The vitara carby is a do-able option. Weber carb if you have a spare $700+++ to spend, but I'm not starting that debate again

Not sure...if it were that easy I'm positive it would have been done 100's times before

Keeping the same engine, i think you'd only be talking about 5% difference in anything you do. But if someone has some lab tests that prove different it'd be good to see some results.

Because its a reasonable amount more work with minimal power upgrade. The best thing you can do with the 1.3 is not spend a cent on it other than basic servicing. And with the money saved invest in a 1.6 efi conversion.

Best you can do I reckon would be extractors, cam regrind, bigger jets or carby. Not much point.
I'd just save for a 1.6 conversion

The 1.3 does perform pretty darn well with a weber 32/36, 2 inch exhaust and extractors as well as a tweaked dizzy. You should be able to find a good nic s/hand weber up and running for ~300ish. If your looking for new stuff its mega bucks and not worth it.
Another alternative that quite a few yanks have done is fit quad ~32mm motorcycle carbs with awesome outcomes! I think nandor on this site has also done this with success.

i have 32/36 weber, just bought new 2 inch exhaust, once the rebuild is done and its all back together will let you know if you can wait, with just the weber & the extractors that was on it made more of a difference with responsiveness rather than a feeling of more power

you can do SPI pretty cheap if you can find the parts.

I couldn't even sell a new weber on here for $300... There cheap if you look around. But may not be the best choice for some types of wheeling..

There's been a turbo kit for a Sierra for sale in the Quokka for $800 (I think) for weeks now.
Just go the usual, extractors, bigger zorst, shit pod filter... Then give up and go for the 1.6
