There is a FA24 short block swap running in MN. Car is using FA20 heads and ECU. Made almost identical HP to a stock GR86 on the same dyno.

I believe the car was on track this weekend too.

Still i m not understanding how doable is this swap, fa24 short block into restyling fa20 with fa20 heads?
Did someone here figure out what s really needed?

Yes - I am sure he wants to do more testing before posting it all up. But, its a shop in MN.

My concerns would be valve clearance. Are the valves the same diameter and in the same position and angle on both motors? The piston crowns are different between the two motors. I could imagine the valves being larger and maybe further apart on the FA24.

Besides that, the larger bore sleeve might partially block the coolant jackets on the FA20 heads.

I came across some comments by Ronnie the other day about it, he said that you just gotta get creative and that he used FA20 heads. Can't find them now that I'm looking though.

The crank position sensor was asked about on their post but they were a big cagey and just said "they made it work". but it was done with a stock 2013 ECU so thats hopeful. We just have to figure out what they did.

That's why I didn't wanna say who it was, I'm guessing he is going to put something more formal together eventually on the process. But have seen pictures of them doing testing on clearances/etc for a while.

Probably just stuck the 13' sensor on with a modified mount with the 13' reluctor wheel.

I believe RS has for sure 3 cars running with FA24 swaps, and another shop(ASM) did one in WI.

I believe one of the FA24 cars will be at Gridlife this weekend running in club TR

Just remembered I posted this a while ago. Who’s got a guide? I want to pull the trigger on buying a GR86 engine. 😊

Same here - the price on used FA24s seem to have cooled off some and I'm interested in swapping to my '14.

I found this guide on NASIOC. It's specific to the FA24DIT, but there is useful information there.
https://docs.google.com/document/d/1...qrl9R-vJA/edit

I'm following this outfit in Japan. There are some more clues there.
https://docs.google.com/document/d/1...qrl9R-vJA/edit

Mostly I am looking for information on the FA24 cam sensors, crank position sensor, injectors, and a few other sensors (temp, pressure, etc.) and interfacing them to the FA20 ECU.
