Sigh, it looks like the map got dropped off when pte redid their website. I'm pretty sure I have a copy at home. If so, I'll put it up somewhere and post the link. Also, looking at all their listings, it seems they offer "real" GT turbos (as Two Lane puts it) with either regular or ball bearings.
Some GT turbo info

Here's the map for the GT61 compressor wheel: http://mysite.verizon.net/carl.ijames/SC61.pdf. I sure wish one of the Garret vendors would put up all the maps they have.

Thank you for posting the map.
Have a safe and enjoyable weekend.

Until having found the same consistent info from several different sources, it's of no use in my book.
Here's one of several, quoted below.
Also, do a Google on GT turbos by Garrett, in addition to the Garrett PDF catalog. Simplistically, the 2 major improvements in the GT-series are: 1.) Improved aerodynamics and 2.) the use of ball-bearings.
QUOTE==================================
Garrett basically has two lines of turbos. The older, out-dated T series turbos and the newer ball bearing GT series turbos.
T family has T22, T25, T3, T350, To4B, To4E, TS04, To4R ...These are very old, WWII generation turbos.
The newer line of GT turbos are ball bearing on journal and thrust bearing.
The turbine and compressor wheels are improved aerodynamically to flow more air.

Then, research the newest Garrett GT-R series.

Note the "Proprietary Notice" at the bottom of the compressor map for the SC61. Maybe this is why it was removed from the Precision web page.
I have heard that Garrett feels this information is proprietary and they do not want it released. Their web page does have compressor maps for different compressors, but they are overlayed with many different combinations and it is difficult to make any sense of the maps.
I appreciate the posting of this map.

I bought basically the same turbo you did. P trim turbine in a Precision .63 housing, GT67 compressor in a to4s (60-1) 4" inlet 2.5" outlet housing. I was surprised to see when it arrived that it is a small shaft turbo. I guess this is the new upper limit for compressor wheel size on a small shaft? I have to do some plumbing before I bolt it on. I'm moving my 3" maf to the uppipe so the 4" inlet will be unrestricted.
Bringing back an oldie!
The GT42 wheel is closer to 68mm than 67 (67.818). I think that the GT67 wheel is actually out of the TO4R (66.5mm). Anyone find a map for this wheel yet?
The GT61 compressor wheel is out of the GT35R turbo. You can get that map on www.turbobygarrett.com:)

The TO4r wheel is what PTE has been using in PT67's, are you sure this is a new wheel? I thought it had been around for a while now?
