Okay, okay. So I am replacing the clogged (and otherwise useless save for a paperweight) fuel injectors on my 1974 911 targa (no wisecracks please, I happen to like targas! :-P). So I order new injectors for the '74 and up 911's (part number 0 437 502 004), which are the same part #'s as the old injectors that I am replacing it. When I ordered the parts I ordered "all the o-rings and seals that I need", and I got the injectors, plus injector sleeves and 'o-rings' for said injector sleeves. Problem: my car did not come with injector sleeves, nor does it need o-rings for said sleeves. Instead it came with o-rings directly on the injector itself. (I have attached a jpeg, the new injector is in between the old ones, and the new o-rings are on top). The place I bought them from (Sorry Wayne, it was not with pelican) said that there is a possibility that my car was a 1973 1/2 and used the intermediate CIS system in use for 6 months prior to the introduction of the 1974 and on CIS systems, or that my car used the 2.4 instead of the 2.7 (used the last 2.4's before the engine was bumped up to 2.7). Now I have also attached a pic of the engine numbers, and I'm thinking that there is a possibility that that is a 2.4 instead of a 2.7 since it has the '901' . The questions that I have are two fold: 1) What engine do I have? Is it the 2.4 or 2.7? 2) What injectors should I use? Should I use the injectors for the 2.4 or the 2.7 with the early CIS system? Can I use the injectors that I have (for the '74 and up 2.7's, part 0 437 502 004) but just add the o-rings for the pre-1974 cars (since that is what the car came with--as far as I know at least). Any help would be greatly appreciated.
