Hoset 52 and larger compressor housings are much bigger than what is pictured...........
Not sure what you mean but this is a super 54 turbo from quadstar tuning
Not to ruin your day "that looks to be some hybrid." Having hands on "LARGE" Holset turbochargers "I can say without any reservation whatsoever the compressor on that turbocharger is not a compressor from any of the 50 series by any stretching of imagination or description." 50 series compressors are larger and have a distinctive large reinforcement block cast into it between the outer edge of the compressor body and compressor outlet.
No clue thats how it came from them and everyone else with one looks the same but its sold
It was worth it i had it set to 21 psi but i upgraded to the super 60 from quadstar i like the sound it makes at idle and is also great for the 6.5 and towing the 60 comes preset at 20psi
Honestly; I was confused at first because Holset 50 series and PRO series do come in small turbine sizes too but the compressor is massive....I finally caught on to the custom build and nomenclature used to identify the turbo............"old age I suspect."
I see in your sig you use a non-gated turbo w/blow off, big turbine or?
We run that setup both with and without external gates since there isn't one solution for every single truck that fits the bill. That particular one has a JGS 40mm external gate and we do those turbos with multiple exhaust housings and turbine sizes now. I'll update the signature to 2019 status!
Now that sounds good and has me interested too.................
I already sold it waiting on the s60 to come in now i haven't had time to update this post but i will. Or may need to delete it
