Possibily. I'll have a look. Went to check last night, apparently it's a bit more difficult than just uncoupling the two clips and pulling it off to have a look haha. Yeah, I didn't think it would be difficult to hit over 300 on the EJ25. Just a tune, considering the Jap and USDM is already at 300...anyone know the rough figures a tune would get on a stock EJ25? £400 for what? 40hp and about 60lbs of torque? I did ask the question and they reckoned it was a stock map. Boost hits at 1bar peak, so I really don't know. Been meaning to have a flirt with the 320FR Evo another lad at work has...if he walks me then obviously it's stock as he'd have about 35hp on me...mind I played with a Golf GTI that was tuned to 264 he reckons and I caught up to that quickly, and if I was stock I would only have 21hp on him, plus AWD and more torque though.

It's clever enough to read the octane though and that moves the timing accordingly? The better fuel and timing change would be why when people put in better higher octane fuel in cars tend to run better. An example would be putting regular fuel into a Civic and it gets say 45mpg. Put a better grade fuel in and you get 47mpg and a general performance increase. Makes sense about the JDM ones...but not about the USDM which has the same spec as JDM (and worse fuel by all accounts). Yep that's what I'm thinking with the pump. No idea how to check other than removing it though, and that's not especially easy at the moment as I have my son seat in the back and it involves removing seats blah blah blah time. Could move to front, but don't know how to disable airbag (fuse?) and I'm not too sure about that even as I haven't had it in for the recall yet. Don't want to mess too much with the safety stuff. Looks like you maybe right with the intake pipe. That's not what I would of classed it as, but terminology gets crossed easily you know, transmission/gearbox, hood/bonnet, etc haha. Any super big advantages to splashing on a kit like the HKS one over just a Cosworth panel filter that sits inside the air box? Obviously the kit would be better I'm assuming. From other car knowledge I'd say cold air would be best, but I lack the Subaru knowledge...K&N do a few different types (cold air, short ram, Typhoon (which I thought was the best). Not much room in Subaru bays compared to other cars I've played with! Guessing the zero sports but is one of the bits that comes on this: http://scoobyworld.co.uk/catalog/product_info.php?cPath=47_66_611&products_id=1235 So I could just go for something like this and it would be the same as the kit above (but with a Zero Sports part instead of a HKS bit) http://scoobyworld.co.uk/catalog/product_info.php?cPath=47_66_611&products_id=1234

From what I was lead to believe, the type UK was tuned down from USDM and Jap version. No idea why. Boost is standard across the board at 14.5psi from the factory, so it can't be that? I dunno though, that's why I was asking. I'll see if someone knows...probably not though, I scoured the Internet before posting to no avail. I was under the impression that the ECU could recognize the different octanes to a degree. Not massively, but the difference between say, 97 RON and 99 RON (V Power if you will). If you put 97 in the ECU automatically retards the engine a bit to cope with the fuel change, albeit it's not advised. As for the plans, I have no idea if it's got an updated pump. I really should check that. I know I've got a Sard FPR though so I have wondered about it. Filter is fairly cheap and easy so will probably do that sooner than later. Any suggestions on which to go for? I love the looks of the HKS ones but they're ££££. When I bought the car, they said it had a Zero Sports intake pipe, but I'm not sure what they're on about there because I just see abnormal airbox..I've got a cat back Mitsubo already as well as that came on the car. I have played with the idea of getting a custom map, but I didn't want to spend £400 on it and then buy something like a decat and need another tune...maybe I should just get the decats and then go for the tune...

Yeah I know mate. US measure differently obviously like you say, but I know that 93 Octane in the US (which is what it's advertised at on the pump) is 98 RON here in the UK. Almost 100% positive. Either way, the ECU should adjust for that. Yep, I knew that about the stock map. Literally, I don't plan on doing much for a few years engine mod wise, hence why I was thinking this. Maybe a new filter and that's it until I can sink a decent amount into a load of extras and then mod. I dunno, was just thinking outloud as I've got some contacts in the States that could get me a USDM ECU for cheap or nowt.

Aye? The fog covers are crazy prices like...but I want some haha. I'll ring Subaru and ask them when I get funds. Much more important things until then...

Looking good mate. If you don't mind, out of curiosity what did you pay for all that to be fitted? Did you provide the parts and if so how much were they and from where did you buy? Trying to find blue hawk STi fog covers is a pain!

Or tyres sqealing 😈

Well, this is kinda my thoughts. But I'm not planning on doing a rebuild for the next few years, so I was thinking Cobb and then use their Stage 1 map to get a bit of extra power as I only am using for generic application at the moment. I'd get a proper tune from someone once I did the full rebuild. Was just thinking outloud.

I'm sure this was discussed in the Holy MPG Bateman thread. US 93 Octane is like UK 98 RON. If that were the case, surely the USDM would be mapped with worse specs for worse fuel? The ECU should automatically adjust to the type of fuel you use.

Just out of curiosity, does anyone know if I grab a USDM ECU for a hawk STi and throw it on a UK spec STi will it work and run the higher settings? USDM is tuned to 300hp and 300lbs tq. Compared to UK 285/280 (or whatever it is). Just curious as to if it's possible to get cheap and easy power (like maybe flash the ECU to be a US spec instead of a UK spec. This also coincides with Cobb Acessport question I posted elsewhere. Instead of getting a proper map tuned in, grab a accessport and then throw a Cobb map on)

Have to tried looking at the Cusco catch can?

Does anyone have one of these? If so what's it like to use? Fairly easy? Is it worth picking one up to hoy a Stage 1/2 map on?

Damn good price.

I've used Millers in my STI, but used Motul in my old CBR. Both great, just depends on how deep your pockets are.

I have heard of it happening. No idea why it does though. Maybe it was warm from sitting and got hit by cool air quickly? No idea.

Thanks bud. It's not very tidy at the moment! Needs a good clean! Loads of little things to do, just need to put some time aside to do them (JDM hazard might, route Mic properly for phone, etc.) but for sure need to.

Niceeee. We need to meet up sometime. Find some nice roads ;)

Yeah I'm sure you can. There's a little bit behind one of the headlights I've heard. You need a screwdriver.

Hmm I'm thinking mine is missing/needs adjusting as well. I've got mine to go in still, but I was number 30 on the list! Say it's about 3 per month, and that was about a month ago. Figure I'll have mine done by 2019!

Why do you need chassis number? PM me.

Pretty sure stock is 14.5psi

Loads of places mate. http://www.amber-performance.co.uk/product.php?xProd=7274

@HoodedLime has a set of Eibach springs for sale bud. Would get the drop for the time being

Samesies! 😂 Mind since I met my lass I went through a small phase of not having so many tuneable cars...so I'm probably 6 years behind with about 1/2 the amount of cars haha

28 in May and bought my first hawkeye STI last autumn.
