T3 60 Trim vs T3 45 Trim....
So in doing some research this morning, I have come to a rather simple question probably, but one that I am not sure of the answer myself nor am I able to find the answer through searching the internet.
I currently have a 45 trim standard T3, with .42 AR compressor housing. I am looking to upgrade to a 60 trim compressor wheel, so I have been searching and came across these measurements vs my own.
T3 60 Trim Wheel-( the one I plan to purchase )
Inducer = 46.48 Exducer = 60.10
And my own wheels measurements-
Inducer = 40.48 Exducer = 60.10
The inlet (not inducer) on my current compressor is 40mm, since the Exducer measures out to be the same between the 2 different wheels, do I really even need to get a bigger housing if the bigger part of the wheel (exducer) is the same size as the 45 trim? Or can I simply just have my .42 AR housing machined at the inlet to accept the 60 trim's bigger inducer? If possible, how would this affect flow if any? If not do I need a ".60 AR" compressor housing?
Sorry if it comes off as noobish, searching for 6.5 hours only got me so far and I called ATP and a turbo repair shop/seller in Texas to not much progress I decided it was time to come here...
