hi everyone i have a 1987 porsche 944 sohc 2.5 L. the tensioner broke thus leading the timing belt to jump off and i mess up some valves. i am planning on just changing the whole engine out. i found a guy selling an engine from a 1983 944. i was wondering if it would be a direct swap? i looked at the specs it seems that the older engine has about 10 less HP and is a little bit heavier compared to the 1987. it looks exactly the same why is it heavier and have less hp? i got the information from here
