2.5 Throttle body Install and review on 2.0 Skyactiv Engine
In this episode we'll be installing a 2.5 throttle body out of a 2014 Mazda 6 Skyactiv on my 2012 Mazda 3 with the 2.0 Skyactiv engine! Disclaimer this is only for the Skyactiv engines and not the MZR line. For MZR engines I'm not sure if the Throttle Bodies are interchangeable through out the difrent displacements (2.0, 2.3, 2.5).

The gentleman that ported the TB for my LS3 Vette explained that it’s not just diameter but how you machine the surfaces that can help the airflow. There was a lot of research and precision machining involved. His name was Pete from Vmaxx in FL I believe. I also ported by TB on my SRT4 and definitely helped. Nice vid!

[@DrivingProduction]

That's really interesting! Glad you shared that information! Thanks!

[@codysherman4030]

ya you use a specific grit sandpaper. I had access to a flow bench and was able to port and Polish my cylinder heads on my chevy 350. Used my CFM to get the right camshaft and carburetor and wow it rips now

[@defaultgenerico7749]

when changing the throttle body to a 2.5 definitely get a tune and a fitting intake, which you might wanna do too since a 2.0 intake is just as restrictive as the throttle body itself.

[@DrivingProduction]

Yeah will definitely get a tune soon

[@jonstechchannel]

You don’t want a 2.5 intake. Yes it will mount up, a 2.5 and a 2.0 intake will mount. But unless it it properly tuned, it will not run right due to the maf being different in the 2.5

[@Dyl_Cam]

@@jonstechchannel Could you not mount the old MAF on it?

What about with the throttle configuration? How avoid problems with this change?

[@Nini_V89]

I did the swap and it works wonders, my exhaust muffler sounds a little louder with more air coming in also. The response is noticeable also. I have an air intake with it, NGK iridium plugs and used premium fuel.

[@adibz959]

Its like drinking with bigger straw. Yes you get more volume of water, but slower rate and you need to suck harder. Small throttle body help to suck air much faster to the engine, which can give "induction" effect and also help fuel-air mixture to mix much better

[@stephentrash8579]

once he gets a tune, the bigger throttle body would be a lot better

[@davidjones-sd9ku]

Chat nonsense it's easier to suck water through a wider straw...

Looks so easy to install wow

[@DrivingProduction]

Yeah it's a really straightforward to install!

[@JohnBoulding]

Your plenum after the TB is what determines the air flow. All a larger TB does in this case is increase the mass of air coming in at the inlet. It does not add power and sometimes creates an air flooding point, which causes flat points in your power curve. Engineers designed everything to maximize power/economy already. Also "why has no one done this" question has been answered since guys have been using larger Tbs on cars for a long time. It looks cool but it doesn't really add power

[@2AMinLosAngeles]

ima be honest, i did this same mod a few months ago on my 2013 skyactiv 3 and felt absolutely no difference with the throttle body from a 2.5 skyactiv mazda 6. I would reccomend putting the money towards a basemap tune instead, much more tangible difference in power.

[@DrivingProduction]

I do agree that results from a tune would be definitely greater, but I think the combination of both would also gain better overall results. Thanks for sharing your input and experience on the mod! 👍

[@Dyl_Cam]

Yea I mean It be like that with a CAI/SRI as well, you gotta have a tune or it's sitting potential.

[@2AMinLosAngeles]

@@Dyl_Cam I mean at least with an intake you get better throttle response and intake sounds regardless of if you're tuned or not, I'm running an sri and axleback with a basemap tune and its definitely a noticeable difference.

[@2AMinLosAngeles]

@@Dyl_Cam fab9 tuning actually sells a real ported throttle for the 2.0 skyactiv in the nd Miata, but it's like $400 iirc

[@Dyl_Cam]

@@2AMinLosAngeles oh shit word, it's so funny how you have to get Miata ND parts for this car sometimes. Skyactiv market is horrible 😭

[@mellopena6770]

Can i do this with my Mazda 5? What would be the compatible TB?

[@DrivingProduction]

For the MZR engines I'm pretty sure the 2.5 already has the bigger TB, and the skyactiv parts aren't interchangeable.

