if i ever need a turbo for the supra it will no question be a gtx, once you get upto a gt42 size the airflow gains equate to upto 150 hp more flow ? and thats on a turbo twice the capacity so a 3071gtx should potentially have an extra 75 hp of air flow, theoretically should make the same power at less boost so have more scope for future tuning, gtx ftw imo
