| going to assume the two diff prices are because of the a/r size (and flange difference too) as for map comparison: [ http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT30/GT3071R.htm ] from what i recall on reading maps, they seem very similar but is it me or does the 3071 map look better? (again i haven't read compressor maps in years kinda sketchy on some things)
