You take an engine made for 250hp and push it up to 380hp vs an engine designed for 380hp right out of the box. Which do you think has better reliablity?

We are hitting the ceiling for the S4 engine at 400hp. Even with bigger turbos, I figure mid 400s. That is almost doubling the output. The RS4 engine is already sitting pretty high, a slight bump to 450 is only about a 20% increase.

Plus, nice recaros, air leather or alcantra steering wheel and shift knob. Bigger brakes(?)
