I don't believe redline is different on any of the models. They all peak at 7500. I believe the difference that you are referring to is where the HP peaks.
I you're planning on doing a lot of mods, it would be kind of couterproductive to buy the Nismo. It has a little more HP and a slightly tighter suspension, but if you're going to drop it and basically change the suspension, get a cheaper model and spend your money on mods.
