^ why a green is a good turbo for the wrx, the sti is a 2.5 and can push a bigger turbo!

Since you didn't mention what you want out of the turbo setup, ie: boost threshold, power levels. I will go off the two you mentioned, and say GT3076R. Really you need to tell us your goals, and if you can build a motor for your setup.

A Polka Pickle would probably be the most cost effective way for you to achieve your goal, but if you had the cash you could definately do a GT30R setup and run a very conservative tune and still be making your 350whp goal, with looooaaads of headroom for whenever you want to make more power. If a GT30R setup is too rich for your blood, a polka pickle + meth would make you a happy happy man.

If you want 350whp I would go with the 20g. Even though you said you didnt want that, that would be the cheapest and most reliable. Fyi the green and red are both 20g's. Forced performance has red and green set up for number chasers. If you drag this car that is probably the turbo for you. I am more of an autocrosser so I chose the normal fp 20g. To get the most out of the rotated kits you will need to do the internals, and if you drive this car on the streets, emmissions come into play. It is alot easier to put the stock dp back on a 20g than a rotated. It all depends what you are looking for. Good luck!
