fastfocus2005 I did this swap in my car and you do have to do the things as stated above....but I did find you only need to change the engine side of the harness for the 2.3 since it has IMTV AND IMRC(tumble flaps). The 2.0 only has IMRC so the 2.0 harness will technically work, but it only has the one connector for the IMRC. The 2.3 harness plugs into the vehicle harness without changes as well as the 2.3 PCM plugs into the original harness in the car so changing the harness that passes through the firewall is unnecessary. The only other thing you will have to do is have your keys reprogramed to the 2.3 PCM or your car will not start.

Fattie im planning on doing this swap. i can tell you for a fact that atleast engine wise ALL WIRING is the same. they are the same exact engines , with the exception the displacment is a little bigger , all connections are exaclty the same. take it from us guys here on the forum and not those guys at the shop. your better off taking it to someone who knows there shit or just do it yourself. that shop just trying to get more money out of you.

so to sum it all up unbolt your engine , bolt in new engine , shim engine mount , tune , done. someone please correct me if im wrong.

matmatician Actually, I take that back. Check this thread out! It looks like there may be some hope for the swap after all!! Had to get to FJ to find it though :P

matmatician Well, bad news :/ I got a call from the shop today and they had someone who knows foci really well, and he said that I would need all new harnesses and that they would have to redo all the wiring in the engine. Thats a little bit more expensive than I'd be willing to spend. Sooo... It looks like I'm gonna just stick with the 2.0 :'(

Rockstar92 Ohh alright I guess I will take my chances and get a tune from you after I do the swap. It'll be easier that way. Maybe by then sct will find a fix for it.

1turbofocus Yes on some there is a CEL for the ATX SCT says there working on it , it causes a CEL but doesnt do anything driveability or performance wise

Rockstar92 Hey Tom, yea I know that but I have also heard people complain about CEL coming on when they do a manual swap. Like they have a tune already for the new tranny but it still goes on so I just figured might be best to change to the manual ecu. But you know better than me could you fix that problem with a tune?
04-03-2012 11:45 AM
matmatician Glad you saw this Tom, i figured a tune woud be needed and word on the web is you're the guy for the job. Would that kind of tune be something you could do?
04-03-2012 11:34 AM
1turbofocus I cant think of a reason that you would have to change the wiring and ECU , I would just get a tune which can change the engine size in the tune and tune your new engine

ah sweet I am collecting money right now for the swap. I almost gave up on the 2.3 swap was just going to do a manual swap until you came along. That would be awesome let me know how it goes and what is needed.
