[s-cars] GT 2876 vs GT3071 vs GT 3076. Differences? Pro's? Con's? Opinions?

[Dave Forgie]

Last Sunday, during our Leavenworth Beer and Brat's run, I met Dan P. at
AMD.  Dan is running a GT 2876 and likes it.  I have done some poking
around and it seems like it might be a good upgrade from a KKK RS2 turbo
for a daily driver with no serious aspirations of going to the track,
etc.

Javad's comparison (2876 and 3071 but no 3076):
