Malibu supercharge

http://www.andysautosport.com/product/detail?_p=RSMR00040400&_v=vmd00074 what do u guys think of this kit? Its for a buddy of mine, he is askin what kind of mods he should upgrade before running this kit on his car? im thinking just headers and gauges and catback exhaust? What else am I missing? Any info will be great. He has a 98 3.1 L i believe

you may want to also upgrade the cooling system cause i heard superchargers can produce excess heat
