Here's a breakdown:
* Mk4 Golf GTI: The 1.8T engine was turbocharged and produced significantly more power than the naturally aspirated 2.0L engine.
* Mk4 Golf (Standard): The 2.0L engine was naturally aspirated and produced less power than the 1.8T engine.
So, while both engines were 2.0 liters, the GTI engine was a different type of engine with more performance due to the turbocharger.
