So I can fit any p-trim turbine housing one the turbo? Thanks

 

Unfortunately there is a little bit of a gray area here when you are talking about an OEM turbo -vs- Aftermarket. The P-Trim is technically 74mm/64.5mm = 76 Trim, your measurements 74mm/64mm make yours 74.79 Trim. So there is a risk that an off the shelf housing made for the aftermarket P-Trim may not work on your turbo. The only way to know, since that part # and the measurements don’t match up exactly with anything aftermarket, is to test it and find out. The good news is your wheel is smaller, so if anything it will fit with additional space around the exhaust wheel. This, however, can affect response as the exhaust will technically be “leaking” by the wheel to housing gap. Maybe time to recheck the measurements? Could you in fact have a 64.5mm?

 

I'll double check when I get home and get back to you. Thanks for the help

 

Sounds good. No problem, that's what we are here for!

 

We're talking less than .020" difference, and be aware when measuring that the blades are not always 180 degrees apart, and will affect your measurement. I have no doubts about it being a P trim, but I have been wrong before.

 

Unfortunately I forgot the micrometer at work. So I'll have to measure it again in the morning. Yea I'm sure the turbine could be worn a couple thousandths too depending on how old it is. All I know is it came off a mustang.

 

Yep its measuring 64.3(which would probably be 64.5 if the blades were straight across)/74mm so I think I'll be able to fine a smaller housing

Yes, then it would appear you have a P-Trim wheel and that any P-Trim housing should work for you. Let us know if you want to get one moving. Thanks.
