Default 500whp G"LS"R Turbo options. Precision, Turbonetics, or Garrett?

Hey guys, I'm stuck on choosing which turbo to use on my car next. I currently have a forged piston-rod stock sleeve gsr. Precision 5431 inline pro log manifold 20psi 380whp.
I'm getting ready to install my css gsr block.. 81.5mm bore..Cp pistons9.5:1 H beams and LS crank.. ram horn manifold ...my head has type r cams with skunk 2 springs and retainers. I would like to make 500whp but I cannot decide if the precision 6262 will be too big for me or will It work good for a street/track car. Would you guys recommend a different turbo or size. Thanks guys any suggestions will be helpful.

If you are looking to stay with the Precision line and with a 500whp goal; I would use the 5558 or 5862 (or if you were looking to stay on the JB entry level line, the 5557 or 5931)

Thank you! I will look into those turbos.

I could be wrong but I'm pretty sure the 5558 has a JB option.

precision & journal bearing is a risky combination.

It does come JB or BB. What I was trying to say there was "JB Entry level" as in Entry level units do not come w BB options.
The 5558 and 5862 come with wither a JB or BB option

The would be ideally the TNX 30-60. If you'd ideally like some room to grow, then the TNX 40-60 would be next up
