Make the mid-engine car on the left more like the mid-engine car on the right
Hear me out.
Parts are entirely discontinued. !!!error: Indecipherable SUB-paragraph formatting!!! . I’m interested in doing something “a bit different.” The car drives fine, but the welded subframe bolt bugs me. If I’m going to find a repair for this, I’d like to go big.
Since it’d be costly and difficult to source any kind of OEM replacement subframe, the logical choice is to do something costly, creative, and difficult.
I’d aim for a custom-fabricated subframe with provisions for two electric motors. One for each front wheel. Like an NSX.
I never use the Frunk anyway on my MR2, so I might as well put that empty space to use.
I think this would be cheaper than a full EV swap, since the A/C and hydraulics are still powered by the car’s engine. Just the motors, relevant controllers, and a small battery pack. With regenerative braking and a big turbo alternator, I could have on-demand AWD.
Oppo, tell me this idea is too much. That I’m not qualified for a project of this magnitude. Talk me out of it. If it’s not silly , I’ll seriously do it and post all the crazy adventures here on Oppo.

This is very silly and not doable for people who don’t own shops. But I like it

I don’t own a shop, but I do know an EV conversion shop that I could gain access to...

I love your Mr2. That color is beautiful on it. Shame that parts are NLA, because it could be a keeper for life otherwise. No advise on your e-conversion, but I’d probably just love it for what it is.

So your logic is that replacing/augmenting the subframe is difficult and converting the car as described somehow makes more sense.
I’ll discard that argument for you as we both know it’s bullshit.
So explain to me how regenerative braking works and how you’ll implement it without the cost of 5-10 subframe repairs alone.
No. Yes you’re really smart but no.

I’ll probably keep it for life regardless. It drives fine now that it’s got an adjustable coilover setup (allowing it to get a proper alignment despite the mangled subframe) and it’s incredibly reliable. I love the car and it never gets boring.
The idea of adding AWD just sounds delicious though...

Make it dual-engined with a 2ZZ in the front!
I’d just get the damaged portion replaced and rock on. I don’t think a hybrid system would fit the car...in fact, extra weight over the nose might not help its balance.

Appreciate the directness, but I feel like I need more convincing... This one’s right on the fence between bullshit and brilliant to me.
I could explain the implementation and formulate a budget based on those projections. Could even do some calculations and outline the programming for a torque-vectoring setup to be integrated with a custom ECU so the whole thing runs smoothly. But...
Maybe there are better uses of my (and my car’s) time? Autocross, more reasonable upgrades, etc.?

Mmm... 8 cylinder MR2.
I’m thinking the extra weight up front would get it closer to 50:50 in distribution. I can put the battery pack in the back too to offset the motors up front. Then again, fixing the subframe would probably be cheaper.

What would you use to coordinate power between the front and the rear and between the two motors?

Ooh, glad you asked.
Front motors would be geared directly to redline at around 85 mph. No real desire to go faster than that. Would be connected to the same accelerator pedal as the gas engine. Once calibrated properly, they could work together to provide equal acceleration. The low-end torque of the electric motors would allow for such a single-ratio setup to be effective.
Between the two motors, current would vary left-to-right based on steering angle. This would provide rudimentary torque vectoring, a-la Acura NSX.

It’ll be heavier. The extra on/over/in the front wheels will ruin the handling. It won’t be faster, more delightful or in any way improved. And it’ll be off the road for months while you a trying to make it all work. These are months in which it could be driven.
Your car is not broken. Just repaired poorly. Fix it properly then decide if you still won’t to go down this path...

A custom designed subframe that allows for electrical motors for the front wheels that fits a Toyota from the 90's? Price that out and you’ll have all the convincing you need.

I think if your going to reengineer the front suspension why not go all out with inboard shocks. I mean all of this won’t be cheap and for the money you could make something more unique than an awd system that makes the car heavier and potentially worse.(lower top speed, less hp from the gas motor because of its extra alternator, the inevitable months working out kinks and glancing at your fire extinguisher every time anything happens)

If you’re gonna go through all that, why not just fabricate another subframe?
