Question on a WRX FA20 swap into a FRS - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Stoll_It317 · 07-07-2017, 07:21 PM

I have yet to see or really hear about it but has anybody done a motor swap from the FA20 out of a WRX into the FRS or BRZ?? Same motor yet comes turbo from factory. So why not try and do this swap and save your N/A motor to be built for more power down the road? Essentially I would think it would work but haven't done the research myself. If anybody has any leads on the motor swap feel free to add on.

1) Cost
2) doesn't line up like you would think
3) doesn't make enough power to bother swap it

Its been done before but the person or shop that has done it doesn't want to release any information because they want to keep it proprietary. It is a lot of work figuring out from scratch from what I have seen but it is very do-able. It would not be worth it to keep your NA motor on the side to rebuild in this scenario.

but if you wanna do it and then actually share the information that would really help out the community.

Cheaper just to boost your engine.

Same block and that is about where the similarities end.
