Engine information

I have a 1974 911S with a 1970 2.2 T motor with Zenith carbs. After extensive work on the front suspension pan I was able to get the engine running reasonably and then something broke in the clutch assembly. I have a 1977 2.7 CIS engine that I bought from Oklahoma Foreign. My question is: Will the heat exchangers from the 2.2 fit on the 2.7? How can I find a diagram of the CIS system specifically the fuel filter and accumulator assemblies which were missing from the carburator motor and now must be reinstalled for the CIS. The engine's fuel lines were just cut off at the engine. Any help will be greatly appreciated. Thanks.

Yes your 2.2 heatexchangers will fit on your CIS 2,7 engine. You can find a god description of the fuel systems of different 911 models in the Haynes 911 workshop manual.
I would consider taking off the CIS system(sell it) and installing the zenits insted. It would give more power and a more responsive engine. You could then later consider fitting hotter cams. See The 911 performance handbook (Bruce Anderson) page 140. It has a description of an engine of that type. Even your T cams would de better than the CIS cams. Hovever, i dont konw if your stok Zenits can be ajusted to run on the 2.7 engine. Maybe someone has eksperinece with that.
