Old comment but the reason is because they didnt reggaped the rings on the 2.5. I dont know anything about ring gaps but if im not mistaken, the 2.5 rings are too tight for boost thus creating scoring on the cylinder walls and ultimately destroying the ringlands, my friend has a 2.5 swap and repalced the rings and he made sure to reggap it for boost.
Ahhhhh right thanks for this, that's quite probable I'd assume, I also know the 2.5 don't have a forged crank, but I'm sure you wouldn't need a forged crank to go above 380whp
Been doing 2.5L swaps on 2.0L, 2.3L Mazda3's, Focus for years with lots of success. It takes a bit of fabrication to swap those particular engines to 2.5 because of the much larger ports in the heads vs the intake and exhaust manifolds, but it works great plus you add an instant 20hp or so. In my 25 years of racing experience, engine building as a certified technician in Canada, non-turbo builds like this are far more reliable as a daily driver and MUCH CHEAPER to build and maintain. It is true here in Canada as well, a 2.5L from a Ford Fusion is less than $700 from my local recycle yard. This is for 2.0, 2.3 and 2.5 swaps, non-turbo upgrade for those looking to get more power and maintain reliability of their daily grocery getter! Personally, I have a 2010 2.5L hatchback that I built about a year ago. I did it because everyone on internet chat groups, YT comments said it was a waste of time, a poor engine platform, go buy a Speed3 etc etc. That sounded a lot like a challenge to me!!! I started with a 2.5L Ford Fusion (130K) engine that I picked up at the local scrap yard for $600. I massaged the intake and exhaust ports, performed a balance shaft delete, installed a port matched custom 4-2-1 long tube header (1 5/8") that I had to fabricate, along with an anti-reversion chamber to take even more advantage of the massive torque these engines create. (Mazda guys we all know these items are not available for purchase so I was forced to fabricate them). Installed an injen SRAI, brand new MAF and wideband HEGO, a 2 1/2" custom catless exhaust, intake manifold from the Ford Fusion ended up working out far better than I imagined, eliminated the IMRC which was a GOOD thing in the end. I Installed a Speed3 hood and fabricated a true sealed ram air intake chamber that pretty much eliminates hot air from the engine while providing heaps of outside fresh air!. The ECM is tuned by Dynotronics (great tune but was hard to get them to respond to tickets for re-flashes once I went through the process the first two times, sadly). The key speed ingredient to my Naturally Aspirated 235hp 2.5L Mazda3 sleeper is higher flow injectors! We all know that high flow injectors aren't available for these engines, however, I found them and do have a limited supply. They make a HUGE difference in how the car pulls. It took me nearly three days of searching every corner of the internet knowing something would work! I never give up on anything in life and eventually was rewarded! These injectors are a MUST for ALL Mazda3 2.5L tunes. The injectors were the final addition to the swap/build, and I can say from experience that your 2.5L build will NEVER reach it's true potential without these higher flow injectors. As soon as they arrived I was like a kid at Christmas, went right out and installed them. I noticed a HUGE difference as soon as I pulled first gear after leaving the driveway. This car pulls the 1/4 mile in approx 14.5s and 0-60 is right around 6.0s (Dynotronics, mazdaedit software recorded and backed up with a drag race against a Scion FR-S and a Honda Accord V6 Coupe (std). Compare that to the stock 15.89 and 7.52 that I recorded at the track before this covid crap. Sorry for the long essay but just putting this out there that I can supply injectors and fabricate an identical custom header if anyone is interested. If you'd like proof of the build I can send pics and video as well. Thanks for taking time out of your day :) Never Lift!!!
For cost savings this is definitively the best option. For for performance i still think the 2.3 is better suited. Focus RS, Mustangs and Current Focus ST use the 2.3 L3 platform.
i actually have a 2010 2.5 manual hatch and honestly its abnormally fast for what it is. for you guys to understand, me and a civic si were neck and neck on a 20 roll race to 80 in fact i had a good jump because of the torque. keep in mind the civic si has 201 HP and My Specific car has 167 HP.
I have its brother, I have the 2010 Ford Fusion with the Duratec 2.5 (175hp) with the same Mazda 6 speed manual transmission. It is pretty decent for what it is.

