Turbo getting too hot?

[ze12o]

Recently sent my turbo to Turbos Direct in TX. They had their techs open the turbo up to inspect it. The guy calls me and tells me the turbos getting too hot and he said to get it better cooled or it wont last another 1500 miles.

I daily the car but not far and rarely push the car but when I do I really push it.

Here's my routine:
Start up
Warm it up til operating temp (via oe water temp gauge)
Wait til oil press drops to <60psi
Shut down
Drive out of boost for a few mins
Turbo time for minimal 1-2mins Hard drives 2-4mins

Setup:
93 s13 ka
Garrett T3 GT35R Top mounted

Water cooled (lines running from throttle body)

Oil:
Skulls and bones Oil block -->
-3an ssline -->
Earls -4an inline oil filter -->
Turbo -->
-10an drain

Ebay -8an oil cooler (not sure the size)
Trust GREX oil filter relocation block w/ thermostat
-8 oil lines

Koyo radiator
Stock clutch fan w/ shroud

Down pipe wrapped
Turbo blanket

Soon to install a nismo thermostat - water and oil temp gauges.

Any tips or recommendations would be greatly appreciated
