The problem of turbocharged engines will never disappear, or are at least not ready to :
- low redline (for european engines)
- bad throttle response
- turbo lag
- induction sound
I'd take a NA 2.0l I4 over a FI 1.6l I4, a NA 3.0l I6 over a FI 2.0l I4, a NA 4.0l V8 over a FI 3.0l I6, a NA 5.0l V10 over a FI 4.4l V8.
