I recently did a engine swap with a 1993 to a 1995 LT1 engine and was wondering if i could use the 1993 O2 sensors with the 1995 engine? or will i have to get new ones? i heard the 1993 O2 sensors werent heated and the 1995's were. Thanks!

 

correct you can use either 02 sensors, if you use heated you will have to wire power to them. i did the change to heated on mine.

 

i mean that i am using the 1995 engine and harness, etc. but i can use either heated or non heated sensors? what's the difference?

 

the heated ones dont foul so easy and put the computer into closed loop earlier. save gas and plugs if your rich at first startup. other than that they both use just one wire to provide the computer with info. are you using the 93 computer? you will have to use the 93 harness if you are.

 

No we transferred all the 95 harnesses and i mean ALL of them. So the heated O2 sensors are better?

 

Yes, if you can you should run heated O2's.

 

^^^ agree heated are better. you may need to have a 95 gage cluster. what transmission are you using?

 

We are using the 6 speed.

 

keep us up to date on how it goes.

 

alright will do. were still working on getting it to run. it was a big job! were going to try to get it started tomorrow will keep you guys up to date and ask questions if needed!
