2.5L Duratec Turbo Swapped Mazda 3 Review - Easy To Build, Easy To Love!

My thoughts on a 2008 Mazda 3 with a 2.5L duratec motor and turbo swapped into it and paired to a 6 speed manual transmission from a Mazdaspeed 3!

[@cesarpalmos8235]

By the way, the Mazda 3 was a rebranded ford focus. The Mazda 6 is a rebranded Ford fusion. I myself have the 2011 ford fusion 2.5l manual transmission. The reason I bought the Fusion is because I love the Speed6 however I wanted the 2.5l and like the looks of the fusion better. My fusion is kind of rare being a manual. Fun fact, the transmission in the fusion is actually the same transmission used in the non turbo Mazda 6 manual. I actually plan on putting a turbo on 2.5l, swapping in the Speed6 transmission with the AWD rear end. Since it is a ford fusion, the Mazda speed awd system wil bolt onto my Fusion.

[@haydenw.1529]

I have a 2013 Ford Fusion with the 2.5l duratec engine and would love to turbo it so would this 2.5l be the same as the one that’s in my car cause there are different orientations of the 2.5l

[@alexanderdanielsson6049]

it is the same

[@eventhorizonperformance]

Congrats, you have the most reliable, but slowest Fusion model. As stated, the 2.5 is exactly the same and in the same orientation as swapped into the Mazda. You can turbo a Ford Fusion no problem, but you will probably have to fabricate your piping and manifolds as there isn't much of anything aftermarket to choose from off the shelf. The 2.5 is a slug in Fusion due to it's weight. In a Mazda 3 it's decently quick.

Im curious too. I wanna know if he has stock conmecting rods and how much boost

[@eventhorizonperformance]

@@i.t.s.t.h.e.c.a.l.z.o.n.e These motors can reliably hold 350-400hp /w associated torque if you have a good tune dialed in. They are built very tight from the factory, so beyond that the ring gaps can cause issues, which is why many 2.5 owners looking to make big power regap the rings.

[@monicanazario6832]

I need help my brother in law has the same make and model and he is upgrading his to a 2.5 turbo from a 2.3 turbo and he wants to run it only at 300hp even though it can go to 400 originally from the 2.3. But he just wants to know with the 2.5 turbo how many pounds of pressure torque does he need to apply on 3-11 Newton miller meter ? I need help big time I’m going nuts searched the entire internet and nada!! Please help!!

[@monicanazario6832]

He is doing the header swap from 2.3 to a 2.5 just the header and a bigger turbo. Everything else is original 2.3 parts! I need help!!❤

2.3 head

[@LifeOfTuners]

Probably 2.5 head as well

[@resignator]

@@LifeOfTuners 2.3 head bolts right on. Everything bolts right on...alt, water pump, sensors, etc. Same exact engine only one has been bored out.

[@eventhorizonperformance]

Everything from the 2.5 is used from head to bottom end for the swap. You have to install a 2.3 timing cover, crank pulley, use your Mazda harness and a few other odds and ends. 2.5 head flows more than a 2.3, no idea why you would get just the block, unless you are changing out the bottom end on a MS3. If you are doing the swap, no reason to take apart the engine. You can get the entire longblock for a few hundred dollars and just drop it in after prep.

[@jvogler_art4708]

How do you get a car like this to pass emissions is my only worry. Thinking of swapping a 2.5 into my 81’ foxbody (has a ford straight 6 with only like 100hp)

is it the ford 300? that thing is a beast if you rebuild it/upgrade it.

Don’t think so. Has to be 2.3 head from what I’ve read

2.0 and the 2.3 transmissions are exactly the same. You can even use your stock 2.0 flywheel and clutch.

[@elrusso22]

how many max rpm does it lift

[@eventhorizonperformance]

Stock redline on a 2.5 is ~6500, but you can rev them to about 7000 on the stock valvetrain. I would not go higher than that on a stock head. Most people just leave the stock rpm limit that was on their 2.0/2.3. These are pretty torquey engines with a lot of power under the curve, so you don't really need to rev them out like a smaller displacement motor, at least on stock cams.

[@uhmeizuhngralphf0549]

The need for speed

[@lspivey1207]

The 2.3 is built by Mazda not a Duratec.

[@eventhorizonperformance]

All Duratec motors were "designed" by Mazda. Ford acquired the rights to manufacture the engine for the Ford lineup, but it's the same engine that went in the Mazdas as well.

[@Mr19860823]

lost me at ford

[@sarahburnside4606]

It’s a Mazda designed and manufactured motor that ford slapped in everything, not the other way around

[@eventhorizonperformance]

All Duratec engines are Mazda designed. Ford bought the rights to manufacture the engine for the Ford Duratec lineup. The longblock for these engines are exactly the same between Mazda and Ford. You can swap one into another and drops right in with no modifications. You just have to dress the longblock with either for Ford or Mazda harness, depending on what car you have.

Can you mute that into an.nc Miata?
