    fuel systen on 911T cars

    I was looking at a 73 T recently and was surprised to find it was a MFI motor. I had thought Ts were all carburated but I was told they went to mfi for all 73s. Is that correct? What about 72 when the 2.4 L was introduced?

    72 and the first half of 1973 all 911s were carbureted. In the last half of 1973 the 911T started using CIS injection.

    The US/CDN spec '72T & early '73T were MFI, CIS from mid '73T.

    The ROW 911T was carbureted for all of '72 & '73

    D'oh. What is that called- brain fart? I meant to say MFI, but for some reason my mind was a minute behind my fingers and I typed carbureted since I had just read it. My bad.

    This is the correct answer.