Almost all of the major components, engine, transmission, suspension, exhaust, and even the door/fender panels are interchangeable. That said, the 2.3 turbo "Duratec" engine is from the same family as the 2.5 Duratec engine. The 2.5 is just a stroked and ported version of the 2.3. Almost ALL of the parts are interchangeable and bolt on to each other, except a few minor sensors and the throttle body. I plan on installing a Mazdaspeed 6 turbo, intercooler, intake manifold, exhaust, and a lot of other parts to make it a "Sleeper Build". I have already installed MS6 coil overs, brakes, engine mounts, and waiting on a MS6 short throw shifter at the moment to arrive. My Fusion is called "Project Confusion" because it will surprise people on how fast it will be when I'm done with it.
That's pretty awesome that I stumbled across this video. I've been seeing a lot of masa speed threes and sixes over the past few months come for sale or next to nothing. Might be worth investigating.
no joke thank u I'm in the states and bottom end is knocking now so this is way way cheaper than finding a good motor and doing a swap and upgrading the bottom end!!!
This is what I’m doing since I blew up my motor hopefully I’ll have it running again by September 💪 will for sure upload some videos or it when it’s done
So do you need to regap when swapping a 2.5 bottom block? I bought this 2.5 MS3 and the damn kid who sold me it doesn't have the original builders info. I don't know what he did to this thing (it drives fine though)
Nice video as always man! Kind of tempted to do this swap on mine when the motor gives. Also I want Brandon's headlights... and all of his bolt ons lol
I'm in the talks with my mechanic to probably start a project on a speed6 with cylinder 1 compression issues. He's selling the car dirt cheap. I hope my mechanic is ok with doing it with me, this sounds like the perfect solution. If it works out I'll document the process and post results here thanks for the informative video :)
Update.....you can drill and tap the oil filter housing and use a -4 1/8 npt fitting. And you could drill and tap the back of the block where the 2.5 mark is use -10an with 1/2 inch npt makes for a cleaner look then you need 36" oil feed line. But if you plan on building that 2.5 just use the 2.3 block 2.5 crank,rods,pistons and sleeve block with darton sleeves and bore out to 89mm go with speed performance 2.5 piston and rod combo and xspeedfab 2.5 tining chain kit
Not sure if you'll still read this BUT... If the external dimensions of the block are the same, would the sleeves be thinner on the 2.5 compared to the 2.3? I think it would be unless they put in different sleeves to keep them the same thickness. Asking this because if you build the motors internals the sleeves are the next thing you have to worry about
The record for bone stock 2.5 (long block, not a speed) is 454whp on pump gas. Not only is it cheaper, it takes just as much power. Going to a dyno later this month to attempt to break the record on a stock 2.5 in my n/a 2.5 mazda3 with a gt3076r. Not a lot of us out here trying to push the mazda3 2.5 platform but we exist ! The miata guys however have been doing a TON of stuff with the 2.5
@@ElSikario100 you can literally just speed parts. You can buy a manifold with an external wastegate, down pipe, turbo, intake for a mazdaspeed there and everything will bolt up and fit the exact same way

Your idea was super cool but i bought a built motor sp63 stage 3 engine , fully built on my mazdaspeed6 huge power now , my biggest issue is rust on the rear wheel wells
@LifeOfTuners just finished this week putting it in the car , with a new cpe top mount , corksport exhaust manifold, corksport catless down pipe ,cst6 turbo and magnaflow exhaust, to be honest it's a bit tough to work on to put everything back together with the dif in the way my poor hand are so cut up from the new heat sheilds . hopefully it will be worth it. just waiting now to get a appointment to have it tuned before i drive it . Also ifound a great deal on a mitsubishi evolution X MR in my area with everything already done for a great price perhaps a second toy
That is true, but the 2.5 crank can still hold plenty of power. I didn't say I'm the video, but the reason what makes the 2.3 weaker then we'd ideally hope is because it's stroke is quite long, compared to its bore. The 2.5 has an identical stroke with a wider bore, making it less willing to bend a rod
Too late I swapped my 2.3 MZR after 145,000 miles for a 60,000 mile unit June 19, 2020. I have a mild tune and I don't beat on her. I've had her brand new in 2011. Maybe next time.
