Two shops that I know with running / driving cars, both shops are owned by friends

RS Motors in MN has done a couple.
ASM in WI - I know he has one in his daily.

You may want to check out RS Motors on FB..... posted some teasers today

I saw that yesterday! Looks promising for those of us interested in this swap.

I saw the cam reluctor wheels they posted. Kinda what I have been thinking all along with just swapping the complete engine. The crank reluctor from the first gen engine I imagine should bolt on. What I am curious about is my understanding is that the 2nd gen has the same crank and cam signal type as the 17’+ first gens. So is the new cam wheels only needed for the 13’-16’ cars or not.

Edit: RS Motors did confirm the new cam reluctor wheels are only needed for 13-16’ cars.

Now if someone could kindly provide us with head CNC program to get to the right compression ratio/cyclinder volume using those FA20 heads :)

Or just use the entire FA24 :iono: I can’t imagine machining and rebuilding the heads and assembling them to the short block is that much cheaper. Also curious if they are using the FA20 timing cover and upper oil pan or the FA24’s.

Edit: RS is pretty responsive. I didn’t ask them for any more info since they did the work but it does appear with the FA24 short block they are using everything else from the FA20. I’d probably be best to ask them which route would be best to go with. I’d imagine for a DIY’er the complete engine would be easiest. The kit to do the complete engine is 700 bucks and they have 1st batch parts coming out.

$700 + FA24 engine ?

Probably factor in 2-300 bucks for incidentals on top of that too but basically that’s what it sounds like.

From the pictures on their FB for the FA24 shortblock swap it appears that the timing cover, upper oil pan & oil pan are used from the FA20 engine. They show a couple of pics of the FA24 block, no idea what, if anything is done with the heads to account for the 8.0mm bore difference (94.0mm to 86.0mm)...or if that is really an issue at all....

Looks like it will be at a simialr price point as the HKS FA20 2.1L Stroker kit

Still very, very interested....

I do believe that they have FA24 complete swaps completed so that cars can complete in ClubTR for Gridlife, in addition to FA24 short block with FA20 heads/etc.

My question would be, would either generation of Harrop bolt properly into place with this FA24 block / FA20 head combination?

Interesting, does that mean the car won't inherit the Gen2 oil pressure issues as they seem to be caused by the oil pan difference?

Possibly....

Does anyone have a picture of the actual cylinder heads from an FA24 from a BRZ/GR86?

I ask because I have an idea that has been brewing in my head....
FA24 block and cylinder heads with FA20 cam carriers, cams, front timing cover and oil pan (upper & lower).

IF, and I say IF, this all goes together this would be a drop in FA20 replacement. It obviously would need a tune to make it happy but based on parts diagrams only it looks feasible. I have the ability to try and assemble this...looks like about $5k in parts (FA24 short block + L & R FA24 cylinder heads. I have a donor FA20 to get the cams, carriers, front timing cover and oil pans from.

Anybody want to donate $ towards the parts, or donate an FA24, to see if this works? I'll put up $2500 of my own money....

I don't have that information, but you can get the '22 service manuals from my sigline and see if there's anything there that may help.

Appreciate it, I've got access to the entire Subaru Service Manuals as well.

Might be interesting as a proof of concept.
Using a non-OEM tune going forward as a marketing leader may be difficult.
It could fly in Florida. Will be hard to pass a smog test elsewhere.
Track only transported would likely work for the time being.

Does using 20 cams offer some sort of advantage over the 24's?

But there's only space for four.

@Kevin Vo tore down his GR86 you can ping him, I've seen a few more FA24D engine tear downs. Maybe you guys do a collab for YouTube, he needs content

Not so much the cams, but the cam phazers to keep the computer happy...

Hmm after watching that I'm even more convinced it'll work...it may also be possible to run the FA24 cams with the FA20 cam phazers....

There is a guy in the FT86Club Discord that has a 2017+ car running a FA24 longblock with few FA24 sensors and a few repinned wires. Are you sure they even need to be swapped?

For a 2013 - 2016 car, yes.

Sorry, I missed the part where that year range was mentioned.

I have a whole spare long block I got for free. 2013. I can get you whatever parts you need in it. Keep in mind, my understanding is that the cam trigger wheels may not bolt up to the fa24 cams. RS Motor’s is making different ones. Here is a picture they posted on FB. May be able to mod the stock ones to work but IDK.

I'm looking for 2022+ Cylinder heads, I've also got a 2013 long block. I've seen RS Motor's solution which is great, but I'm not so thrilled about the modification needed on the FA20 cylinder heads to make the FA24 work, that's why I want to try the FA24 short block & heads with the FA20 upper oil pan, timing cover cam carriers and camshafts....

They have a kit coming to use an fa24 long block. It’s 700. I was never really interested in trying to use the fa20 heads.
