Technical Abarth and NOS

[LinoBarreca]

Anyone knows if a Nitrous Oxide System can be mounted?

I was looking at the following:
http://www.holley.com/HiOctn/ProdLine/Products/NOS/NOSNS/NOSzle.html

I wrote them and they answered that the 6 cylinder kit can be mounted on a 5 cylinder engine (Abarth is 5 cylinder in-line)

I'd like to know if anyone already boosted with success his car.
And, if there's any expert here, what kind of problems can I have doing this.

Thanks in advance.
