It makes getting feedback on off-the-shelf turbos like this harder than you'd think it should be... That's not to say there aren't plenty of pioneers out there, but we could use more.

This But then again our crossover pipe is mostly to blame as most people are scared of welding or fabrication .

That Saied there has been people tunning the GT\GTX series on the 944 but no one i think has reported the 3071 most stuff is either 3076 or bigger . In discussions before everyone states it is to small for a 2.5l . Would love to see your findings .

GTX series is pretty good but getting a little dated. Xonarotor makes some very nice turbos but some fabrication is needed to bolt them on.
What ever you pick go with the Tial hot side casting - much nicer unit.

What changed between the GT and GTX turbos?

According to Google.
"Garrett’s GTX line is a modernized evolution of their legendary GT turbochargers. The GTX features forged billet compressor wheels and advanced aerodynamics, offering a 10-20% increase in flow and higher boost pressure ratios without adding turbo lag."

Seems a bit odd that there doesn't seem to be any 944 owner impressions on the earlier GT version.

I have mine custom made to my specs.
