Technical bigger garrett turbo gt 1446 for standard punto

[icecream]

Hi Guys,
I bought a new 2012 punto 1.4 turbo multiair (99kw) in South Africa. They don't do the abarth here, unfortunately! I had it already remapped and it goes nicely. I have been reading that abarth changes the turbo to a larger garrett gt 1446. Can I add the bigger turbo as well. Has anybody done this already and how much more extra power did you get? Is it all worth while??
Thanks for your help

Basically thats the only difference engine wise other than the "map".

The Gt1446 is pretty expensive and has an AR ratio of 0.46 (correct me if I'm wrong) but I know the bravo 2.0 Mjet uses a garrett as well but has an AR ratio of 0.49 but will more than likely need a bigger flange on the manifold. The standard AR ratio is 0.38.

Have fun with that
