These are now 17x9s&11s, but started life 30 yrs ago as 16x6s and they are now very light

I'm just replacing the brg cartridge and keeping the turbo at this point. It's brand new, so it should be fine once cleaned up and the cartridge is replaced. The failure was prolly caused by one of two things; something blocked the small oil inlet orifice allowing the brgs to fry or there was junk/dirt in the brgs from the supplier. It's a bullet proof Garret BB turbo, but was assembled by a third party distributor. I prolly should have torn it down before installing it to ensue all was well, but upon inspection outta the box it seemed good to go freely spinning and no play...
I'll post up more videos ASAP

Update
Just as we were ready to dyno it the new turbo's brgs went South
The turbo oil feed line, yes the one with a restrictor fitting, got blocked and turbo overheated smoking the brgs and causing major damage. Garrett has it now for a full rebuild and yes the restrictor fitting will be TOSSED when the turbo is reinstalled

restrictors are recommended on Garrett Ball-Brg turbos cuz they want oil sprayed on the brgs, not swimming in it, but my new set will be swimming
