Default Physical size difference Between PT88 and 76gts (PT7675) Pics inside
I took some pictures comparing the Pt88 and the 76gts while i have both. Hopefully this will be helpful. Both turbo s have .96A/r exhaust housings.

that is not the turbo then, in all actuality that turbo should be done before 7K you have other issues.

What is the difference in weight? Do you know what the impeller sizes are? Do you want to take the covers off and take pictures?

The PTE H-series cover is the same on both the 76 and 88.

It looks (on the first pic) that on PT88 shaft is not further away from center of exhaust inlet than on 7675, can this be true?
