ENGINE SWAP


My first post: Hello everybody.
I have two nissan altimas 2.5 S and 2.5 SL, 2010 2.5 S, body is damage but engine and tranny are good, the other one is a 2012 2.5SL, good body but engine is damage, so could I swap the engine from the 2010 to the 2012? If yes, do I need to swap the computer, harness or something to make it work?
Thanks in advance

Are you driving both the 2.5S and the 2.5SL, or just the 2.5SL?

If you are driving both, I would highly recommend getting another used 2.5SL and do the engine swap from there. If you are ONLY driving the 2.5SL on a regular basis, then go ahead, because its the same components and engine as the 2.5S (if I am correct).

You should be able to assuming its the same generation L32 Altima. Seems the newer version L33 came out mid point 2012, so may not be as easy if its the newer model 2012 you have. Looking under the hood of both should tell you if they are the same or not.

Thanks very much. Finally I have an answer. I am going to keep just the 2012 2.5SL. I am going to party out the 2010. I already installed the engine and transmission on the 2012 2.5SL, love the way that car looks. Everything look like the same, all connected in same place. Now the problem is that I have not power inside the car, only have power on the brakes lights besides that is nothing working inside. Where could I start checking? I replaced the computer, the fuse box, etc and nothing. If I switch the computer, Do I have to use the key that came with that computer? Do I need to replace the start button?
Thanks again for your reply

Thanks very much. Happy to see another reply. I hope that they the same, I will look when I get back home later but I already installed the engine and transmission on the 2012 2.5SL, love the way that car looks. Everything look like the same, all connected in same place. Now the problem is that I have not power inside the car, only have power on the brakes lights, besides that, is nothing working inside. Where could I start checking? I replaced the computer, the fuse box, etc and nothing. If I switch the computer, Do I have to use the key that came with that computer, meaning 2010? Do I need to replace the start push button?
Thanks again for your reply

I looked on the door jam and found the 2010 was out on 02/10 and the 2012 was out on 10/11. Was that the info that I need to look out? and if yes, are they ok to do the swap?
Thanks again

Seems you already know they are the same. My guess is if you changed the ecu then you may be having problems with the key programming to it. I think the immobilizer kicks in if it does not recognize the key. If you still have the original 2012 one that your key was programmed for, you should try reinstalling it. Or maybe you could try removing the transponder chip from your 2010 key and put it in your 2012 key, and that way the 2010 ecu that you installed should see the proper signal so that it disarms the immobilizer.

I will try that, the start button is light up but in the on position, like the car is on. Is a main fuse that can power the inside of the car? or if I switch the chip on the key could be the problem for no power inside?
Thanks

The long block assembly of the engine is compatible from 2006-2013. You "may" have to swap over the intake manifold and/or exhaust manifold; you'll have to look them over an compare. You should be able to use the same ECM. Even if you don't, I believe the transponder chip memory is in the BCM during these years, not the ECM, but you could check with your Nissan dealer to be 100% sure. I remember Nissan starting to switch from the ECM to the BCM for key memory in the mid-2000's.

Thanks for the reply. I will call my nissan dealer to check on that info and post the answer.
