Not only the dual fuel injection system is good for cold starts but it also helps to reduce carbon build up on the intake valve.

[@SkinnierSteve]

I really hope they somehow find a way to keep UEL headers for the new STI's, because that sweet subie rumble is the best car sound to ever exist imo. There's no other sound like it. If the new ones don't have it, I'll stick to old ones.

[@angelpabon7580]

It's a very detailed video. Im a subaru fan with a 2013 wrx pumpkin limited edition. I like both the EJ and the FA, but another area that we need to look is the offset of the connecting rod. While the ones on the EJ are dead top center, the one in the FA sit in an angle. That puts pressure on a single area of the connecting rod. If you put both connecting rod next to each other, you can see the difference. Other than that everything else is great.

Damn the Ads are really going hard, 3 halfway in! I guess those FB prostesters found a new home.

It's like Mazda has done with their entire fleet in recent years. They all use the same 4 cyl engine, some are 2.0l others are 2.5l, they have different tunes + turbo according to the job they're supposed to do, and engine placement in the bay (some are facing sideways, others are forward) and that's how they get different power.

[@edugj23]

Most of nowadays engines are built this way, that's why an ECU remap is so effective, sometimes the only difference between two models is the electronic configuration.

[@messmeister92]

That’s what Subaru used to do. The problem is engines that are made to do everything usually don’t do any one thing particularly well. The EJ is a great example of that. There’s also a reason you don’t find aftermarket turbo kits for current Mazda engines, and there aren’t a lot of bolt ons for the current Miata: the engines aren’t made to handle that.

[@malevolution7041]

I'm excited to start working on these when they come to Aus!

[@mark11145]

Stoked about my next WRX with an FA engine. One mod I will have to do for sure is putting the unequal headers back on to get that same rumble my 2012 has.

I have a feeling deposits forming at the valves. Since there’s no fuel to clean the valves.

[@Hallowsaw]

Its really not hard to do a valve service every 50k miles.

[@kevingroover]

I suspect the new fa24 will be a dual injection system thus cleaning the back sides of the intake valves and cooling the air charge

[@kevingroover]

They've already got it in the fa20 naturally acid aspirated BRZ engines it would not be a challenge to Port over to the fa24

As hes talking about connecting rods being a point of failure, im reminded of my '14 wrx at the shop, wanting to hear back about a replacement block, due to a cracked connecting rod.

Doesn't direct injection without port injection also tend to mess up valve seats as well after prolonged use?

I recently picked up a 2023 wrx and couldn't be happier. The engine is more durable, stronger and most importantly, more powerful. Specially can handle a bit more tuning from stock then the ej.
