turbo upgrade

[vwturbo]

2001 VW 1.8T
nasira yung turbo ko last week, I noticed a drop in boost then after I was not getting any boost, zero and I hear a grinding noise, sabi ko **** sira yung turbo. I went home then started to take apart my turbo after cooling her down.
here is the picture of the busted turbo
the shaft turbine would would move in and out with some bent fins and there was a oil in the turbo inlet pipe, - busted seals.

driving impression
1st test drive with the stock n75 boost valve, I was spiking 21 psi, 13psi to redline (I'm getting 17psi boost spike with the stock n75 boost valve and stock turbo)

2nd test drive with the n75 J boost valve(race valve) spiking up to 24 psi, boost spoolup starts early at 2000rpm, peak power around 4000-6000rpm, gobs of torque
