Garrett Turbo question

How many psi of boost can the stock garret turbo handle? Also, what is the best compressor wheel to get for these turbos? Thanks

These things are happy at 25psi, after that start to lose efficiency and drive pressure becomes an issue.

If you upgrade to one of the billet wheels such as Diesel site's WWII, RiffRaffs wheel or BD diesels wheel you bump up the efficiency range of the turbo and it becomes safer to hit numbers in the low 30s

PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.
