turbo over-oiling? will i need this part? jgs tools

[pacefarm]

hey everyone,

i searched a bit, but no luck. i'm in the midst of turboing my ka, planning on installing the oil lines next. i ordered the jgs tools oil lines, and saw what appears to be an oil restrictor for the turbo. i got a t3/t04e. here's the part:


"0.063" Oil Pressure Orifice
303 SS, 1/8" male to 1/8" female NPT, use thread sealant on all NPT connections.
$15
ONLY USE IF OIL PRESSURE GOES HIGHER THAN 50psi AT THE TURBO UNDER LOAD! IF THIS DOESN'T FIX OVER OILING, HAVE TURBO INSPECTED BY A TURBO REBUILDER."

i realize i dont have the ability or any-way to measure the oil pressure at the moment. but in general, those of you who do have ka-t's, do you guys use this part? is it necessary for a t3/t04e or how do i figure out whether i need it or not? i dont wanna ruin my turbo by not using a $15 part...

thanks in advance.
