I have done it but you need to change all timing sensors from 2.3 put on to 2.5 engine and i put my 2.3 intake on to 2.5 engine mine runs grate and still has 2.3 ecu
I replaced the engine with the second one and I have a problem to start it. At the beginning, the key on the panel appeared, I corrected it, the cables at the fuses were not pressed exactly, now the key has disappeared, but I still have a problem with starting the engine. I am not sure where to connect the thin cable to the starter with the white tip ,and I am not sure if it is connected to 12 V + plus or to (-) ground. I marked almost everything just like you, but not as accurately. And I don't know how to connect the cable that is attached to the radiator. I do not see the other side to connect, if you would like to take a picture of these cables that are pressed into the top of the radiator, I would be very grateful
The white connector goes to the starter solenoid. I'm not sure what "cable to the radiator" you are talking about. The only "cable" goes to the fan and there should be a corresponding connector for the cable on the fan.
I can tell from meeting you and your videos that your a very detailed oriented person so I'm sure mechanically you've done a good job on the engine swap. It looks like Kieth is willing to help out. His experience will be a great help. Let us know what he has to say. It would be interesting to hear his input. I like to hear about the scanners and how they're working out for you. I haven't pulled the trigger on a scanner yet. I want to get the right one and the Vantage seems like a good direction to go. (For us DIY'ers). Good luck with this issue.
wyattoneable first step is understanding what engine displacement really means. If we change the amount of air allowed into a cylinder and don't properly fuel for it .... well that creates a bad day . But I believe we have more to this one also.
wyattoneable remember that this has the original Ecm which still thinks it is a 2.3 , the intake manifold itself is designed to store x amount of volume also to feed the engine , we change that design and we have another strike against us
wyattoneable mass air flow sensor is possibly calibrated differently , and of course the base timing that I have some questions about. But I'm sure he will relay everything to everyone if we are able to work together to a resolution for all this
I wonder if the cam crank signal are the same pattern on the 2.3 and 2.5 . Could they have a slightly different pattern, spacing , and the 2.3 computer not like it . I think u had said still 2.3 computer . Seems u have done some good trouble shooting . Will be interesting to see what ends up being the actual issue . Hopefully someone will watch and know what it may be
Thanks. You raise a good point. The cam/crank correlations I've done and confirmed via known good waveforms match. So, the 2.5 as it is currently configured is generating all the right timing signals for the 2.3 PCM to work with. At least it seems that way right now!
That link might help you. The 2.3 and 2.5 engines are very similar, but very different at the same time. From a quick glance at that post, your ECU doesn't know how to run the 2.5 in its current configuration. It's a lot more work than just trading engines. I hope this helps
Thanks for the help. Actually the swap was a success and there wasn't any problem with the ECU and the 2.5. Cars running great with the new low mileage 2.5!
this might be the group I need to talk to. Someone trashed my old motor and i had to replace the 2.3l in my 2005 Mazda and I have reinstalled the new motor (used the same wiring harness that was on the original motor and everything is plugged in ) ,checked the grounds but when I install the battery i have NO Power, open the door no lights, nothing at the key or anything . When I took the old engine out it all worked but can't figure out what is going on now.. Can anyone help?
The group you need to talk to is at Mazda3Forums.com since that is an awesome collection of Mazda owners that have done just about everything on the 3. Your problem sounds like and electrical problem and I'd start by looking over the main fuses that supply power to the rest of the car. After you find the fuse/cable or connector that's preventing the current flow or power distribution you can get to work on the engine swap.
Unfortunately, the person that I bought the kit from does not seem to be selling them anymore on ebay. You should go to Mazda3Forums.com or FordFusionClub.com and search the engine swap threads for someone who might be selling them now. Below are links to what the kit looks like and the guy that used to make them. Maybe the guy on FordFusionClub is still making the kits. www.fordfusionclub.com/433-i4-engine-discussion/714833-2-3l-2-5l-engine-swap-using-2-5l-manifold-2-3l-throttle-body-2006-fusion.html OR www.fordfusionclub.com/433-i4-engine-discussion/716913-2-3l-tb-2-5l-intake-kit-now-out.html
@@matthewnivens7351 No, you don't have to change your intake camshaft. You DO have to change your intake camshaft timing wheel though. Nobody in their right mind would swap a high mileage camshaft into a low mileage replacement engine. Swap the timing wheel and done. The Fusion crankshaft pulley is different from the Mazda I do agree.
Been doing a swap 2.3 to 2.0 on a 2005 mazda 3 i used everything from the 2.3 engine. It cranks but no start so far. But Im not getting spark do i need to change the crankshaft pulley and the intake cam??
Jakob Wenzlick Sure but I've been thinking about that recently. The spacer kit is around $130. However, TB's from 2.5's are selling online for around $60-$75! I should have just bought a 2.5 TB in which case I would have saved money and had a proper TB too! Does that make sense?
No sir! The intake is fine and has been working fine for almost 10kmi. The problem was that the timing was off! Watch my other videos to see more. Thanks!
Also I kept some parts from the Mazda engine cause it if you kept the fusion parts as you can see they not the same as the Mazda so you actually have to keep some parts of the Mazda like the timing belt just contact me and I'll help you cause I had my car sitting in my mechanic shop for about 2 weeks
erik montoya Thanks Eric. The problem has been fixed. The timing was off. Car is running fine now. See my other videos for what happened and how I fixed it. Thanks!
miguel rivera Yes the timing was off all along. I paid someone to do it for me before I put the engine in and they did it wrong! The only thing that needed to be changed was the timing wheel on the intake cam. Yes the crankshaft pulley also. See my other videos on the swap and setting the timing. Thanks!
The one on left hand side in tappet cover it might look like a oil sensor but it part of the timing
I have done it but you need to change all timing sensors from 2.3 put on to 2.5 engine and i put my 2.3 intake on to 2.5 engine mine runs grate and still has 2.3 ecu

