After owning both in various different stages of tune, I would say with a 40 - 150 race that a small single (575hp, 550lbft) ML auto with 3200 hi stall would be enough to get away (not by much) from a stock 2009/2010 GTR. This would be a dry and straight private road/track obviously. I think a manual you would struggle because of having to change gear. However if its stage one (just a map and decat pipe) then it could be running 570-580lbft from as low as 2750rpm and 600hp which is the killer if he's using Race auto mode! If its stage 4 + newer gearbox software which is very popular then ring Jamie and I'm sure he'll cane him for you
