80LS1T Posted September 14, 2002 Share Posted September 14, 2002 Ok, I know that the 93 LT1's did not have the reprogrammable computers and that they were Speed Density systems but what else is different? The reason I am asking is because I see all these parts for the 94-97's and not too many for the 93's...and guess what? I have a 93'! I was wondering if things like the cam and throttle bodys were the same or not? Can someone please give me some guidence??? Thanks a lot!

Guest LT-1 350Z Posted September 15, 2002 Share Posted September 15, 2002 92-93 and 94-97 intake & fuel rail diferent but it work if you have both from the same year. 92-93trouttle body diferent in the accelator cable and the transmission kick down cable {if you go stick don't worry} 92-94cam,distributor,timing cover,timing chain .diferent because new design in the optic spark{distributor}if you buy new cam just need to cut the pin on the cam like 1/4 inch and it fit perfect.] block is the same so are the heads 95-97piston and rod just ligther i also have a 93 and i like it better i think is stronger but that just my opinion Quote Link to comment Share on other sites More sharing options...
80LS1T Posted September 15, 2002 Author Share Posted September 15, 2002 Now about that Opti-Spark, where can I get an upgraded one? I have the old one on my 93'(non-vented). Where can I get one at a decent price??? Thanks a lot! Quote Link to comment Share on other sites More sharing options...
80LS1T Posted September 17, 2002 Author Share Posted September 17, 2002 Heres another question...Can I swap a 93' ECM for a 94'ECM? I know that the 94-97 has a reprogrammble chip but is that the only difference? Thanks a lot! Quote Link to comment Share on other sites More sharing options...
Guest LT-1 350Z Posted September 17, 2002 Share Posted September 17, 2002 if you are going to swap ecu just get the newer ecu and a air flow meter with matching harness.to swap to a new optic spark you the newer timing cover,timing chain ,the little cam pin.then it will fit.you can run the newer ecu on the 93 lt1 just remenber that the 93 has smaller fuel injector. my friend just used the new dit cap and rotor from a 95 in his 93 z28 Quote Link to comment Share on other sites More sharing options...
80LS1T Posted September 18, 2002 Author Share Posted September 18, 2002 So I cant just put in a 94' ECM and run it? What harness are you talking about? Not the whole engine harness, right? Thanks Quote Link to comment Share on other sites More sharing options...
