heres pics of the gen 3 finished if it was my own car cost all up would be $5000 tuned, excluding labour for making everything etc, so if u can do a bit of fabricating welding etc, u can have your car turboed and tuned for round the $5000 mark

what size is the rear housing outlet.. basically though a turbo will always run better with the biggest dump pipe you can fit on it.. 2.5" is pretty small.

but also u dont want to big morgo, pretty much what ever the rear of the turbo is, normally surfices, cause what happens if u go to big it doesn't have as good flow! look up on the internet about airflow and dump pipes, heaps of info in there
