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

[pimp my yaris]

This was the turbo I was using. You will find it by searching "GT25 turbo". If it has the word GODSPEED in the picture, stay away. There are several different sellers of this turbo. Or possible one seller using several different names. One thing I would like to note I was using a 1.5mm oil restrictor on my banjo bolt for oil line. I was doing some reading on Garretts web sight and found journal bearing turbo's dont need a oil restrictor unless they are blowing oil through the seals. The restrictor I was using was made for a journal bearing turbo.
But if you want less problems just buy the Garrett turbo and do it right. And read and follow all instructions on there web sight. I guess its possible the turbo failed early due to the restrictor??? I am not sure. I plan on going turbo again as soon as the weather allows. I am also going to get a Tig welder to buid my own exhaust and downpipe.
