may be stupid but did you switch plugs / coils from firing cylinders see if the packs could be bad? or take the coil out and off the plug go to turn the car on see if you get spark. again.. the whole wire harness could not have something that is now missing on this engine so its all guess work
The cam on the old 2.3 is 6 tooth which I was told is what it should be otherwise in the 2.5 as well.Quote:

Do you have the ability to monitor the cam and crank sensor to see if they drop out all.
If you haven't used a node light to confirm injectors are getting a signal I would start there. Maybe a shit coil in the injector. Otherwise trace the harness back to the pcm. Maybe a bent pin in a connector somewhere
Car is done and driving. Definitely worth it imo. Pulls hard, getting into triple digits faster in lower gears as it seems.
Had to reuse 2.3 intake manfiold, for whateverreason couldn't get the 2.5 intake manifold to work. Also had to swap oil sensor.
I'm also surprised by the MSDS header, its not loud at all, but then I noticed this with all the 2.5 gen 2 motors too. The 2.0 were obnoxiously loud and the 2.3 was too.
I have a 2010 Ford 2.5 swap in Gen1 mz3, runs good.. A bug or two to work out though. Still a newer motor with less k, for less then what I paid for my third 2.3. I'm not knocking the motor, I knew nothing about the said problems or rumours, I'm the first to admit it was my own fault my motors are done. With a header,cbe,cai, it changes the novelty of the car and rolling around at higher revs compared to when car was stock, I know I know these mods have no performance gains ;) just saying they were the cause of my particular story. Yea so I'm happy with the swap, I'm not sure exactly what all was done, and what still needs to be done, motors in, I can drive the 3 again so that's all that matters to me lol plus when I was mentioning costs.. My newer less km 2.5 also had a used $300 cbe for mz3 factored into the price and was still cheaper then any of my 2.3 replacement.
Glad it worked out for you.
Was there any issues swapping the crank pulley over? Also, the ac unit seems to be mounted differently on the 2.5 vs the 2.3. What's your input on that?
Thinking of tackling this soon. Anyone have any advice?Quote:

My timing was fixed in a few mins, and yes pulley swap.. No ac though. Be careful who you get to install it though.. Happy with the motor but discusted with some of the corners cut that I've fixed myself.
Can the AC be made to work though? That was one of the things that I've been looking the answer for.Quote:

figured i'd ask here since this thread keeps popping up. The ford fusion 2.5 drops right into our Gen 1's, so how much more difficult would it be to put in the fusion Ecoboost 2.0T. Is it just as complicated as putting mazdaspeed engine into a non speed? or would this be easier?
edit
obviously you'd need to get it custom tuned, i was more referring to whether you need all the other bits and bobs that are needed when doing the speed swap
Does anyone have the timing kit that I can borrow or buy off of?
just reviving an old thread. been reading about this engine swap for a while now and i'm happy to hear that the swaps have been working great for you guys! i will be doing this sometime in the future and just wanted to thank everyone for their contributions.
@a_ahmed: how's your swap now? all the issues solved? i know you're very happy with your new engine and i'm glad you like it!
@baymoe: how did your swap go? i know it was over a year ago since you last posted but just wanted to get an update. cheers!
It was great while it lasted, car was curb'd and it wasn't worth fixing so it's been ditched. Otherwise the 2.5 swap was worth it, i had the 6spd swapped in too. Probably my last post on here as i dont plan to get a mazda 3, i got a vette and 335i. I do need a winter beater again though lol... I miss the mz3, was the funnest winter car ever.
what happened to the car? i was actually going to research about how to swap in a newer transmission, preferably with the Fusion engine. would any other ATX transmission swap in with the Duratec 25? i really want to do the swap maybe sometime next year. thanks for replying so fast btw :)Quote:

I've been putting it off since I didn't have the garage space (single car) to take on such an ordeal. BUT I just finished the swap last night lol. Engine is fantastic, and had a noticeable improvement in torque.
If anyone has any question, I'll be glad to help as it's still fresh in my memory.
TIP
1) Disconnect the 3 main engine wiring harness from the box beside the battery tray and fuse panel. Leave the entire harness attached to the engine/transmission and remove it as a complete unit. The idiot in me decided it was a better idea to disconnect all the plugs with the engine still in the bay.
2) Find yourself a spring clip tool. I regret not buying it. https://www.amazon.ca/8milelake-Clam...lip+tool&psc=1
3) Buy the timing kit off me LOL.

Wow. Well done! 2010 2.5 is great! Nice swap.

WOW! that's amazing man! maybe if i take this on, i'll give you a ring haha. i'll be doing it myself as well. how much did you grab the 2010 2.5 for and where did you find it? i was looking into swapping in a ~2011 Duratec 25 non-hybrid. this is a 100% plan for the future and maybe even NEAR future lol. thank you for the detailed post! maybe if you come out for a meet i can check out the new engine :) cheers!
another thing is i'm looking to swap in a new transmission too and i have an atx. any thoughts?
i actually just looked up prices for the ~2010 2.5 non-skyactiv mazda engine and they're going for pretty good prices for a nice block. i think i'll be going this route after all. @baymoe we gotta connect and exchange info. you've inspired me to take this on!
I paid 650 for the engine and it was from a used car engine dealer in Brantford. If it helps with pricing yours out, mine had about 50K km on it. Came with intake manifold and throttle body (which i didn't use).Quote:

so from what i gather, i can swap in both engine + auto transmission from the ~2010 mazda3?Quote:

That's correct, ATX are usually easier to mate with a swapped engine. I will do some research and see if any newer ATX/MTX can be swapped into our cars. I know we have tons of info re: engine swaps but not a lot when it comes to transmission swaps. This thread is revived and fully loaded with information. Can't wait to see how many more of us are planning this! Thanks again for all your input @baymoe! Cheers!Quote:
