I'm no stranger to the simplify, then add lightness philosophy; just ask my missing radio, AC, PS and all the interior behind the front seats. I just don't see the 5lb saving as being as impressive as the increased performance of the turbo. I'll take a "free" extra 100hp over losing 5lbs any day.
I noticed you said similar performance again. I'll give it to you that performance was similar in steady state to the GTX line for the first gen EFRs like the 6758 but not with the 7163. The 7163 is like a 6758 that makes 100hp more at no cost in response. If the 6758 was similar to a 2871/2867/3071, then the 7163 definitely beats those by a significant margin and is not similar in performance.
Guess I'll just have to slap one on, make 400ft-lbs 4k to 7k and watch jaws drop
