Here in Albuquerque, ambient air pressure here is about 12.1 PSI, so you start to want turbos that support higher pressure ratios than you would at sea level, and bigger cams to spool them. I went with the GT600Rs, which run out of steam between 2 and 2.5x ambient (so, between 12 and 17PSI). If I were to do it again, I'd probably go with GT675RS. It depends on your goal. If you want good spool, go with something smaller that maybe won't support as much boost at altitude, but the big power is going to be pretty much out of reach (also, we only get 91 octane here).
--------------------------------------- Your powers are useless! I'm wearing my tinfoil underwear! I will not shop at AMS. AMS steals designs from hardworking Z32 enthusiasts and screws them out of work in a tough economy. I am boycotting, how about you? |
