Ok, let's compare low end torque on the KA and SR - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

You can't simply claim revs means more power. The engine is only part of the equation. This isn't something I've really looked into specs on (basically, I don't know the gear ratio between the SR and KA trannies), but more revs on a car with a lower gear ratio simply would mean the higher reving engine would turn over quicker than the the lower reving one with the same power going to the wheels (assuming similar torque and hp curves). With this in mind, it's a poor generalization to state a higher-reving car will have better power delivery. With some cars, it may be true, but it can't really be used to generalize all cars.

It'd be great to have a car with great low end and top end power. Here is the only real place where more revs will give you a consistent advantage. You'd be able to get great performance off the line with a higher gear ratio, letting you reach higher speeds in all gears.
