I'm trying to think what else...?

A stud and bolts for the O2 housing, they might break...

Oh yea and make sure to get some PB Blaster and spray down the manifold to turbo bolts/stud and turbo to 02 bolt/stud atleast a day before you try and remove the old turbo.

u dont have to get the 17 psi one. ur stock t25 only runs at 12 boost and 11 when it hits the intake. ul be running and increase of 5 boost. i would get some hardpipe intake and probably a new o2 sensor since that will probably break. You might need to upgrade your injectors and ignition, and make sure your BOV can handle 17 psi. and if u do replace it.. listen to nate about the PB Blaster (USE PB AND NOTHING ELSE IT WORKS BEST!) other wise ul be cussing alot. prepare to get bloody knuckles to!

cool thanks for the links and all the help.
