2017 MT FA20 engine swap into 13 BRZ
Just picked up a 24k ODO 2017 engine out of a totaled BRZ. Reason being is I threw a rod in my 13 FA20 a few weekends ago and settled with swapping after I got a great deal on this engine.
I've read a few threads on here from years ago saying the 2017 engine wont swap to the 2013 because of harness compatibility. I would just like to know how true this is. I have a buddy with a 2017 FA20 in his 13 BRZ and claims its plug and play but a shop did it for him and I'm choosing to do the swap myself. Any info/tips would be great. |

not impossible, but a lot of small pain in the butt changes. the block is stronger though.

With that said...no one seems to know whether or not doing a complete transplant (17+ motor and 17+ ECU and harnesses) if that would just completely bypass all the trouble getting a 17+ motor to work in a 13-16 car. |

I think the easiest way to do this swap is to run the CPS out of the older car and use a degree wheel to index the old reluctor to the new engine and run that, or have a new one built. That is what solidsnake did to run his K24 on the stock BRZ ecu.

Is it safe to say dropping a 17+ motor into a 13-16 car is basically a poor man's engine swap?
Seems like the amount of trouble to get it to work is almost the same, except you don't have to do any custom fabrication to get it to fit. |
