Nitrous with the stock turbo
 

I know alot of people who have a turbo get nitrous to help make a large turbo spool up faster, so what exactly would happen if you used a 35-55 shot on a Gen Coupe with the stock turbo? Would it spool almost immediately, even though it spools pretty quick already since its a small turbo?

You'd be in the next gear too fast to shift if you used nitrous before 3rd gear. Probably before 4th. The stock turbo already spools up immediately. If yours isn't, you must not be tuned. For the cost of a 16G upgrade, I wouldn't even consider nitrous - go with a 16G upgrade from BTRcc. I think their kit (including tune) is running a huge special right now. I can get you in contact with someone @ BTRcc if you're interested.
