I would say yes. It is a small high rev engine. That's where it makes it's power. I don't have a first gen but I do know when I am pushing 150+ miles an hour it is sitting around 5000 rpm. And 4500 is much slower. The difference between 4700 hundred RPM and 5000 RPM is the difference between 150 miles an hour and 163 mph.
If it is high It's not that far off. And it certainly is not indicative of where the car makes power.
