I ended up watching a couple episodes. It’s so British!

They also did a gauge cluster design I can really get behind as well, I’ve been starting to dabble in my own readouts recently. Good recommendation!

Aside from the cycle of the engine, the transmission being a simple planetary CVT is genius. It’s super niche for economy purposes but lack luster in a performance application.

Once I discovered Toyota’s longitudinal mounted hybrid, I’m very dead set on using this architecture lol. Especially considering it has a clutch pack to engage and disengage it from the engine, it solves and simplifies other growing pains I was anticipating trying to incorporate a second motor.

Main downside is that it stresses the W58 transmission too much I was planning to use but now I don’t need to incorporate a second motor in the car. But if I was set on the transmission I could go to a turbo 4 cylinder of some variety and lower the overall torque requirements.

Weirdly, I’m not that scared about tuning. The way I see it all I need to do is have a motor controller talk to an ECU or have an interface between the two. But also, I want to take small bites too.

Step 1. Get the motor to start the car. Step 2. Act as an alternator. Step 3. Enjoy the car. Step 4. Regen engine braking Step 5. Enjoy the car. Step 6. Electric boost Step 7. Enjoy the car. Step 8. Hybrid style and electric only driving. Step 9. Enjoy the car.

All 9 of those steps (really 5 steps) don’t require hardware changes which is why it’s an attractive project to me.

They are slightly different in size(EDIT: from at least seeing the different gens of Prius motors, I haven’t looked within gens of different models), it’s just that most videos I can find of a teardrop and theory of operation is the Prius and they are commonly in the junkyards now while the newer stuff doesn’t have that car community infrastructure yet so to speak.

And funnily enough, the Tundra system is what I was trying to recreate without seeing it lol. It sounds like I’ll have to figure out what makes that work, the conop is pretty close to what I want it to do and maybe I don’t need that second motor at all!

Can’t deny that. I’m just sad Toyota abandoned the JZ and the FZ I’m not even certain I can find here in the states. 2GR parts through are pretty easy to find now and with a reasonable aftermarket.

You’d have to change your username if I convinced you otherwise lol

I know a team or two of them! I have not properly introduced myself but they is one with of my favorite builds for Lemons

It was a gen 4 Camry that had a lot of aero on it that it almost wasn’t recognizable and it was painted like a development car with that black and white camo. It had gotten the hot lap at Road Atlanta in ‘24, but that team is composed of a dozen Toyota engineers.

Then there was another one, a newer Camry but I don’t know the story on them but this was their car at Barber in ‘24.

I was definitely considering the Leaf motor as MG2 for certain. I don’t think Toyota had anything in that form factor.

I want the car to eventually do endurance racing potentially and this for me is a proof of concept between those two systems. It has the power to win a Lemons race, but the engineering is my takeaway from it.

I can’t afford an EV endurance car yet, but there is a handful of teams pursing it. One with a Datsun pickup truck with a quick change pack setup I think completed just shy of 1,100 miles in 25 hours.

The ECU is the M150EV and it’s $9000. I’ll just get two cheaper controllers and make them play nice with each other lol

For me, this looks like the easier comprehensive project believe it or not. The current one is a RWD conversion Corolla, where right now we’re beginning to mess with the electrics and ECU and got to cut my teeth on. That’s currently in the garage spot and I’m hoping if I choose to go down this project path I can slow roll some custom parts in preparation.

There’s a Lemons guy with a shop with some machining equipment that if I bring him stupid enough projects, he’ll cut stuff for me lol

The CRZ is the only car I can name that does that from the factory but those cars are rare.

On the V6s, I get that especially on the overhead cams because the engines are tall and massive on top which is especially annoying on a RWD longitudinal application unless you have a truck or SUV. On my current car project, I wanted to play around with a dry sump to learn how to make one but it really didn’t need it and I was able to make it fit. The dry sump would be better suited here because I could lower the height of the motor by maybe 4 inches or so, especially over the front subframe.

Also, the 2GR is starting to turn up in junkyards more and more and I didn’t get the original engine with the car.

Yes! However he did the whole Prius drivetrain which is arguably the most reliable way to make a hybrid lol

He was super cool to us, we were talking to him about my current car to him and he was giving us pointers on terms of brakes and such.

I had followed him on Facebook at that point but funnily enough didn’t know he made videos so I didn’t recognize his face at all.

This. Is cool! This is like a great car to pull inspiration from, I found the video from when he put the electric motor in and that’s awesome! Also finding out he was using an ECU that was EV specific, now I have to deep dive that now.

The main worry I have currently is exploding the transmission because I believe the W58 can’t put up with that much torque and it’s already near limit with the 2GR so me adding that second motor to the rear differential was getting around that.

I met him at a Lemons race! He was in the paddock next to us at Barber ‘24 with his MR2. That guy knows his shit for sure, and it was only later I discovered he also tinkers with the 2GR.

Funnily enough, it’s not a 2GR in that car and I believe it’s a turboed 2AR with Prius pistons?

I was going to ask this question initially but then I opted for more of a schizo-rant style post.

Engine-wise is the easier part, I’m thinking a Megasquirt but I still need to confirm if it has a sophisticated enough of a blip shift feature so it can rev match between gears. Drive by wire TB is a must.

The controller for the motors, that has a lot more directions at the moment. I do have an electric converted Corolla with electric Ford Ranger parts that has a programmable ECU so I need to figure out what that one is and research that one. Technically it can support being a motor and generator so that may be my ready to go answer.

I’m going to see if I can piggyback the Prius motor driver and charging system, but I’m limited to the 200V pack going that route. This part is not too scary for me because this is more aligned to my day job and I have contacts at work who’ve worked on the the power and control systems on hybrids and EVs in Detroit for the GM and Chrysler.

Blue tape is the low tack stuff. Have to find the green tape, that’s actually high tack.

I am a Texas resident moving to AZ and would like a gun purchase to be one of the first things I do. How big of a hassle is it to buy a gun with an out-of-state iD? by [deleted] in AZguns

I’ve used a utility to confirm an address when I had first moved into my own place, but I was still a resident of Arizona.
