I would just leave the stock valvetrain unless you change to a more aggressive cam setup and then do it all at once since it can be done in the car. I have seen people running n1 cams rev to 9500 every day and have no issues. Like I said 8k all day and a few blasts a day to 9k plus won't hurt anything. I know it is piece of mind to some people but to me if it worked for Nissan, it works for me. The ramp angle on the N1 cams is not very aggressive which is why you can get away with revving so high with lower spring pressure. I wouldn't run 20v outer springs either since it is just an extra thing that can go wrong when installing. Keep things as simple as possible. The ecu you are looking at is perfect for your setup. Just have a rev limiter set to anywhere between 8 & 9k and you should be find and not ruining any engines. I know once it happens to you once people become a little paranoid but with a simple set up like I suggested, you have no need to be. The simpler the better. Also, not sure what header you are running now but a good header is key to making good power on a simple setup like this. A 20v header is a nice option or a JMR as much as I am a Jun fan makes good numbers and is reasonably priced and since Stratton is the one selling them I wouldn't hesitate to buy from him. Tuning and header, tuning and header, tuning and header! I think I got that out of my system.
