2017 fa20 engine into 2013 car?

The crank angle sensor changed to a different type. The older ecu wouldn't be able to interpret the different signal output. The mounting plate has been changed too. However, that doesn't necessarily mean the old sensor hardware doesn't bolt up.

I think it is being explored as a replacement if the stock 2013-2016 motor blows up and you don't want/need a built engine.

I have no argument. I am saying that you have no argument contralateral to swapping in the new engine, or FI on it, or any number of undiscovered items. The changes made to the engine are also a known variable. I imagine the changes were more for reliability that just happen to yield a 5 hp potential.

Isn't potential incompatibilities and/or extra costs involved with swapping to '17 engine a "contralateral", as you used the word? I don't care what you imagine. I simply asked you to justify that decision with data. What are you going to gain with the swap?

And I am saying if the OP's motor lets go, what does he have to lose? He would get a newer engine with the latest angle cam adjustments etc. This whole thread is about an engine used for racing letting go.

P.S. You realize you can swap the harness too right?

There's no answer at the moment. Very much a first person to try it sort of thing. Could be simple if you have a donor motor to take sensors from, or may be too expensive if you end up needing the ecu and harness too. The improved internals would be more durable and possibly incrementally lower oil temps.

The point isn't to swap for mo powah and building, it's a replacement engine, op is unlikely to majorly modify the engine so getting a newer design is a reasonable idea.

But given the other parts about sensors and connectors changing got the 15-16 it won't be plug and play and there will likely be more trouble shooting than with a 13-14 engine.

The 2017 ecu/tune is supposed to be quite different, but it would be a good option if the 2013-16 systems would work fine with the newest version of the fa20.

I just did this. 2017 FA20 into a 2013 FRS. Is not a plug and play replacement...infact you have to do a lot of unplugging and swapping of parts to make it work. Basically the complete engine wire harness and the items listed below.




Crank reluctor wheel is different as well as the crank sensor and crank sensor mount which bolts in from behind the engine under the flywheel.




Pass side fuel rail is different and uses a different sensor


Coolant sensors are different

Ignition coils are different 2017 uses a 3 terminal connector 2013 uses a 2 terminal connector

Was it worth swapping to the newer engine?

It was for the owner of this car. He detonated his old engine...both crank case half’s had a few holes in them. Exhaust was full of coolant and metal chunks...did a real thorough job...pretty impressive actually

I did a few honda motor swaps back in the day, Honda made it so simple to swap motors, harness, mounting points, connectors all were "swapable" between cars and/or with little modification. Those where the good days, with no CAN system in the car, just swap and go!

Does anyone know how these differences compare to the 15-16 engine?

bump.. for what it's worth.. i had a similar experience with blowing a hole through my crankcase similar to above... I have a 2014 BRZ that was manufactured in 2013. I ended up going with a used 2015 moto and I ended up using the 2014 harness and the 2014 ECU since that ecu has my ecutek license flashed on it..... haven't started it up/tried turning it on; but all connectors/plugs plugged right in for whatever it's worth.
