I have never owned a 914. Starting to kick around the idea of getting one.

Wondering what kind of weight difference is there between say a 2.0 four cylinder car versus a modified car sporting a 911 six cylinder motor?

What kind of power can a hopped up four banger put out?

Thanks!

A 1.7 goes like a Prius.
A 2L FI is like a Gen1 Miata
A big -4 will have carbs and will likely annoy you having been spoiled by modern FI
A small -6 will have carbs and sound great, but will cost 10k
A big -6 is great, but holy crap the cost.
300hp is like a 911 Turbo
A V8 feels heavy.

I feel the sweet spot is ~200hp. 0-60 in 5.5s so it goes like a sports car. So I'm in the camp of a Subaru swap, 185-300 hp, modern shifting trans, easy A/C, low weight, no valve adjustments....

I really like my 200hp 3L Nissan V6, but it's not the easiest swap.

Not necessarily. Fuel Injection will work on a big -4, but it will require some patient tweaking. Aftermarket EFI would be better, but it requires tuning to make it work right.
