![]() From the reviews I've read (on the RA engine), although it's only a 5hp peak bump, it's much improved below 4k RPM's, where the STi is a bit flaccid, so the area under the curve has increased, which is more important than a peak number. Assuming this is the same tune and/or engine in the 2019 as the 2018 RA, it's actually a notable improvement to the STi.

Keep milking that EJ Subaru. Who gives a crap - most folks tune the car well past what any mildly hotter stock tune would provide, so it’s a net gain of exactly ZERO. Now if they beefed up a bunch of the internals, that something different, but I’m sure they didn’t... |

Most folks drive their car stock until the warranty period is up, or keep it stock for their ownership period. I'm not even sure most people on this forum start modding right away. As for gains with this updated EJ (again, assuming it's the RA engine) you get a better rotating assembly from the factory, as well as a better factory tune, while maintaining your warranty; does the EJ need to shuffle off to the retirement home? yes; but does the FA20/FA24 need to be rigorously tested prior to plunking it in the Subaru's top tier performance car? also yes. Subaru isn't likely to stuff an entirely new engine into a chassis that is at the end of it's life cycle and re-certify it, especially something that moves as few units as the STi does. |

![]() If you have driven the STI and the WRX you will understand how the dual direct injection system really punches torque in bottom range so the 5 more HP is just icing on a nice cake. Especially if they stay with 2.5 L in STI.

![]() This change is better than no change for those that still are interested in paying new car price for a piece of history in the EJ257. The change to 19" wheels (to now match the competition) really slowed the 2018 STI down so any additional power is welcome.

IF the '19s come with the RA engine, I see a surge of STI sales. |

![]() For an extra 5 hp? I can't see it. WRX/STI sales are pretty consistent so I would imagine it's enough to keep 2019's in line with 2018 sales but I wouldn't expect sales to increase because of such a minor change as there's still no Apple Carplay or Android Auto which stings more every year that it becomes standard in the rest of the industry and still has the same dated looks.

![]() I was talking about Subaru not being willing to re-certify for the rumored FA24 in a chassis that is at the end of it's life cycle.

![]() When it comes to the turbo EJ25, any power figure needs to be discussed in relation to octane level in the fuel.
Owners of the "RA" EJ257 will only get more power under the curve with 93 AKI gas in the tank; us here in Cali won't see **** as far as extra power below 4K. That is unless we get the engine carefully remapped for our fuel; which is something no owner should have or should need to do in a brand new $40K+ car. Now, if I were to buy a used STI, sure I'd play the game; but, a brand new STI? Heck no. Instead, give me Golf R, plays nice on Cali 91, give me CTR, plays nice on Cali 91, give me a FoRS, plays nice on Cali 91. In fact, give me virtually any new car without an EJ25 turbo under the hood and I guarantee it plays nice or, at least nicer, on Cali 91 ![]() |

Is all you see is the HP? Isn't the motor built with stronger internals? I wasn't saying if all it was was equal power that it will surge. I am saying if it IS the RA motor, it will. Quote:

That's how bad it is; that's what happens with a turbocharged, port fuel injected, short stroker. Even after tuning/remapping for Cali 91, the gap narrows a little bit, but it's still not as good as running 93 AKI. I can tell you that it's very obvious, even with my own WRX Wagon, when I run around half a tank of 100 AKI gas mixed in with Cali 91. The power delivery is so much crisper, it's really ![]() |

![]() But, I remember the Volvo S40 with a turbo I5, that had been around for a long while, and was still around when I purchased my 06 WRX Wagon. That Volvo turbo I5 is/was running SO MUCH better than even the EJ255 in my WRX; and, while Volvo was recommending premium fuel, that engine ran without a single hiccup on 87 AKI Cali gas. It's also an engine from the 90s, but being an inline engine, Volvo could get away with a long stroke, long rods and a tall engine deck. To this day, it's one of the smoothest and beefiest port fuel injected turbo engine I know. |

![]() LOL - you all must not live in CO. Every. And I mean every STi and WRX are modded up here.
Shoot my last last 3 turbo cars were well modded / tuned while still in temp tags. |

But, then again, if I have to spend $40K today, I don't want to have to remap my car. Remapping for extra power, for fun, is OK when it's optional and not strictly necessary. But, I strongly feel like every single STI with an EJ25 turbo must be re-tuned to run properly and safely on Cali 91. Same with 09+ WRX with VF52s. Nice; I probably paid something like $3.70 for 91 last week. It's probably surely higher now; I haven't checked yet. That being said, I don't drive much during weekdays; barely 12 miles a day. In any case, I'm very much looking forward to Subaru's next move regarding engines and such. My main evaluation criterion will be: does it run properly on weird-ass Cali 91 ? ![]() |