Somebody know where is that bap sensor? My Mazda 3 2.3 2005 show in the scanner P2228 and I don't know where is this sensor
You mean the MAP sensor? If that's what you mean then it's on the airbox tube that goes to the throttle body.

@@baxrok2. what was the answer?
@@KollynJ Timing was set incorrectly by a mechanic prior to installation into the car.
It's faster 2.3 or 2.5. What it's the diferents
might try taking it to a tuning/ performance shop and see what they can do
Thanks for the idea. However, look for my latest video to see what I ended up doing.

@@baxrok2. Thanks I appreciate it
Did you check the intake runner motor?
Yes. It was the timing. I made a video, or two, on how I figured it out and how I fixed it.
seems the 05 and older have problems with this swap
Is that a 2.3 valve cover? I had to use my 2.0 cover because of how the coild went.
Matthew Canfield No, that's the 2.5 valve cover and 2.5 coils.
Baxrok2 okay i wasnt sure i went with my old valve cover and 2.0 coil packs from what i researched the 2.5 coils wouldnt work.
Need to change the intake cam from your original engine. Also use your crank pulley off the original motor
No, ya dont. Not at all.
Baxrok2 04-05 Mazda 3 you do. 06 and up it’s a direct swap minus your sensors and crank pulley
@@matthewnivens7351 No, you don't have to change your intake camshaft. You DO have to change your intake camshaft timing wheel though.

Jakob Wenzlick Sure but I've been thinking about that recently. The spacer kit is around $130. However, TB's from 2.5's are selling online for around $60-$75! I should have just bought a 2.5 TB in which case I would have saved money and had a proper TB too! Does that make sense?
Baxrok2 yeah. I will look into it, are you talking about the tb from the Mazda 2.5's?
Yes, the Mazda 2.5's. The forum swappers report that a TB from a Speed 3/6 or CX7 turbo will also work. Up to 2012.
Sounds like a timing problem sound like the time is not a advancing
Yes, that is correct, it was indeed a timing problem. Thanks!
@Daniel Castaldo The problem was the timing. The person who set the timing for me did it wrong. Once I reset the timing myself it ran perfectly.
Mazda2005 2.3 swap for 2.0 2oo5 help .me it's no runing
Do you have fuel and spark? Also, Have you verified that the timing is correct by using the proper timing tools?
Baxrok2 I just put a motor in but having trouble I can’t find were the ground wires go I need help
The intake is to big!!!! Ik cause I did it to mine and the intake was to big that's why it ran ugly and wanted to shut down
No sir! The intake is fine and has been working fine for almost 10kmi. The problem was that the timing was off! Watch my other videos to see more. Thanks!
Valves cams sorry
ECM tuning makes every difference
Mass airflow sensor
Also I kept some parts from the Mazda engine cause it if you kept the fusion parts as you can see they not the same as the Mazda so you actually have to keep some parts of the Mazda like the timing belt just contact me and I'll help you cause I had my car sitting in my mechanic shop for about 2 weeks

erik montoya No worries. Thanks Erik!
erik montoya hey eric im looking to do a 2.5 swap on a 05 mazda 3. Can i keep the ford drive accesories and oil pan?
Chek your old motor yuo see cams are different
Timer is out, yea,
Definitely the ECU
No, it was the timing. No problems whatsoever running the stock ECU.
Timing is bad
miguel rivera Yes the timing was off all along. I paid someone to do it for me before I put the engine in and they did it wrong! The only thing that needed to be changed was the timing wheel on the intake cam. Yes the crankshaft pulley also. See my other videos on the swap and setting the timing. Thanks!
Vacuum leak!!
Nope. Timing was off! Not even a cam/crank correlation showed that the crankshaft was out of time by several degrees. Tricky stuff!
Destrperder,
Is there a way to rev the 2.5L to 8000 RPMs like a K Series?
Good news is the answer is yes, the bad news is that it requires aftermarket pistons
Iimp mode?
No. Timing was set incorrectly.
