2.3 swap

[colinl]

first person I’ve seen mention this.. I was wondering the same thing a while ago when people started swapping in 2.3 out of the corsairs. I’d be curious if it was as simple as a manifold swap.

Also would be curious if the built motors from mountune would “bolt” in seeing as they make fully built motors for 2.0 from the ST focus as well as some performance items for stock 2.0 eco boosts. Maybe we’ll start seeing if the cams from them work and can be tuned with the 2.0 in the mavericks.

the best place to find this out would be to ask a tuner that specializes in ecoboost engine build/rebuild. tuneplus as one example. they would know whether a 2.3 transverse block from a Focus RS or older Corsair (they are now 2.0) is interchangeable with the 2.3 longitudinal block used in the ecoboost mustang and a bunch of body-on-frame trucks and suvs including the Bronco, Ranger and Explorer.

if I'm Ford I'm interested in using the same block for cost savings, but that's hardly a guarantee that you can use an Explorer or Mustang 2.3 shortblock in a Maverick.

pretty much what I was thinking. Can’t imagine a domestic company complicating things that much - especially with such similar engines just one slightly smaller in displacement.

But then again I’m not too worried as I don’t plan on diving too deep into the idea of motor swaps or built motors until someone figures out transmission upgrade or manual swaps. The factory 8spd auto seems like a grenade from what everyone is saying. Or maybe everyone is fearful of transmission issues that haven’t even happened yet.

Maybe an aftermarket company offering upgraded torque converter and valve body would make some engine builders more inclined to invest R&D into building the Maverick

I suspect the reports of their demise have been greatly exaggerated.

I agree with you 100%. Seeing the trucks been out since 2022 model year and doesn’t look like anyone has reported serious transmission issues it must be pretty solid.

Also I can’t imagine a manufacturer would use a transmission that is under specced for the torque output of a factory motor. I guess time will tell how long the guys who already have some high horsepower trucks transmissions will last

LOL, Until someone comes up with better CV joints, adding more power is a pretty good joke. If anything, the current halfshafts would appear to need less power that what they're shipping.

Not necessarily, when going with a larger turbo the low end trq moves up the rpm and many times doesn’t stress the power train as bad. Number two the drive shaft shop made new ones for the RS and ST in no time once someone broke them so this is a non issue.

First off I wouldn’t ask tune plus for water if I was in a desert. That dude is a liar.
One day it won’t work and your dumb if he can’t do it or can’t sell it, six months later when he can make money off it he pretends like he invented it. Not to mention he flat out lies about motors.
Been down that route never again. Hence how he got his tag a hole tuned.

as for the swap yes a 2.3 from the rs or mustang should work. It won’t be a simple manifold swap as we have headifolds as does the rs 2.3 and mustang. What you will need is the turbo setup because they are controlled differently. But in theory yes it should be a fairly simple swap. Then write the ecu starter map as one for a 2.3 mustang or rs. Both are basically the exact same with a slight machine work on the rs block.
Different turbos for different go levels between the two.
I have a complete long block and turbo for an RS in my garage as a backup. What you will need though is more fuel. The hpfp and injectors will need to be upgrade to get over 400whp on that setup. I was able to get 389whp with a heavy shot of meth and all the 93 it could give. But you can get full e85 with upgraded hpfp and injectors from Livernois.
So long of short yes it should be on the easier side. And yes use the 2.3 block and not the 2.0 like everyone seems to think is better it’s not. Many engine builders push the 2.9 block cause you can build them easy without having to machine a quality deck brace. So they push them as better when they are not. Cooling is far less on the 2.0 than the 2.3.

Maverick transmission is the 8F35, 35 meaning it is rated for 350nm torque. which I've always though is kinda strange given the stock engine is rated at 277lb-ft. that's over 350nm - about 378.

Ford has used the 8F57 in the Edge and Nautilus and they programmed it to use only 7 speeds. The 8F57 is rated at 570nm. presumably those internal parts are available and could be used but I agree, no one has needed to do that yet.

I thought the Maverick was also programmed to basically function as a 7 speed with the 4th gear often skipped... only in use when downshifting? sorry, I wish I had a source for the info, so I guess you can chalk my contribution up to rumor...

There are other ecoboost 4 cylinder specialists, I just picked one.

I don't know anything about them other than they post a bunch of engine builds on FB. If you've actually dealt with them certainly that experience matters a LOT more than me seeing crap on Facebook, lol.

cobb tuning was the first to offer a transmission tune for the Maverick about 2 years ago now, and my recollection is that they stated the Maverick nearly always chooses 7 gears and the 8th is almost unused in any factory map. and then in their transmission tune, it definitely only uses 7.

I can't recall which gear was unused, maybe you're right it is 4th, but for some reason I was thinking it was 2nd under very light throttle.

Found my reference to the 4th gear... Ford Shared the design of it's 10 speed.. In exchange... GM shared it's design for it's 9 speed.

Ford felt it could be improved by removing a gear, and elected to remove the 4th gear, turning the 9 into an 8... However, this resulted in the 2 to 3rd gear change feeling too close... so in most instances the 2nd gear is skipped and it behaves like a 7 speed. So we were both right! LOL

Here's the source:
https://advancedtransmission.com/the-new-ford-8f35-8-speed-transmission/

excerpt:
"THE 8F35
Ford decided that there was no real advantage to having nine speeds, and the extra gear added weight and cost that didn’t improve fuel economy. Essentially, Ford decided to remove the 4th gear, among other adjustments. These changes made the 2-3 shift step very small, and the transmission acts as a 7-speed under most driving conditions.
"
Of course, right after I found all of the above information, I also found the following MTC thread. Oh well.. should have searched MTC first... I more or less duplicated the information others shared previously.

I also found this article really enjoyable that explains the transmission warmer and the transmission cooler relationship...

Ya it wasn’t meant to say anything. It was just a mention. But I’d like people to know what they get everytime he’s brought up.
He has a cult like following but it’s never the same guys. You are signing his praises till you are not. Tons of unhappy customers and good customers from that guy.
Agreed to many good specialties out to deal with that guy.
I did Livernois but ford also offers the ecobeast 2.3, which is probably best bang for buck.

Do you have those part numbers for the tremor axles? I haven’t found a way to enter Tremor as a trim option when looking at Ford parts online stores, just xl, xlt, and lariat. And we’re talking front and rear?

Here are the fronts , not the insulator , that’s foam that goes in door jam for sound control on the lariats .
Those are full list prices .
my cost is 140 something and 180

You can have bespoke CV axels made for any application. It isn't that expensive, either. The issue is doing it at the multi-million unit scale that Ford needs. One-offs? All day long.

That isn't exactly how it works. Two years isn't a lot of time and we have had people with blown transmissions on the forum.

Also I can’t imagine a manufacturer would use a transmission that is under specced for the torque output of a factory motor.

Auto manufacturers do this all the time. It is notorious.
