GT4202 Journal Bearing Questions

I know a few pullers run em (or used to). What kind of boost/power are you guys seeing? I have one for a street truck that I'm going to be using nitrous on (wastegated housing) just curious if there are pressure ratios I should be avoiding.

Is it a GTA or just a conventional nut on shaft?

If it's conventional, abuse it! They can take some crap in comparison.

Conventional. I know the wheel isn't up to today's tech, I'm just hoping it doesn't die at 60psi on spray.

Meh. They'll live. The thrust is steel in most though. Good and bad. Tough but if you severely overspeed or lose lubrication they tend to weld themselves to the collars in a hurry.

Any insight on potential non nitrous power? 50psi sound good? Or can they take more?
