i read this on anouther forum (there is many ways of doing what you wont, the vg30 has a .63 turbine and the turbine wheel is also 8mm bigger than the stock ceramic which is the same size on both rb20 and rb25 motors. basic upgrade for a 2ltr is to use a 60 trim t3 core and machine the hsg to suit, for the 2.5ltr i use a t4e 50 trim comp wheel and 79 trim t3 shaft into the stock hsg.from there on in the sky is the limit, if you have a high threshold point using the vg30 unit is also due to having a carbon seal over dynamic,) Anyone else heard of this
