the other day i bought a greddy cast log mani, externally gated, and a tdo4h 15g turbo with downpipe for 150. turbo is in great shape. on friday night i finished installing my rhb5 ihi on an hf mani. its pulls alright, not the greatest setup in the world. what im wondering is how much smaller is the turbo i just bought than a tdo5 16g? and bigger than a tdo5 14b?