You should do a video Like this for the speed protege. I have one and have come pretty close to maxing out the internals and info about swaps are pretty limited on the protege platform
Yes 2.5s are cheaper and provide a bit more torque. But also are weaker blocks. Cant hold as much power and torque as a 2.3 and ultimately are a bit of a cop out. There's a reason they're cheaper and it's not because it's a good idea.
Just to clarify, I know Speed bottom ends are only really good for 380-400 wheel out the box but built we all know they can handle 1000+. And considering 2.5s are still only good for about the same out the box, with a little more torque, what's the point? Fair enough putting a 2.5 in a regular 3/6 but they don't belong in speeds. They'll be just as problematic and finicky as 2.3's at 350+whp
Ehh in theory I guess yes, but it all depends, the 2.3s are so weak because their stroke is very long compared to the bore. A 2.5 has the same stroke but a wider bore, so the rods are less prone to bending
@@LifeOfTuners right so you confirmed what everyone already knows. 2.3 rods are weak. So replace them with something more heavy duty and the problem is solved. Chucking in a weaker block creates new problems without really fixing the 2.3's Achilles seen as 2.5's aren't very strong either.
Yeah, now think about how much that cost, you can't just chuck in new rods that easily lmao, no in not saying the 2.5 is the best, it's cheap, and it works, in some areas better, the 2.5s can hold 380whp, wouldn't call that weak
Hey man I have a Mazda 3 with a blown engine and I’m planning to put in a 3.0l Mazda Tribute engine do you think it will fit and if so what would I need to change?
I have a 2.5 2nd gen 6. Aftermarket parts are a headache to find and I have only found one company that will tune it- Dyno tonics. I just hit 200k, 100k of redline bouncing fun, and want to build a turbo MZR to replace mine.
I've got a mpv turbo that's lost compression on number 3, if I get a 2.5 can you come help me convert it 😆 🤣 awesome video too this is the info I've been looking for
I have a 2012 Mazda 6 2.5L, could I do the head swap from a speed into my car? As you talked about about, swapping the engine into a speed but what about swapping a head into a 2nd gen 6
I still think the 2.3 mzr is better if u blow up a speed 3 is cuz you are probably slapping parts on it without the knowledge this is a very hard platform to own especially since there's a lot of tuners dat don't touch these cars
Thanks for the video. I got 2005. Mazda 6 2.3. With a bad engine And i got a 2007 mazda6. 2.3. Do you know if i canswap that engine in my 2005. The only difference that i see is. The 2005. Use sparkplug wires and the 2007 use ignition coil.
I just so happened to pick up a K04 off a junkyard Speed3 recently. Pretty clean all around and with minimal shaft play. You think it's a good start for a 2.5 turbo build?
You are way better off just putting forged rods and pistons in a 2.3 then you can make any power you want im friends with the corksport guy's have a few videos on my tiktok of speed 3's make 922whp and 700 and they daily drive them thats the only weak part of the 2.3 if you wany to go over 400whp they are a blast to drive i own an 08 speed 3
Hey guys, needing to do an engine swap to my Speed6 because rods played a knock knock joke on me. Was thinking of just straight up getting a 2.5 from a Mazda 3 and putting it in my car for the time being, would I have to do anything to the transmission or would it bolt straight on? Would love some feedback
@@anthonymcnatt3799 well I just found a speed6 and I called evolutionary performance for pricing on the engines if they were to get me one and install it and a built engine would’ve been around 7-9k for the car and the engine and install and all that and a used engine would’ve been around 5-7k on a used engine I forgot the pricing but that is close what it would’ve costed for the car and engine and fluids
@@LifeOfTuners well it is informational and will help me on the next time I see a broken speed6 that needs an engine but idk I still took the L on the 3 times I found good speed6 but got sold
Definately not! People are making more power reliably with the 2.5 head and block. Also you'd need a whole new fuel system and sensors for the direct injection.
How about this engine swap for an early '05 Mazda 6 Sports Luxury 2.3L? Is it really as easy as just swapping it out? and are there any other more powerful engines available that could be swapped easily? Like the Models with the 3.0L v6, could that be swapped easily? Thanks
Yeah it'd be even easier to 2.5 swap a NA Mazda 6, as you'd keep the 2.5 head, I'm not sure about a V6 swap?, You could defo turbo the 2.5, there's a few people doing that now
If I buy a tribute and engine swap my mazdaspeed 3 with that exact motor on the tribute you telling me it would work? Cause I found one at 120k for 1200$

@@LifeOfTuners well I got it at an auction for $5.5k and there’s still some plastic wrapping in the interior back from 2008-9, I think I heard it was a commuter car so idk
Well. In Europe the ms3 and ms6 are more reliable because of the higher octane that is added to the fuel. I've seen ms3 with 280.000 km (about 175.000 miles) with a stock engine :)
Europe doesn't get higher octane petrol, it's just America and Europe use different rating systems, American 93 is about the same as 98 in Europe, though in New Zealand we get 100 octane. I've seen 2 with that higher KMs also
I have a 2010 Mazda 3 2.5 S GrandTouring , if the bottom is so good how can I get more power out of it instead of getting a mazdaspeed3 abd swapping out the bottom from my 2.5?

Right bro, just get a MazdaSpeed turbo setup, stock manifold, perhaps an aftermarket front mount with piping, an aftermarket bov, ms3 intake etc, but get a turbo that's for MazdaSpeed but slightly bigger, you can use a stock MazdaSpeed turbo, but it'll feel too small for the engine. You'll also need lines and fittings for oil feed and drain for the turbo, which means drilling into your oil pan.

But if you plan on building that 2.5 just use the 2.3 block 2.5 crank,rods,pistons and sleeve block with darton sleeves and bore out to 89mm go with speed performance 2.5 piston and rod combo and xspeedfab 2.5 tining chain kit
ohhhh good info
I just got into college so I just keep imagining the things I want to do to the speed 6 until I get enough money to actually do it
I think that's how a lot of people end up living ay aha
Bro same college is keeping me broke lmaooo
@@ryandol6341 it’s a struggle man 😂
Not sure if you'll still read this BUT... If the external dimensions of the block are the same, would the sleeves be thinner on the 2.5 compared to the 2.3? I think it would be unless they put in different sleeves to keep them the same thickness.
Asking this because if you build the motors internals the sleeves are the next thing you have to worry about
The 2.5 gets its bigger capacity from a larger bore, but honestly it's not going to give you trouble
The record for bone stock 2.5 (long block, not a speed) is 454whp on pump gas. Not only is it cheaper, it takes just as much power. Going to a dyno later this month to attempt to break the record on a stock 2.5 in my n/a 2.5 mazda3 with a gt3076r. Not a lot of us out here trying to push the mazda3 2.5 platform but we exist ! The miata guys however have been doing a TON of stuff with the 2.5
Yeah, it is a very underrated platform, even better without the speed head imo
How easy was it to turbo your n/a Mazda 3?
@@ElSikario100 you can literally just speed parts. You can buy a manifold with an external wastegate, down pipe, turbo, intake for a mazdaspeed there and everything will bolt up and fit the exact same way
@@alexsegura9012 *looks up N/A hatchbacks* 😂 did you swap in an LSD? I'm thinking about buying a project car soon for shits and giggles. Thanks for the info I'm gonna look into this now.
To get the lsd you have to do a speed 3 trans swap
In the video at the end is that 218 in NY by westpoint? If so I grew up there and drove that road often very very sketch in some spots. The other side of that little wall is a 500ft drop or so 😂 I had a Rx7 years ago and now a Speed3 Gen1 that's work in progress. Great video
Oh maybe, I don't know actually
You're better off swapping the whole L5, and converting to port injectiontion. Bigger turbo like a 30/76
Why
I would agree, the high pressure fuel system can cause internal damage if the injectors are clogged. Ask me how I know lol
I have an 2010 Escape basically the same engine too , finna mess with some people thinking it’s a pos
Frrrr it would
Your idea was super cool but i bought a built motor sp63 stage 3 engine , fully built on my mazdaspeed6 huge power now , my biggest issue is rust on the rear wheel wells
that sounds awesome, typical rust with mazdas
@LifeOfTuners just finished this week putting it in the car , with a new cpe top mount , corksport exhaust manifold, corksport catless down pipe ,cst6 turbo and magnaflow exhaust, to be honest it's a bit tough to work on to put everything back together with the dif in the way my poor hand are so cut up from the new heat sheilds . hopefully it will be worth it. just waiting now to get a appointment to have it tuned before i drive it . Also ifound a great deal on a mitsubishi evolution X MR in my area with everything already done for a great price perhaps a second toy
Started with a killahbuilt block. Redline is 10k. She is a highway girl.
10k 😳 SHEEEEEESHH
What springs?
Also you forgot to mention stock speed 2.3 crank is forged 2.5 crank is cast cranks are not interchangeable 2.3 is a better engine by design..
That is true, but the 2.5 crank can still hold plenty of power. I didn't say I'm the video, but the reason what makes the 2.3 weaker then we'd ideally hope is because it's stroke is quite long, compared to its bore. The 2.5 has an identical stroke with a wider bore, making it less willing to bend a rod
Too late I swapped my 2.3 MZR after 145,000 miles for a 60,000 mile unit June 19, 2020. I have a mild tune and I don't beat on her. I've had her brand new in 2011. Maybe next time.
Oh damn nice nice, they are great cars
Now I'm thinking about an NAT Mazda 5 lol
That would be so funny
Mhmm you do need to do a oil tap for turbo and a drain on the oils pan !!!
Yeah
I was going to mention Ford Fusion 2.5's will fit and allow for more power
Will I be able to swap a N/A Mazda 6 06 2.3 to a 2.5?
he’s definitely
You should do a video Like this for the speed protege. I have one and have come pretty close to maxing out the internals and info about swaps are pretty limited on the protege platform
I'll look into that, and find some info
I've seen a K swapped MSP, lol. I myself am trying to find a way to fit a Duratec in mind using the Ford Escort as a reference
Yes 2.5s are cheaper and provide a bit more torque. But also are weaker blocks. Cant hold as much power and torque as a 2.3 and ultimately are a bit of a cop out. There's a reason they're cheaper and it's not because it's a good idea.
Just to clarify, I know Speed bottom ends are only really good for 380-400 wheel out the box but built we all know they can handle 1000+. And considering 2.5s are still only good for about the same out the box, with a little more torque, what's the point? Fair enough putting a 2.5 in a regular 3/6 but they don't belong in speeds. They'll be just as problematic and finicky as 2.3's at 350+whp
Uhhh idk I'm not sure about that one
Ehh in theory I guess yes, but it all depends, the 2.3s are so weak because their stroke is very long compared to the bore. A 2.5 has the same stroke but a wider bore, so the rods are less prone to bending
@@LifeOfTuners right so you confirmed what everyone already knows. 2.3 rods are weak. So replace them with something more heavy duty and the problem is solved. Chucking in a weaker block creates new problems without really fixing the 2.3's Achilles seen as 2.5's aren't very strong either.
Yeah, now think about how much that cost, you can't just chuck in new rods that easily lmao, no in not saying the 2.5 is the best, it's cheap, and it works, in some areas better, the 2.5s can hold 380whp, wouldn't call that weak
Got to build the bottom end of the 2.5 or its melting a hole in a piston they are not made to see the Temps of a boosted app.
People run the time at 380whp
I wonder if you could put 2.4 SRT-4 engine in it? It's also non-interfierance motor.
I'd like to see someone stuff a built KL-DE in a Mazdaspeed 6
I added a 76mm turbo to my 2010 mazda 3 2.0L.

Hey man I have a Mazda 3 with a blown engine and I’m planning to put in a 3.0l Mazda Tribute engine do you think it will fit and if so what would I need to change?
I have indea actually sorry
I have a 2.5 2nd gen 6. Aftermarket parts are a headache to find and I have only found one company that will tune it- Dyno tonics. I just hit 200k, 100k of redline bouncing fun, and want to build a turbo MZR to replace mine.
Na right?
I've got a mpv turbo that's lost compression on number 3, if I get a 2.5 can you come help me convert it 😆 🤣 awesome video too this is the info I've been looking for
Glad you found it useful.
Ahaha I would have -32 faith in any engine I take any part in assembling 💀
Orrrr....
Get a Ford escape and put the speed 3 head on it
That wouldn't work with the stock ecu :(
I have a 2012 Mazda 6 2.5L, could I do the head swap from a speed into my car? As you talked about about, swapping the engine into a speed but what about swapping a head into a 2nd gen 6
I still think the 2.3 mzr is better if u blow up a speed 3 is cuz you are probably slapping parts on it without the knowledge this is a very hard platform to own especially since there's a lot of tuners dat don't touch these cars
Why is it better?
