Had a problem already, not with the old stock motor tho. getting ready for TnT. I have been, street beating this all week. 6lbs to 16 with no over heating problems or any change at all. The only problem was traction over 16lbs of boost.
Until:I noticed a little white smoke out of the exhaust the turbo sprung a leak
after 5 days I thought it would hold up one more day, it was used after all $000.00. To replace $1,800 to $2,100 Replacement cartridge for my unit $600.00 to $800.00, rebuild kit for cartridge 
$150.00. I took it apart a couple days ago, should have the kit by the end of the week. Hope to have it re-built next weekend!!
This Video is at the point where it just comes in and hits 6lbs of boost, Blurry? I say the camera could not zoom out in or out fast enough
Just listen with eyes closed. If you do look notice the front ends stands up at that point as well. See ya Donhttp://www.youtube.com/user/dodgedivain ... ZPPRhLMT2E
