It's not a case of them not being as fast. They just wouldn't feel as fast due to you not getting that big surge of power you get with a turbo engine.
But i'd take a V35 thats slower over any other skyline anyday. Much better built, handles better (stock for stock), brakes better, etc, etc.
I'd still love to get a 4 door.
I can never make up my mind. I will be getting a new car next year but it's too hard to decide.
