I was thinking of giving the 03 cobra a 125 shot of nitro for those times when you really need to leave the competition behind can the 03 cobra handle the extra boost i dont want to blow it up
Sure, as long as you have a good tune designed to handle the extra fuel you'll need to use along with the N2O. Lot of guys run a "flip chip" with one setting for their street tune and the other setting for the juice. Keep in mind a supercharged engine with an intercooler like the 03/04 will actually make MORE than 125 HP on a standard 125 shot. The added cooling effect N2O has on the intake temperatures crates even more than the rated jet size. Lot of guys run very small shots (like a 50) and see almost 80 extra RWHP from it.
