hi, my old Garrett T25 the stock one that came on my blacktop sr20det, went bad. so i replaced it with the ISIS t25 replacement turbo on enjukuracing.com i also got the line kit. got everything installed and the turbo smokes. been driving it for a week and still smokes from turbo area but not out of the exhaust, spools good etc... the one thing that i noticed was the compressor housing moves pretty easily. where the c clip is. is this normal or bad? and the boost was spiking to 15lbs but the actuator is suppossed to be set at 8lbs from the factory. How would i adjust it down to 8lbs. thanks

The compressor housing should be tightened so it doesn't move. It probably comes from the factory loose so you can move it to where you prefer (guessing here... it shouldn't move once installed though). As long as all the lines are installed correctly, and the center section is aligned correctly (see garrett's website for proper alignment instructions), then it shouldn't smoke long after install, if at all. Not sure about the boost spiking issue, but Isis is a chinese imported brand, so it won't be perfect.
