Nitrous is the easy and cheapest way to do it with out a doubt... otherwise like everyone else said its going to be a LOT of cash.

uhhhg helps if I can spell nitrous.

you'll need more than 300hp to beat a cobra...an 03/04 mostly

Don't forget the tin can muffler and 6 inch tip!!

But seriously, my bone stock Cobra put down 260RWHP. Your GT is probably looking at 220. To get above 300 N/A without a lot of money will be tough. Your best bet is save your money and do it right... be careful of detonation on the stock engine... it wrecked mine.

full bolt ons and some juice will get you well over 300 rwhp

full bolt ons and a supercharger will do even more,

stock with a charger would be the cheapest bet, but with the bolt ons, you'd benefit even more

but like everyone has said, maxxing out the motor N/A is gonna cost as much as at least 2 of these combined
