HX COMPARO

UPDATE: for anyone that comes across this: the reason the turbo failed was due to oil starvation, if you look at 1:51, the 90degree fitting sticks in too far into the check valve, so when the valve would open it would touch the inlet of the 90deg fitting and not allow oil flow. I just discovered this by damaging another turbo, then realizing why.

Comparing a good HX35 with my HX35, I still do not know what may have caused shaft play. the good turbo has been running with a .045 restrictor, mine has been running with a .052, both engines put out same oil pressure, my turbo does not have any leaks (nether charge pipe nor exhaust). I dont really know why the shaft play is so much, I bought the turbo BRAND NEW never used.

If engine is putting out 100psi of oil at most, what restrictor size should I be using?

it goes right on the turbo inlet.

I have 1/2 inch return line, with a scavange pump sucking the oil out.

where do you install the oil restrictor? at the beginning of the feed line? i'm planning on going turbo sometime in the next year, just doin some research.
