I don't have anything on a GT55. You'll need to call PTE or someone to find out the info on it (and the GT37R). Their new catalog has the GT-45R, GT-47 and GT-60 
, but no 55. Here's what I got on the three I mentioned.
GT-45R
Comp. wheel diameter: 94mm or 102mm
Comp. wheel Trim: 53, 56
Comp. A/R Ratio: 0.60
Ball bearing
Turbine wheel diameter: 82mm
Turbine wheel trim: 84
Turbine A/R: 1.15
GT-47
Comp. wheel diameter: 108mm, 117.5mm
Comp. wheel Trim: 56
Comp. A/R Ratio: 0.69
Ball bearing
Turbine wheel diameter: 93mm
Turbine wheel trim: 82
Turbine A/R: .96, 1.08
GT-60
Comp. wheel diameter: 141mm
Comp. wheel Trim: 56
