2020 Civic engine into a 1993 Civic ?

Just wasting time, and was wondering what benefits ( if any ) you could get by swapping a 2020 Civic engine into a 1993 Civic.
>I would imagine the engine produces less pollution. ( ding ! )

> Since the old car is 400 lbs lighter, it would get better fuel economy.
It looks like thr 2020 Civic gets 42 highway.
That is the same as what I got stock in the 1993, but the old car is lighter.

Oh and the thing I could care less about - power.
POWAHHH BWAHHHHHHHH.

The engine in the '93 is running fine.
I'm just daydreaming like always.

I would imagine swapping in the new engine would be a nightmare with all the under dash wiring changes.

And since I'm asking, how about a hybrid swap ?
How hard would that be, and whst benefits would you see from that ?

Sounds a K20 swap. I don't know if you would see much of a fuel economy gain. The necessary transmission swap would mean much shorter gearing. But you could definitely see 155 HP from a K20 (stock), which is maybe 60 more than your car had in 1993. But an L15 engine out of a recent Honda Fit would be 130 HP and prolly much more eco-friendly. Cheaper too (at least for the engine).

My first thought is, will it fit? The civic has gotten bigger since your car. Does that include the size of the drivetrain?

That's a question I had too.
I just assumed it was the same size block.

I would bet it is a little bigger, being a 2.0 or 2.4 L block and a 6 speed manual transmission (I assume you'd want). But they fit. All you need is engine and transmission mounts and companies like Hasport sell them for the exact purpose you are daydreaming about. This is a known thing. Got $10k to spend? In a few months, with some significant labor, you might have a working k-swapped 5th gen Civic in your driveway.

Here is one of the legends of Honda racing mods trying to do it for just $3k (four years ago):

Even though a K swap is doable, the smaller engine out of a Fit would be more suitable if you were mostly looking for a practical option for a modern replacement engine without any high-performance goals.
