Re: fiat punto sporting GT cams are not suitable for a Sporting. You want a Supersprint Manifold and full exhaust, GSR induction kit and a remap but you'll be lucky to see 15bhp gain even on a healthy engine.
Uprating the leads and skimming the head is pointless. As is tuning a Sporting. They're already quite "tuned" from the factory turning out 85bhp so not many gains to be had.
General concensus is buy a GT.
