NA engines are good fun, as they usually have a higher rev band compared to a forced induction engine. But power production licks balls unless you start to really up the displacement.
Turbo's on other hand are efficient, due to re-using exhuast gases to spin up the turbine, high power production in smaller displacement due to compression. Down side is lag, but on small turbo's like k03/4 this is not a major issue. Then remember the torque production of a turbo engine
Oh and noise
Plus you are comparing a NA with hardly any torque, to a 150bhp engine with a considerable amount of torque in comparison, never understood how they could even brand it as a GTI in the UK market and how the 2.0 was so ghey. But the 1.8t is a good engine, its just a shame its never came with a ko4 as the k03+s lick balls in terms of grin factor IMO. Which is why a k04 will be my next step as I don't have deep pockets for a Garett or IHI.
