Help me ID this T3 upgrade

[volvero]

When I decided to send my Garrett T3 turbocharger to Turbodal to be overhauled, the shop manager said to me that the stock compressor wheel looked TINY and he persuaded me to install a bigger compressor wheel. The fact is that he never told me what the new spec was but the new compressor wheel is definitively bigger. They enlarged the compressor housing so that the inducer is flush with the big diameter of the compressor housing outlet.

Can you guess what this new wheel spec is? I know is difficult from a picture but let's give it a try.
Thanks in advance.

why dont you ask the shop that did this?

 

[volvero]

I did ask but they never replied to me, then I forgot. I just want a quick advice on what it shoud be like now....maybe a T4 cold side?

It looks the same

No. But I can tell you that you should change your boost reference point.

Measure the wheel. That's the only way to tell.

+1 you should pull the signal from the manifold

No. That's also incorrect. Pre TB, Post IC.

NO, that T in the hose is just how they gave it to me after the overhaul. I installed a MBC in between. (compressor outlet-->MBC-->wastegate)

 

[doucheNozzle]

No. You don't want your boost reference to be the compressor outlet.

 

[unionsmw]

dumb question, but why not the outlet of the compressor? fastest acting, safest boost control should be there....

 

[doucheNozzle]

You really think air takes that long to move in such a small area (the vacuum line)?

 

[FunkyStankyChicken]

so why is the compressor outlet a bad place?

Nice write up. Anyway my boost is set at only 10.5 psi with only 0.5 psi spikes at WOT so I feel comfortable with that setup.

Ok, I measured the compressor wheel inducer: 1.9 in. Don't know about the exducer. So maybe this thing looks like a T3 Super 60???
It's currently not in the car because I've foung a big crack in the wastegate port.

i was talking about for the boost guage not the boost signal....to clear up the confusion

Yes, Boost gauge is supposed to take signal from the manifod.

Need to precisely measure (A) and (B):

compressor outlet is not a bad place to pull boost reference. looks like a 60 trim t3 wheel, but without any kind of measurement, it's hard to say.
