Turbo Tips and Engine Quips?

[GnarGnar-YarYar]

THE TIME HAS COME!(dramatic music) to build my HATCH!
Alright so Ebay has a t25/t28 for originally for the Scion XB but i did a little digging and it works on a 1.5L 1NZFE Engine so it should fit my 07 yaris hatch??
just double checking here? OK now if it fits im going to only set the thing to about 7 or 8 PSI. Now can my stock engine handle this beast? ive searched high
and low and the best i can get is numbers on HP.
ALSO besides haveing to edward sissor hands my bumper am i going to need to do anything else to accomidate the kit?

Next Im thnking exhaust give the girl some breathing room any ideas on size? im thinking a 2.5-3 in?
IF all gos well and shes dynoed and tuned, and a short shifter theres not much more to do to the engine....or is there?
