Heheh, anyway, I would go turbos. Of course I did all mine at once but if I had to do them in order then always 'go' (and stop) before 'show'. Then again your Z is so nice I would probably not want to put too much strain on the engine by going with bigger turbos so that's also something to consider. Basically what I am saying is that I dont know but good luck in whatever you decide! ;)
