I had my Q50 in for service (just getting a wheel refinished that they gouged changing a tire) and my service advisor confirmed that in starting in 2023, Infiniti is sourcing replacement turbos from Garrett and no longer using Honeywell. So there are now three versions of the turbos:

Rev. A - Original with EGT Sensor (Honeywell) 2016 - 2019/2020
Rev. B - Revised and Removed EGT Sensor (Honeywell) 2019/2020 - 2022
Rev. C - Unknown revisions and changes (Garrett) 2023 - Present

We don't know exactly what Rev. B made revisions to. Removal of EGT Sensor for sure and probably seals.

Rev. C is a complete unknown at this point so if anyone can get model numbers from the 55-page long thread, we may be able to do some digging.

@silverr_q60 can you post your paperwork from the dealer that possibly shows turbo part numbers?

Not sure if anyone can make out any more of the tag. This is about as good as it gets from the cheap made in China endoscope I have.

Nice job posting that picture @Dzazter We might be able to figure out a part number from that. I can faintly make out some of the numbers and letters. I'm going to take a crack at what I can make out:

MODEL: MGT14472
GTX PN: 8899
GTX SN: Z0

It's not much but I played with this photo in photoshop and was able to add some contrast so perhaps one of our other members can make out more.

Did they happen to list a part number on your service paperwork by chance @Dzazter?

Might have a winner here:

I could definitely make out the first few digits of the model number and then started googling until I found a part number. It looks like they use these SAME turbos on the Juke as well. It's only 1.6L but with two of these that our car has, each side is only feeding 1.5L of displacement.

Nice detective work everyone!
