Good lord...
What else would you need to do to the car in order to have this on their reliably?

That is impressive. Maybe after my warranty expires, but I want that badly.

Forgive the newbie question what exactly would a bigger turbo do would it increase the base pressure i.e. PSI of the turbo or would it be able to maintain the current 21 PSI that that the stock turbo is tuned for but be able to hold it at higher rpm's?

Why did you sell it!?
I wanted more power without having to do a turbo swap or engine work. Whenever you do stuff like that the car is just never the same.
Intake, and tune on my 5.0 and I'm riiiiiight at 400whp

Plus my dad had 5.0s when I was a kid, and I've always wanted one. Got a great deal on a 2011 GT premium

The latter in most cases as long as it doesn't max out the injector duty cycle while shooting for 11.7 AFR. I think an aftermarket FMIC is a requirement for the turbo upgrade.

A bigger intercooler and piping would definitely be something you want here. If you're gonna spend this much on a bigger turbo why half ass it.

Agreed. And the ATP turbo comes with the upgraded charge pipe already anyway. I would go with a full 3" turbo back (not a 3" DP that necks to 2.5") exhaust, upgraded IC, upgraded all charge pipes and definitely upgraded intake.

the trick in something like this is to upgrade to a slightly larger turbo, not a monster turbo. thats what i did with my WRX, from stock on 2.0 to evo III 16g wihch was a stock turbo on the 2.0L evo i think.

something that comes stock on a 2.0l turbo car would probably fit the bill best. or an aftermarket turbo designed for 2.0 applications. the bigger the turbo, the more HP you get out of it, but often as you increase size, the boost comes on later and later and when it comes in its like a rocket, which may sound fun but it can make driving the car a chore as all of the sudden your wheels start to spin and the car becomes difficult to handle, especially in a front wheel drive car.
