in and built some kind of cradle setup.
Maybe someone say the vid and can point you in the right direction.
The guy did a real good job and overcame a lot.
Smart dude.
