Just my opinion but I think new Cobra owners should be patient and wait before doing engine mods to these cars.
Not saying it can't be done, but to me if you're spending $35K on a car and have 360 hp, what more do you want unless you're really into drag racing ? A car this expensive isn't worth the risk of blowing it up and going for a rebuild.
Either way- I wish '03 Cobra owners luck with their new cars.
