The part number is G445436-5 for the latest t28 hiflow compressor wheel.It has an inducer size of 48mm which is a touch larger than the wheel used in the s14's.You will need to get the comp housing and backplate machined to suit.This combination will give you the kick that the standard t25g lacks.These wheels can flow 35lbs and will give you over 200rwhp.There is a hiflow turbine wheel that is refered to as a t28 gtr wheel(not used on the gtr's),they are a bit pricey but allow the full potential of the comp wheel.Probably only worth doing if the turbine wheel/shaft was stuffed.Hope this helps.
