You don't need a lot of aftermarket support to make the SR perform like a K-series. The K series is awesome tech. But the SR feels more brutal. Best way to describe it for me is: The SR is a shovelhead harley, the K is a CBR. But that doesn't mean that the K is more fun to drive.
I think it is too bad the 20VET never made it to the USA in a sentra. Hell, they could have used it in sooo many models. Rogue, Spec, Murano, Altima. It would have been a game-changer for sure. The aftermarket would have blown up around the VET engine.
I really wish the tech for nissans was as good as the K though. The QR25hr is a great motor as well. Worked out pretty much all the kinks with it. QR20VET would have been really interesting
Well, that was a tangent.
