2ZZ Swap. Why? Why Not?

[daewoo01]

The 2ZR Swap, is obviously very popular, but it is really even a swap, or just bringing these cars up to the Spec of what they were sold with in Europe and Japan, and should have been sold with everywhere?

The 2ZZ Engine seems a much better 'swap', as it starts with 189Hp/141kW compared with the 2ZR engines 138Hp/103kW it starts with an extra 50Hp/40kW.

I understand that it's a much more difficult swap, and requires modification of the chassis, but why isn't this swap more popular?

Did it become more popular, but just isn't publicised as much?

The 1ZZ Engine is more common, but has similar power to the 2ZR, which I guess explains why it isn't a more common swap.
