What is the purpose of having a motor in a street car that can rev to 11,000 RPM?
If you want a fun car, why worry about high revving, low displacement motors and go with something that will give you a truely fun car, like an SR20DET, or if you are stuck on NA, go with the aforementioned VQ35.
I have driven an S2000, and personally, it wasnt really that fun of a car, simply due to the lack of a low end. This is basically what you are looking at. If this is what you want, good luck. I will be way ahead of you with my TT V12.
