The HKS GPROS is a great turbo upgrade for the nissan skyline R33 GTS25-T (RB25DET) and the R34 GT-T (RB25DET neo). This turbo gives a great compromise between response and outright power, 270rwkw to 300rwkw can be expected with this turbo, some have seen 300+rwkw. This turbo produces more power than the GT-RS but sacrifices a little bit of responce This is probably as big a turbo as you would want to go with a standard internal RB25DET.
