  1. To start with, those P/Ns for the injectors don't follow the part numbering for Subaru that I'm familiar with.  You don't usually see letters at the end of the number.  Could be a Euro thing, but my suspicion is that those numbers are JECS numbers.

    I don't have any uninstalled injectors on hand, but my catalog lists Turbo/MPFI injectors as: 16600AA010 for MPFI and 16600AA000 for Turbo engines.

    Awesome, thanks a bunch for your opinion and tips. With that set-up, do your tires fit inside the wheel wells then? Like the stock ones do? I don't really want to go over 15" wheels so I will still have plenty of sidewall to be able to air down a bit when need be. But 15" steelies from Subaru's would be real easy to come by. 

    Did you get hubs off an xt6? or do the conversion? either way, what was the process like? 

    Thanks a bunch!

    The RS wheels do tuck inside the bodywork, but to a lessor degree than the stock wheels.

    MY EA82 has the XT6 conversion.  I didn't do the install, but it's pretty straight forward, IF you can find the parts.  Do a search, someone has done a writeup.

  3. Pretty sure Euro EA82Ts didn't have catalytic converters.  They weren't required in Britain until the mid 1990's.  I think the ECU may also have been different than USDM, but this is all conjecture.  Lots of EU-based members on the Facebook groups could answer this easily.

  4. There are three options for wheels on EA chassis, as I see things.

    Option 1:  Run 4x140 wheels.  There are lots of options out there, but they're mostly 13x5.5 and can get expensive if you have to import them.

    Option 2: 6-lug conversion.  Most of the 6-lug wheels will have massive offsets and won't fit like the OEM wheels.  This is the worst option, IMHO, but also the least expensive.

    Option 3: Subaru 5-lug conversion.  I run this setup and currently have 16x7 2.5RS wheels with 205/45/16 tires that don't have too much offset and don't rub.  This will be the most expensive option as you need to replace the hubs with XT6, or custom machined, hubs to fit the impreza/legacy/forester/STI lug pattern.

  5. Running on E85 is a great idea that would not only cut cylinder temps (reliability +) but with the appropriate injectors and pump, you could make more power without much work outside of tuning. Only downside is availabilty, tuning for lower than 85% E, and the slight dip in fuel economy vs. gasoline, but a worthy trade IMHO.

    That said, the easiest and cheapest way to make power on a turbocharged engine is with boost.  While staying at 8 psi and upgrading everything else to find gains is noble, it's the wrong way to start eating an elephant.

  6. That D-Sport article is suspect.  They show fancy looking graphics and charts, with no attribution or explaining how they got the numbers presented.  This leads me to believe (using my journalism background) that all they did was interview a TBC company, borrowed some "data" from those companies, and published the article.  In fact, a quick scan of the article shows mention of SwainTech Coatings.

    Now, to be fair, SwainTech is THE BEST company you can find for this sort of thing, anyone else is just a pretender.  The uppipe on my WRX has their White Lightening coating and while I'm sure it helps (I never did any pre/post testing) I would NEVER touch that pipe when hot.  These coatings are thin, and even the best TBC isn't magical.  You can't cheat the laws of physics, and (using my vehicle design engineer background) there is little chance that SwainTech's coating will prevent an EA82T cylinder head from cracking under extreme use.  The root of the problem is the design of the heads, hence why FHI revised the casting twice during production.

    I have seen White Lightening pill, bubble, and flake, but at a MUCH slower rate than other ceramic coatings.  I had my COBB Inconel uppipe coated in 2012, and it's not flaking yet, but has pilled where I had a minor coolant leak drip onto the pipe.

    Best/cheapest way to up the output is a big intercooler, a mint cooling system, and to crank up the boost.  Anything beyond that (custom pistons/rods, head porting, etc.) gets expensive quickly.  There's a reason these engines aren't plentiful these days, and it's because they weren't particularly reliable, even when new...

    OK, all that said, it's your money and your car.  I'd love to see someone push the limits with an EA82T, just be aware that with such a compromised cylinder head design and such a low specific output, you will quickly reach the point of diminishing returns in terms of output and reliability.

    bad turbo, getting a new upgrade soon,  and got ahold of an old ea82 header designer...

    Who was that?  I have a header made by forum member BoostedBalls, and a couple of TWE headers and downpipes.
