If you already installed a turbo, you already have a turbo car. Now doing a WRX swap on top of that makes less sense because you're adding expenses. Even doing a WRX swap in the first place isn't what I'd have done, since a WRX of the same year is readily available, stock form, in the used market.

I guess I'm unsure what your goals are. Are you happy with the turbo'ed car? If not, why not? If you want more and more power, for example, almost invariably the answer is going to be get a factory turbo 2.5 car etc. as far as I'm concerned.

im only boosting 5 pounds. dont wana boost alot till i get better fuel injectors. barely feel it
Even if you try and boost more with bigger injectors I don't see you making much power. You'll make more than stock but the N/A 2.5 isn't designed for boost. Or they would have put a turbo on it from the factory. A WRX/STI swap is a logical choice, but it's going to get expensive. On the other hand, you'll be able to make significantly more power with an EJ255 or EJ257 under the hood. They are designed for boost, where as your current motor, really isn't.

Do some math and see if you part out the turbo kit, sell the car as stock, and sell any other parts you have around, how far you'd be from buying a WRX.

What kind of turbo swap did you do?
+1 this would be helpful. But why did you do this in the first place? It would have made much more sense to just sell the current car and buy one designed to run a turbo...
