Hi guys. I have a 156 2.4 of 136 CV. And I would like to change the turbo for the GT2256V, I think it is the one that carries the 156 175cv 20V. Does anybody know if it is possible to place the gt2256V cartridge in the original shell of the 136 hp? If it is plug and play or if it is necessary to machine the casing ?. Thank you.
