The 1.75L turbo engine from the Alfa Romeo 4C, but coupled with a proper manual transmission. I wonder whether it would fit.

We know it will fit, but at what cost? Don't write off the 1.4 just yet. It's a great engine with lots of potential power.

No disrespect for the 1.4L intended. It may well remain a better option than the (obvious choice to me) 1.75L and other engines.

While anything can be made to fit, maintaining the car's inherent balance and nimbleness will always be paramount for me.

I will watch with interest as development continues.

I was referring to an factory option not an transplant,anybody know the weight difference between the 1.4 and 1.75.
Factory-installed is the only way for me. Good question about weight. Even if the 4C's engine weighs the same as the 124 Spider's 1.4L, ancillaries such as radiator and intercooler may be larger. Also worth knowing is whether transmission, driveshaft, differential, and halfshafts will need upgrading.

The 4C's engine is far superior, and is probably actually lighter. The 1.4T is a very very good engine, but the 4C's engine is one of most advanced engines made, it's basically a scaled down exotic car engine.

The factory put the 1.7 in the 124 rally car, I too wish they had invested just a bit more and made it the stock motor in the Fiat124....even if it arrived detuned for some separation with the up market Alfa using the same motor.

It has been noted the 1.7 uses different ECU and other complications but I am sure it can be done. In the prior generation Miata we have developed a collection of goodies to install a Mazda 2.5 liter that was only used in bigger Mazda front wheel drive applications, we make and use custom engine brackets and other parts and techniques to make the install nearly plug and play and that gets us a genuine 200 at the wheels normally aspirated with factory warranty on the motor, easily north of 300 hp with boost. We need to re-pin the intake manifold from the 2.0, use the oil pan from the 2.0 on the 2.5, delete balance shafts, and make other changes...but it can be done. So, installing motors never intended for the chassis is not something that phases us, I am confident the 1.7 will end up in the Fiat124 at some point even if the factory won't do it for us. Given the transmission in the Fiat124 is from the NC generation Miata, it might turn out that the 2.5 liter referenced above is the easier install, will see. In the meantime, already have the EUROCOMPULSION piggyback on the way and are deep in testing highflow downpipe prototypes and other exhaust goodies to see how far we can take the 1.4 liter.

The Alfa Romeo 1750 in the 4C is an incredible engine. I would love to see a kit to swap it into the 124. The 1.4T is a great engine, but the 4C's motor is in another league. The thing even has a 2 piece block like a high end Ferrari. I have no intention of making a conversion kit, but I'll support anyone who does.

I imagine most here (and most enthusiasts in general) would prefer a traditional manual transmission coupled to this engine rather than the DDCT used in the 4C. Is the existing 124 Spider manny tranny up to its added torque, or will a beefier unit (which may present packaging challenges) need to be found?

My team and I think the 124s manual will hold up fine with a 4C engine.
