May I make the distinction - we are talking about these turbos:
(as listed on garrett website)
The -5 :
GT2860R 707160-5
The -7:
GT2860R 707160-7
The -9:
GT2859R 707160-9
NOTE^ GT28*59*
NOT:
not a GT2860R -9.
GT2860R 739548-9
This is essentially a GT2860RS (you'll note the cartridge numbers are the same).
So when people are referring to -9's, they mean the GT2859R -9, not the GT2860RS-9 disco potato.
Some confusion in this thread with turbos names/numbers/chras.
