turbo gsr ?

i am looking to start building my car this january and
i wanted to know what would be a reliable turbo set up
to put about 250 horses to the ground for everyday use.
and also i wanted to know any precautions i should take
making the engine strong enough to run like this every day
because i drive a lot and i don't want the engine to blow after
15,000 miles

that was my point of view when I was first starting out... only wanting mild gains from a turbocharger but still keeping it streetable... my opinion, build it up so it is good for some serious boost levels so when you decide that 7 or 8 lbs or near 250 whp isn't good enough that you are able to crank up the levels without blowing anything up... as far as turbo kits that will achieve these numbers that you want, you can look into revhard, drag or possibily greddy... depending on what other mods you have going on your ride you should be able to reach the 250whp you are wanting... good luck.
