SP/PT61 turbo, did I get the right one??

[becauseican]

I just got my turbo from SP yesterday, I ordered a DBB pt61 with a P trim wheel and .58 turbine housing (its going on a 1JZ). Anyways I took it out of the box and noticed the turbine wheel was allot smaller than the last turbo I had with a P trim turbine.
The measurements of mine are 56.20mm minor and 63.93mm major. I thought a P trim was 64.5 mm and 74mm??, these measurements dont even match up with an O trim or a stage three wheel either. Also I was under the impression that the compressor wheel was a T61 wheel which measures 60.96mm and 89.92mm however mine measures 61.37mm and 81.96. Any input would be appreciated.

Randy:

Doesn't sound right at all.

Id be on the horn asap.

Also - IIRC......the comp wheel on that unit that you got is the GT35R wheel.

That being said, it makes me wonder if you just didn't get a GT35R.

I'll go measure....

Ok:

The Gt35 R wheel that I have here measures:

61.4172mm/82.0166mm

The P trim turbine that I have here measures:

64.2366mm/73.406mm

The GT35R turbine that I have here measures:

61.5442mm/67.818mm
