RB25 block with an RB20 head and a Garrett GT3071R
So I have read online how terribly hard it would be to put this combination together but apparently someone did it. Not sure why but that is why I am here. Other than remarks that aren't helpful to the discussioin, could someone tell me what benefit this would have if any? If the changes were difficult I would assume that changing over to the 25 head would be a pain in the as* or not feasible at this point?
Thanks in advance.
