Turbine wheel to housing issue!
I have a T3 turbine housing 20358-72 with 0.63 a/r housing. The original Turbine wheel in this turbo has a small wheel, too small for the housing its in. The housing has about a 2" exducer and a 2 3/8" inducer.
The issue is that the current "standard" T3 turbine wheel for this housing is exducer: 1.802" 45.77mm and inducer: 2.324" 59.06mm.
So there is a large amount of room between the wheel and the side.
Question 1: how much room should be between the wheel and the housing.
Question 2: Looking at a T04B standard wheel (# 451311-0014) it seems to have a much closer fit with exd: 1.914" and ind: 2.322". This would leave about one millimeter on each side of the wheel. Would this be too close?
Question 3: which turbine wheel is the correct one for this housing?
I have been looking online for days trying to find the correct wheel.
Thank you very much for your time.

I found out the information I needed. Turns out because the Garrett number is 430225-0013 for the "standard 0.63 a/r 20358-72" I have a turbine housing from a TB0322.
So turbine wheels 409646-0052, 409989-0072, 451311-0003 and 451311-0014 will all fit in The t3 turbine housing (430225-0013). And any of these will fit in the housing with only minor differences.
some of the turbos that came with this T3 0.63 a/r housing are
TW4B
TW4C
TO4B
So After I get the part needed I will have a T3 housing from a TB0322 0.63 a/r
and the T72 old style P trim compressor wheel with a .58 A/R housing. Which seems like I found the information I needed but wanted to make sure its available here as well.
