Looking to find out any info on this turbo.

Did some research and think it's a ball bearing 54, but does anyone have more details on it? When this turbo came out, expected hp output, TC stall speed that works best, etc
 
If its an old Pt-54 it would be a cast wheel 625 hp rating turbo, needs a 2900-3000 stall good for 10.60s all in,
would not be ballbearing , came out pre 2005 , should be a 59mm compressor and 62mm turbine

If it is a PT54 those came out in 2000 I believe. I thought it was the replacement for the 61 at the time. Heard it was a good turbo as well.

Hello everyone.
PT54:


Journal bearing only, E compressor cover, non ported shroud, with a 3" inlet, 2" discharge, had a cast Garrett 60mm 60 trim compressor wheel 2.320" inducer, 3.00" exducer, Garrett T04 69 trim turbine wheel 2.920" inducer, 2.420" exducer rated at 620 flywheel hp, needed a decent 3000 stall converter and was capable of mid to high 10's if pushed hard. Typically came with the .63 A/R 3-bolt turbine housing, but was also available with the .85 A/R 3-bolt turbine housing too. Although very rare though. It worked good with ported heads and a cam, an old school 16930 spooled it good with the .85 housing and even better with the .63 housing. Kinda fell between a PT52 and an old school 60-1. It essentially went away once the billet wheel technology came online around the 2006-2007 time frame.

Hope this helps.
