it depends on your goals you need to chose your goals and then decide what parts to buy not the other way around. the amount of nitrous depends on compression and tuning experience and the redline depends on where your cams stop making power, it's pointless to turn a engine 11k when it stopped making power at 9300.

and a blueprint just means you have all the clearances of you engine on paper so it doesn't mean crap just have it balanced and be done with it.