[@robertneedham6335]

Very interesting. I was gonna fit an MST Performance Induction Kit for Mazda 3 Skyactive-G 2.0L, but is this worth doing instead, please? My mazda3 is a 2014 model (UK)

[@DrivingProduction]

For the 2.0 I found it's a great mod! As far as SRI goes I prefer CAI, but the MST one you mentioned does have a box to prevent hot air to get to it. If you're looking to get more induction noise for free I made an episode on it here: kzbin.info/www/bejne/Z165g2aNo7ihf8k

[@chrisbbb69]

I have never worked on a car i have worked with tools to install audio visual lol i dont know if id be able to oull this off doesnt look to difficult

[@DrivingProduction]

It's a pretty simple mod it only requires to remove a few bolts. It would be a great mod to start with!

[@ericrojas1476]

Any idea if this would work on a 2006 mazda3 2.3 na?

[@DrivingProduction]

This is for the 2.0 skyactiv engine, I'm not sure if there's any TB upgrade for the 2.3 MZR I think you already have the biggest factory one available, but it would definitely be something worth doing more research on!

[@5tun64]

I have thought about doing this, just wasnt sure if it would throw a code or not.

[@DrivingProduction]

Yeah it's a great mod, no codes at all it bolts right up!

[@5tun64]

I may try it

[@5tun64]

So i dropped the hammer and did this mod. I must say that it did improve the performance a bit along with the SRI

[@corbenmcgow4057]

Hey i know this is an old video but i was just wondering if this could be done on a 1.6 diesel and which throttle body would be best thanks man keep up the good videos

[@DrivingProduction]

I'm not sure about the diesel, if it's the skyactiv I think there's a 2.2 diesel but I'm not sure if they're compatible.

[@lucaspistorius6182]

And then port your head put higher compression pistons a set of cams a rev kit and itbs

[@bradleyward285]

Wth is a Rev kit haha. You mean a tune bc that's all you need to raise the Rev. Always start with a tune after doing exhaust and intake/ throttle body. With out the tune you will not get the benefits of adding everything

[@cameronforeman1043]

I feel like the ecu, certain sensors or something has to make a code pop up since you have that much more air entering the engine. I have a hard time believing you can just change that and get more high end horsepower and it just be a happy ending.

[@DrivingProduction]

Never got a code from it and the car drive great!

[@lucaspistorius6182]

Now make an adaptor bracket and put a bigger one than when your manifold can't flow enough get a custom ported mettle one

[@bradleyward285]

A tune is what he rlly needs

[@lucianminea]

It doesn't matter at all ! You can double the diameter of the air intake (if possible) and will still wouldn't matter. The air can be compressed a lot, and I mean A LOT ! It's not water, it's not fluid it's a gas. The air get sucked into the engine, not pushed, and with the throtle opened up at max, you can get more and more air as the RPM goes higher. Actually the air intake can accomodate 20 times more air than the engine will ever need. So it will never matter what size the air intake is for the airflow, and that it's physics 1 on 1 !

[@dylangauci3751]

Can you please share what cold air intake you have and where you got it?? I’m trying to change mine but some websites are expensive?

[@DrivingProduction]

I got it used off Facebook Marketplace, but this is the actual product number from AEM 21-765C. Unfortunately I don't think they still sell this intake system on there website. I did find this one: gbpperformance.ca/en/air-intake/27965-aem-cold-air-intake-system-mazda-3-20l-2014-2016.html?gclid=CjwKCAjwl6OiBhA2EiwAuUwWZT0q7eyGsfIO8x6BKEiBJolW2tVQ2wF2ICqdoZ7VGQakCZ23xHbVqBoC-fEQAvD_BwE

[@adenthomas4614]

i have a 2010 2.5l s mazda 3 is there any other throttle body that'll bolt up thats larger than the 2.5 oem throttle body that i can just go to the salvage yard and pick up?

[@DrivingProduction]

That's a great question, for the MZR engines in not sure if the speed throttle body is bigger than the 2.5 and if there's any benefits from using it. Maybe check on the forums it ight have the information you're looking for.

[@Counz223]

Any chance this would work on a 1.6L Skyactiv?

I'm not sure if it it would, I would think it bolts up but I can't confirm.

Thanks!

No this is only for the skyactiv engines, I'm not sure if the TB from the 2.5 MZR fits on the 2.0 MZR or if there's any benefit to it.

[@yvngbruhh]

Yes it fits all 2.0 skyactiv g engines

Will this work for the 2.0L 2008 Mazda 3?

[@DrivingProduction]

Unfortunately it's only for the skyactiv engines.

[@Slowestcarchannel]

any difference in 0-60 and where did u get the throttle body from?

