well if you modify a different crossmember then yeah you dont need to modify the sump...like if you somehow get a 200b crossmember in there you can fit you can fit it with the stock sump and have heaps of room, but then you have to mod the control arms and stuff also

another way would be to just cut the whole centre section out adn weld another bit in lower...but you still have to avoid the draglink, if the engines that low that is

my sump thats got about 10-20mm extra clearance atleast than a stock one and it still only just clears the drag link
