Well its a good idea but I have know of a person who did. He is situated in Penang but that was like 5 years ago. Lost his number. But then its possible if you change the whole engine .... Changing the block might bring problems to your other parts. There was a case that happen to my friend a few years back, he had an Altima 1995 and added a turbo on it. The engine could not sustain.
