Personally i would go with the blower, twin turbo's would be nice too but they are a buttload of money. You can det a kick ass blower for 3K, or even cheaper used. I would go with either a Vortech or ATI procharger, the ATI comes with a air to air intercooler, my friend has one on his 99 Cobra and it runs damn good, he has a Vortech S Trim on his 96 Cobra (Lucky ****ing bastard, he traded his 99 ning on a new Vette)
