Good call. Probably lighter bumper beams at both ends.

I believe they advertised as 200hp and 100hp/liter because it was 200 metric (ps) horsepower.

IMO the tiny difference is probably fuel related, and if you happened to add in some 100Ron fuel in the US model it might very well make 232hp

It was 197hp in all markets yes, but I think we all just subconsciously rounded up because 200hp was low enough.

Pre-release it was 197, but when it came to market in the U.S. it was definitely rated at 200hp here.

I'd be very interested in learning if this powertrain would be an easy swap into gen 1. I'm pretty sure, a couple of years down the line, someone will do it!

Many of these things are going to go to the junk yard because of accidents, so I'm sure someone will try eventually.

So weird.

I'd do it. Might be a good refresh if one of our engines decide to pull a fast one. Then again, I'm not wishing that future 2022+ owners get rear ended or drift into a pole, u know, stuff like that.

We know it's going to happen though. I'm suspecting this might actually be an expensive swap.

Swapping a 17 engine in a 13 is already not trivial, the 2.4 swap will probably be more involved still. I’m thinking ECU mostly, not many modern cars tolerate having a foreign Ecu very well, it needs to play well with the other computers. Might be easier to swap the bottom end if the heads swap over.

Considering that the FA24D has a larger bore (86mm to 94mm) for the same stroke (86 mm), I don't see how the heads can be swapped. Had they increased the stroke while maintaining the bore, might have been possible.

Wow. Yea. My brain was off apparently.

chipmunk · 04-19-2021, 08:04 AM

I was thinking the whole powertrain & drivetrain, including electricals. If all the mounts are same, of can be easily modified using adapters, I don't see why not

Yeah, I also had that wishful thinking line but Subaru's design will not allow us to go K24 block/K20 head route like Honda fans can.
