Just imagine this thing with a turbo M20 in it

It is technically not impossible, and I can't imagine a cooler way to die.

Well, what are you waiting for???

Actually that small and I assume light, why not a turbo M10? Might fit better, still be 2 or 3 or 4X OE HP and lighter.

It'll need better brakes.  🙂  Actually, installing a straight six may be a little difficult without extensive modifications, the engine compartment of a model T is pretty short.  I assume you've seen the Model A with a Cosworth BDA engine that was built so it looks stock to a casual observer some years ago: https://www.thedrive.com/news/37877/thi ... rth-engine

I'm enough of a purist to have issues with cross-brand engine swaps. That needs a turbo 2.3 out of a Turbocoupe.

In general I tend to agree with you but #1 it seems like half the antique cars just have SBC's in them and from all I remember that 2300 engine was just a turd, even with a blower on it. To me this would be so unusual and interesting I'd make an exception.

The fact that so many have an SBC is why I've become something of a purist. People assume I'm anti-GM.  I'm not, I've had a Chevy in my life for a long time, I'm just bored to death with seeing 350's and now LS-family engines jammed into everything. 

The turbo 2.3 wasn't awesome but a lot of that was the slow turbo.  Once it started spinning it did fine but they majorly suck off the line. A better turbo, or even a ball bearing upgrade in that old T3 would make one a lot snappier.  The EFI setup they used also wasn't totally awesome.  Toilet flapper air vane meter.  A real mass air sensor would remove that restriction. Ford had real mass air sensors back then, I don't know why the turbo engines got the flap. I think the very last ones had a real MAF and an intercooler. As usual about the time they fix the problems they stop making it.  About the only other Ford turbo engine option is an Ecoboost.
