As a cobra owner, I don't like fauxbras, unless they can back up the look.
If you put a cobra motor, suspension and brakes on to a GT or V6, it's all right. If you use a stock 5.0 with aluminum heads and an aftermarket, cobra or GT40 intake, it will pass for a modified cobra.
If you use a stock 5.0 with stock heads and intake, that's not cool, just get a stalker body kit or something. If you use a stock V6, you are only fooling yourself.
This kind of foolishness is what makes ricers think a civic is fast.
There is no shame in owning a GT, a GT is bad @55, it's easy to make a GT as fast as any cobra, shouldn't that be the first priority?
