They weren't failures, they performed exactly as is to be expected form a natro 3L. Don't get me wrong 170rwkw is farken impressive for what it is, but not for how much it cost especially with no option of progressing.
Like I know I'm not making big power but the potential is there, whereas with this thing.... Well, ur at it's upper limit, u can't put nitrous on it cause it'll ping it's head off and you can't turbo it for the same reasons/u wanted an NA.
Just bad, bad bad bad.....
