Want to build costom turbo kit. Need advice from boosted guys!

[pimp my yaris]

Update: I ordered a front mount intercooler and 2.25" piping kit and also an additional piping kit as well and a adjustable bov that can be piped to recirculate. And a oil feed line with t fitting to tap into pressure sensor. This size should work well. My turbo,T/B and air box should fit 2.25" silicone connectors. I am going to try to use the stock air box and mass air. It may cause problems with fitting intercooler piping later though. I also have a question guys> Where are you tapping into to get your coolant for the water lines on the turbo?? I am thinking heater core lines would be the most obvious choice. But Im not positive.
If anyone is intrested, so far I spent 876.99$ including shipping