Mostly it's pushing the engine hard at lower revs and in too high of a gear.
Tuners tuning these would still tune a 2.5 bottom end. Has nothing to do with the software
Thanks for the video.
I got 2005. Mazda 6 2.3. With a bad engine
And i got a 2007 mazda6. 2.3.
Do you know if i canswap that engine in my 2005. The only difference that i see is. The 2005. Use sparkplug wires and the 2007 use ignition coil.
Yeah it can be done, it takes a little bit more work then putting another 2.3 in, but it is very achieveable
My 07 mazda 6i 2.3 sounds like a tractor at 4000 rpm uphill gave out. 😅 180000.00miles 👍 what do I put in it I'm on a budget and want to turbo my s#@!
2.5 turbo swap 🫡🫡🫡
I just so happened to pick up a K04 off a junkyard Speed3 recently. Pretty clean all around and with minimal shaft play. You think it's a good start for a 2.5 turbo build?
Oh yeah nice nice
You are way better off just putting forged rods and pistons in a 2.3 then you can make any power you want im friends with the corksport guy's have a few videos on my tiktok of speed 3's make 922whp and 700 and they daily drive them thats the only weak part of the 2.3 if you wany to go over 400whp they are a blast to drive i own an 08 speed 3
Nice
thank you
230k kms and still in incredible condition

Hey guys, needing to do an engine swap to my Speed6 because rods played a knock knock joke on me. Was thinking of just straight up getting a 2.5 from a Mazda 3 and putting it in my car for the time being, would I have to do anything to the transmission or would it bolt straight on? Would love some feedback
So what your saying is I can put a 2.5 duratec motor and then I have a turboed Mazda 3
I mean you'll need to.put a turbo on the 2.5
I was literally about to buy a speed6 with a broken engine and put a new stock engine in it XD
Buy a crate. The cost is worth it.
@@anthonymcnatt3799 well I just found a speed6 and I called evolutionary performance for pricing on the engines if they were to get me one and install it and a built engine would’ve been around 7-9k for the car and the engine and install and all that and a used engine would’ve been around 5-7k on a used engine I forgot the pricing but that is close what it would’ve costed for the car and engine and fluids
Oh maybe seeing the vid just in time??.
@@LifeOfTuners well it is informational and will help me on the next time I see a broken speed6 that needs an engine but idk I still took the L on the 3 times I found good speed6 but got sold
Oh yeah, well as long as it gets done is all that matters at the end of the night
I reckon one would also be able to swap these 2.3 heads into a 2.5 car too, right?
Definately not! People are making more power reliably with the 2.5 head and block.
Also you'd need a whole new fuel system and sensors for the direct injection.
You talk about extra horsepower? How about the transmission handling the extra horsepower?
The trans won't have any issues, damn they're even decently safe at 600-700whp
Transmission on this cars are bullet proof
was thinking about swapping this into an mx6 do u guys think it would work 🤨
Does this swap also work with NA mazda 6’s?
How about this engine swap for an early '05 Mazda 6 Sports Luxury 2.3L? Is it really as easy as just swapping it out? and are there any other more powerful engines available that could be swapped easily? Like the Models with the 3.0L v6, could that be swapped easily?
Thanks
Yeah it'd be even easier to 2.5 swap a NA Mazda 6, as you'd keep the 2.5 head, I'm not sure about a V6 swap?, You could defo turbo the 2.5, there's a few people doing that now
@@LifeOfTuners Alright thanks so much man, appreciate the help and fast reply :)

You can't 2.3 swap the 2.5, and tbf I don't think you'd want to
Hi where can I get Front and rear In and outer CV boots for a 6?

If I buy a tribute and engine swap my mazdaspeed 3 with that exact motor on the tribute you telling me it would work? Cause I found one at 120k for 1200$
Well obviously you need to swap over all the bolt ons, sensors, oil pan, head etc
i have a mazda 6 3.0 anything i could do to get more power?
it wouldn’t be worth the money, intake, full exhaust, tune
Is anything need to be done ecu wise after 2.5 block swap?
Just a tune, that's it, stock 2.3 ecu
No tune needed .... but it helps if you get one !!!
