Jared the fusion Posted July 20, 2020 Share Posted July 20, 2020 Engine swap Curious questions Ford Fusion hybrid came with the 2.0 Atkinson engine that only produces 70hp and an electric engine with 118hp well a total of 188 hp isn’t horrible but what if you could swap the 2.0 Atkinson engine for the 2.0 eco boost engine. That comes with 240hp then you’d combine a 118hp electric engine making the engine near 360 hp with tones of torque from the get up and go from the electric engine that would be a cool setup and beat most cars especially if you did away with the stock turbo With The bell housing looking and appearing to match how hard of a swap would this be any insight? ps this my fusion 0 Quote Link to comment Share on other sites More sharing options...
bbf2530 Posted July 20, 2020 Share Posted July 20, 2020 (edited) Hi Jared. Welcome to the Ford Fusion Forum. Several things to discuss here. First...You do not mention your model year, so I am using the specs from a 2017 Fusion Hybrid as an example: Next...Unfortunately, the horsepower math does not work the way you are assuming. The 2.0L Atkinson engine output is 141HP/129 lb-ft torque (not 70 HP). The synchronous AC motor output is 118HP/177 lb-ft torque. Next...You do not just add the two horsepower output figures (141+118) together for a total horsepower output of 259HP. It does not work that way. Therefore, the combined/total output works out to 188HP. And correspondingly, the combined hp rating of a 2.L EcoBoost and the synchronous electric engine would be nowhere near "360 hp". Some basic math would place it well under 300HP (even if you could make it work...see below). Finally: Attempting to transplant a 2.0 EcoBoost would be extremely difficult to accomplish. Complete different engines (obviously), transmissions (obviously), engine management systems (obviously), etc etc. Certainly not worth the time, money or effort. Good luck with whatever you decide to do. Edited July 20, 2020 by bbf2530 1 Quote Link to comment Share on other sites More sharing options...
Jared the fusion Posted July 20, 2020 Author Share Posted July 20, 2020 @bbf2530 That makes sense I wasn’t totally sure ab how the hp calculations work, but still assuming that the turbo on the eco boost engine does add ab an extra 100hp over on the given Atkinson 2.0 would still give the car that little additive hp the car I’m focusing on is a 2013 Ford Fusion energi, running the 2.0 hybrid setup ford made the 1st gen 2.0 eco boost that are pretty similar to the same 2.0 in the hybrids without the same exhaust manifold and turbo I’m pretty sure the 1st gen 2.0 eco boost would be able to properly hook up to the cvt transmission that’s on the hybrid however It would definitely need to be tuned to be able to run correctly I believe wires would all hook up as well, (assuming ford used same plugs, if not would need to have to modify wiring harness) my question here is what are some unseen problems that I may be overlooking in this swap? If this project wouldn’t be worth it is there any suggestion on adding more hp to a hybrid Atkinson 2.0. ? 0 Quote Link to comment Share on other sites More sharing options...

If this project wouldn’t be worth it is there any suggestion on adding more hp to a hybrid Atkinson 2.0. ? Hi Jared. No. It is not a similar engine "...without the same exhaust manifold and turbos." And the CVT transmission is not compatible. The very short answer is no. This is not a project that would be easy or worth it. Not by any stretch of the imagination. It is essentially not doable, in real life terms. The Atkinson-cycle engine is specifically designed to maximize efficiency while sacrificing power to do so. The simple answer is if you want horsepower, a Fusion Energi/hybrid with an Atkinson-cycle engine is not the car to buy. There is nothing you can do to realistically improve power. No, tunes, cat-back exhausts, "cold air intakes", etc, etc. are going to help. If you want more power, the best thing you can do is sell the Energi and buy an EcoBoost Fusion. I realize that is not the answer you were hoping for, but it is the situation. If any of our members here have other information, I am sure they will jump in. If you do some basic Googling of the Atkinson-cycle engine, CVT transmissions, the 2.0L EcoBoost engines and their transmissions, you will better understand why this is a non-starter. Good luck with whatever you decide to do. Edited July 20, 2020 by bbf2530 0 Quote Link to comment Share on other sites More sharing options...
Jared the fusion Posted July 21, 2020 Author Share Posted July 21, 2020 @bbf2530 Haha thanks for the answer man!, and yeah I know the Atkinson engine isn’t designed for power, ? I wish they made a cam that would keep the valve closed so I could boost it a bit plan on hopefully doing a Tesla swap in the next few months so I’ll keep you all updated ? 0 Quote Link to comment Share on other sites More sharing options...
