I though I would like it, but, I hated my 2015 STI, it just did not inspire me, even after some parts and tuning to get about 220 kwatw from it (only tuned up enough to not worry the glass ringlands), stock it made 145 kwatw on the Pulse dyno

I know no one who made over 250 kwatw reliability from one with a stock engine

I fell for the WRC fan boy marketing 

I was comfortable though, and cabin noise was minimal, so it technically was a OK daily, fuel consumption wasn't good for a true daily if that's a thing you look at though

2015+ FA20DIT CVT WRX better than all the above in the real world, and faster point to point on the street.

How was the cvt with cruise control?

Have found some wring themselves when going uphill. Take cruise off  and can maintain a much lower rpm by yourself for the same climb.

That's a shame.

The new sti are a gorgeous looking car.

Shame amd surprising they cant cope with even 250 on stock internals.

Haven't had the chance to drive long term, let alone own, but I found them OK in the stints I drove used ones when getting them ready for sale.

The STI in particular still had an EJ engine in it. It pretty much never had the ability to take big power. The entire block flexes easily and is not conducive to a long and healthy life with big power. The factory top-mount intercooler heat soaks very easily. The factory cast pistons put the compression ring very high up making it very vulnerable to knock in order to reduce crevice volume for emissions. Considering how weak the block is the 2.5L EJ257 used in the US is basically not designed to ever be stroked as the rod ratio is already on the low side. Normally not a problem, plenty of Honda engines run pretty extreme rod ratios but an EJ block is a delicate thing. The S209 in the US made 340 hp using an HKS GTIII-RS turbo and that is probably the absolute limit of what Subaru/STI powertrain engineers were comfortable with warrantying.

Can't say I've noticed a problem and does its thing nicely, but I can't remember being on cruise control on a really steep hill either as I'd be manual anyway.

People are making well over that on stock internals now, e85 does wonders

In the end when I looked at it I saw a Kia

I prefer the look of the older bug eye style of wrx

E85 is a PITA for a daily 

Lots of coin for fair-weather gain

I've ummed and arred over E85 alot, but due to it being logically hard to find it isn't worth the outlay for me

E85 is great for race cars or strictly low range weekenders, but for me, who calls a 400km a short drive, it ain't worth it for 2 or 3 trips to the drags a year

And there's no way in hell I'm carrying around jerry cans going for a cruise

That's why flex setup - best of both worlds. Have the advantage of E85 for your higher power performance scenarios and the convenience of just putting in 98 for normal use. No switching maps or draining the tank, so I definitely think it's worth it.

With an EJ25? The limit for ringlands I thought was due to combustion chamber pressures. While any one knock event can instantly kill the pistons at 250 kW to the wheels or so my understanding was even normal combustion could still damage the piston ringlands. Then from there the next thing to break would be conrods.

I’ve seen almost 300 with e85 in stock block

Stock block or stock bottom-end? I can believe stock block. The question is also how long you can make that power for. Subaru has killed 100% stock STIs under warranty by shipping poor tunes.

That's where the FA20 shines. At 10.6:1 compression running up to 1.6bar boost stock I've seen in the 6s for L/100km and up to 800km from a tank ! - it's insane how good the fuel economy is.

Granted the missus generally drives it being a bit of a lead foot and I still notice she's generally around 9 - 10ish L/100km.

The FA has a ton of technologies in it that make it halfway acceptable for fuel economy compared to the positively stone-age EJ. GDI allows for scavenging without a bunch of fuel missing the combustion chamber and going straight out the exhaust. Cooled EGR allows for a lot more knock margin than the engine would have otherwise. TGV allows for good fuel mixing even at low RPM with GDI. There's also part load Atkinson cycle operation.

Completely unopened engine, look up “the rumble shake” on Facebook

"Rumble shack"

Was a very fashionable place with the young 'uns at work when they were doing Subies a few years ago

Some moved to Pulse, which is why I sent mine to Pulse

Most of the rev head young 'uns then moved to VW or Audi's a few years ago, now they either have jacked up black smoking diesel 4x4 or Holdens and Ford utes and sedans with a mix of V8 and boosted Barra's

It's rare to see, or hear, a STI anymore

Really depends on personal preference but I think they are reliable enough to daily after owning a 2x Evo 8 GSRs, 2x Evo 9 GSRs, a X GSR and a X MR. The cars drive really well stock and with bolt ons can make 330-350 to the wheel with a good tune. Personally the X MR was really nice in traffic, had a lot of room inside/comfy, and was sneaky fast. However, it did feel a bit bulky compared to the 8 and 9. If you want something a bit more agile I’d lean towards a IX GSR. Although interior changes were minimal, I did like the extra comfort stock (leather seats) compared to the 8.

And I believe the 9 had mivec too?

Have heard this helps dramatically when tuning.

 

Haven't driven any other evos(apart from X mr's) but can imagine they would definitely feel bulkier, as they are much bigger in general.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