Should I sell my 2009 Mazdaspeed3? It’s completely stock except with a cold air intake. It’s got 147k miles but it runs really well but I’ve never had a Mazda so I’m sketchy about it
I mean at that milage it could blow up depending on how it's been treated its entire life
@@LifeOfTuners well I got it at an auction for $5.5k and there’s still some plastic wrapping in the interior back from 2008-9, I think I heard it was a commuter car so idk
Oh yeah that's pretty fair
Well. In Europe the ms3 and ms6 are more reliable because of the higher octane that is added to the fuel. I've seen ms3 with 280.000 km (about 175.000 miles) with a stock engine :)
Europe doesn't get higher octane petrol, it's just America and Europe use different rating systems, American 93 is about the same as 98 in Europe, though in New Zealand we get 100 octane.
I've seen 2 with that higher KMs also
Can I put a 2.5 in my 2005 automatic 2.3 mazda 3. -speed

I have a 2010 Mazda 3 2.5 S GrandTouring , if the bottom is so good how can I get more power out of it instead of getting a mazdaspeed3 abd swapping out the bottom from my 2.5?
I'm in your camp.
In my 25 years of racing experience, engine building as a certified technician in Canada, non-turbo builds like this are far more reliable as a daily driver and MUCH CHEAPER to build and maintain. It is true here in Canada as well, a 2.5L from a Ford Fusion is less than $700 from my local recycle yard.
This is for 2.5 swaps, non-turbo upgrade for those looking to get more power and maintain reliability of their daily grocery getter!
Personally, I also have a 2010 2.5L hatchback that I built about a year ago. I did it because everyone on internet chat groups, YT comments said it was a waste of time, a poor engine platform, go buy a Speed3 etc etc. That sounded a lot like a challenge to me!!! Basically it was a father/son build that he enjoys driving everyday. We did a bunch of body mods and installed Raceland suspension, looks as good as it drives.
I started with a 2.5L Ford Fusion (130K) engine that I picked up at the local scrap yard for $600 .... (nothing wrong with the original engine, just wanted to drive it while doing the engine build) I massaged the intake and exhaust ports, performed a balance shaft delete, installed a port matched custom 4-2-1 long tube header (1 5/8") that I had to fabricate, along with an anti-reversion chamber to take even more advantage of the massive torque these engines create. (Mazda guys we all know these items are not available for purchase so I was forced to fabricate them). I installed an injen SRAI, brand new MAF and wideband HEGO, a 2 1/2" custom catless exhaust, intake manifold from the Ford Fusion ended up working out far better than I imagined, eliminated the IMRC which was a GOOD thing in the end.
I Installed a Speed3 hood because I wanted to fabricate a true sealed ram air intake chamber to eliminate hot air from the engine while providing heaps of outside fresh air. Had the ECM tuned by Dynotronics (great tune but was hard to get them to respond to tickets for re-flashes once I went through the process the first two times, sadly).
The key speed ingredient to my Naturally Aspirated 235hp 2.5L Mazda3 sleeper is higher flow injectors! High flow injectors aren't available for these engines, however, I found them and do have a limited supply. They make a HUGE difference in how the car pulls. It took me nearly three days of searching every corner of the internet knowing something would work! I never give up on anything in life and eventually was rewarded! These injectors are a MUST for ALL Mazda3 2.5L tunes. The injectors were the final addition to the swap/build, and I can say from experience that your 2.5L build will NEVER reach it's true potential without these higher flow injectors. As soon as they arrived I was like a kid at Christmas, went right out and installed them. I noticed a HUGE difference as soon as I pulled first gear after leaving the driveway.
This car pulls the 1/4 mile in approx 14.5s and 0-60 is right around 6.0s (Dynotronics, mazdaedit software recorded and backed up with a drag race against a Scion FR-S and a Honda Accord V6 Coupe (std). Compare that to the stock 15.89 and 7.52 that I recorded at the track before this covid crap.
Sorry for the long essay but just putting this out there that I can supply injectors and fabricate an identical custom header if interested.
Right bro, just get a MazdaSpeed turbo setup, stock manifold, perhaps an aftermarket front mount with piping, an aftermarket bov, ms3 intake etc, but get a turbo that's for MazdaSpeed but slightly bigger, you can use a stock MazdaSpeed turbo, but it'll feel too small for the engine. You'll also need lines and fittings for oil feed and drain for the turbo, which means drilling into your oil pan. Oh and a tune of