[@DrivingProduction]

I haven't monitored the 0-60, but I don't think it would change it much if at all, this mod helped with throttle response and top end power. I got mine used on eBay. 👍

[@5tun64]

So , after a few weeks , how has it been ? Fuel mileage ? Power ?

[@DrivingProduction]

The car drives great! I would still recommend this mod, I personally didn't see any difference in gas mileage I do mostly highway though. Power wise the car still feels great and has more top end power.

[@awdmz3]

how fast did the ecu adjust to the change?

[@DrivingProduction]

I feel like the ECU adjust really by the time you get through a full tank of gas, but again that's just from what I've felt driving the car around

[@Dominik189]

This isn't an upgrade, it's a sidegrade and even with a tune I doubt this makes any real difference. If you want an actual difference involving Throttle bodies, swap from a single throttle body with a plenum after it to Individual Throttle Bodies with variable length velocity stacks in an intake box that's fed from a proper length cold air intake.

[@user-cw3xe5hj7f]

Found an oem 2.5 TB on eBay for $60 in great used shape. So I decided just to try it out, since it’s just $60 and it takes like 10 minutes to install. It’s definitely noticeably more responsive in the mid and high end range. Nothing crazy but the difference is there. I also slapped on a spacer after two weeks and the it helped a tiny bit in the low end. A few days later I grounded the TB with an 8 gauge wire to the negative battery post. Again felt a little more responsive all around. After those 3 super easy and inexpensive mods my 2014 Mazda 3 6 speed manual feels livelier. My car will never be “fast” but it’s a lot funner to drive and that’s what I wanted.

[@Dominik189]

@@user-cw3xe5hj7f ITB's would wake it up even more. Especially if you can do variable length velocity stack with a good intake box.

There a Mazda forum where someone actually logs their increased MAF after the upgrade

[@michaeldarmawan7307]

but how much horsepower does it increase?

[@elliotbrink6179]

Probably wouldn't do anything for the car unless tuned, if anything without a tune it could harm the engine

[@jonstechchannel]

Minimal. But, the benefit is in the pedal feel. It helps with throttle response. A tuned isn’t necessary, I ran without a tune with this upgrade and most of my bolt ones actually, for over 6-8 months before going up to Versatune’s shop to get tuned. Once tuned, I made more power due to all the mods combined, not specifically from any one mod.

[@emirkurtanovic6166]

What a can do with mazda 6 gh hatchback 88kw 120hp 2008-2012 5gears

[@DrivingProduction]

This mod is for the skyactiv engine, for the older MZR I'm not sure if there's a TB upgrade available

[@Dagowly83]

Oh dear. So the science of stack velocity goes right out the window... bigger TB doesn't necessarily mean more power. It means better initial response, but you're going to lose top end torque. You need to keep air entering the engine at speed, not slow it down.

[@brennanmessmer8983]

Ur definitely right but gas engines are basically a pump and the skyactive intake manifold has a large chamber built in to it so i would assume that the larger throttle body would allow more air to enter the chamber and the build some pressure going throw the inatke tubes I definitely could be wrong bc air velocity and clean intake flow in a na engine do create more power

[@andikappradana]

Does it affect fuel consumption?

[@DrivingProduction]

I personally didn't really see any difference in fuel economy

[@Chillnel]

the intake ports are smaller so not really much point really

[@dylanpurdom3466]

Wouldn't this lean it out?

[@DrivingProduction]

The stock ECU can adjust itself to a certain degree without being tune, I do monitor my AFR's with my headunit and they are still on par with the stock figures. To really take full advantage of this it would be best to get a tune.

I love how confident he is but wrong in so many ways. you are messing with fuel maps. the proper method would be to upgrade the fuel injectors, fuel pump, as well as retuning af ratio

[@razzle1245]

Why would you upgrade the injectors and fuel pump when they are probably still running at stock duty cycle. You only need to if your increasing a huge amount of power. On a civic r18 comes with a stock si fuel pump. Can support up to 300hp with a turbo. A tune with this I do agree.

@@codysherman4030 lol I agree that messing with fuel maps with no adjustment isn't the best. I'm a diesel tech. My 18' Civic sport hatch has a PRL CAI with a race MAF and a catback. I got a ktuner to make adjustments for the bigger intake size and the sensor to read those differences. If that answers your question. but there's no need to replace injectors, etc. only to adjust the parameters to add more demand for fuel according to the extra air. If you added a turbo and u max out the fuel system then yes. a higher demand for fuel is needed.
