Did my Head Gasket Blow, or my turbo?

[webshell]

I just got my GS-T yesterday, everything was fine. It boosted up fine in all gears. today it was smoking white everytime i switched a gear, and only going to half boost. The car cut off while i was driving it and wont start back up.

Going by your "colseum" post, it sounds like your head gasket -at least- is toast.

You can't run any motor without water. An aluminum-headed one even less, and turbocharged even less than that.
