yeh what are you after mate? The 3.0 V6 is power but no economy. The Hdi is reasonable power if you spend some money and you will have great economy. By taking an XSI and putting a few gti6 bits in it its not magically going to 'kill a gti6'. You are right with those mods are the best for the xsi but as Niall says without a remap and ecu etc then it wont work correctly and would be pointless!
If you are looking at a v6 conversion then its going to best the best part of a grand unless you can do the custom fabrication yourself. id recommend doing stuff with a hdi.
