Gen 4 2.0L turbo Legacies are all twin-scroll turbo 38mm headers vs Impreza 42mm Different flange and up-pipe bracket iirc Prone to running bearings and turbos

Yes. Most (all?) BP/BL Legacys are twinscroll. I have a set of the headers off one in my garage. The headers are slightly lower diameter than the STI ones, and have a different flange at both ends of the uppipe.

Correct, marginally smaller. Apparently good to ~380wkw, but that's kinda internet mythology. I'll be running them with my baby BorgWarner, looking forward to the reliability and awesome heat shielding of OEM parts

No idea but that look would be crazy handy for someone wanting to do a piggyback Link.

VF38 turbos only came on the 03-05 EJ20X (automatic) Legacy's. 03-05 EJ20Y Legacy's are TD04. Then 06 is VF44 for auto & manual, and VF45 for 07-09 auto/manual.

Dude the NT03 have free shipping! I reckon they'd look mean on a 3rd or 4th gen. They're the same wheels as the 4th gen photo I posted and the wheels on the front of this B4:

4th gen onwards are twin scroll. Smaller extractors than the sti ones though. Legacy twin scroll headers are what's on my car. Sent from my SM-G960F using Tapatalk

I think 4th gen look best on decent width18s with a chunky tyre

Have seen a few over the ditch. Keep in mind that: 1. you'll have to run a lower profile == harsher ride 2. more expensive tyres

Had the same with my BR9, a full set of coils from Partsouq fixed the issue. Weren't particularly cheap though..

Didn't happen after that box was removed did it?

Evening subie gang I recently had my Legacy GT 2007 Reflashed and when the tuner was getting to it he noticed the below attached to the ECU which he obiously pulled off so he could remap mine properly Anyone know much about it or seen one? it was only imported to NZ a year ago and Iam the First NZ owner so obviously came from Japan like it Obviously some sort of ECU chip to get a bit more power out of the car as I noticed when I first bought it it definitely pulled a lot better than all the others I test drove

He couldn't tell me specifically, would have gone over my head most likely anyways haha.

Asked a mate who's an importer and said these are mutli point ignition systems. Sees them on a bunch of cars, they are done by orientworks. And they do tuned ecus also such as https://www.croooober.com/en/item/8587762/ECU/Orient-Works-RESULT-MAGIC https://www.google.com/search?ei=__pRXLyTPJLd9QPT2aK4Cw&q=orientworks+result+magic&oq=orientworks+result+magic&gs_l=mobile-gws-wiz-serp.3...7962.8313..8880...0.0..0.243.1472.0j3j4......0....1.3UiakxA-SgE#imgrc=enTrjPkDmeDwGM:

Does such a thing exist?

Damn that's a nice looking b4

Headers are the same, vf38 turbos are S***. Sent from my SM-G960F using Tapatalk

vf38 are the ones that crap out a lot, TD04 twin scroll variant are ok Yea ID of legacy is smaller

You want more width and/or less offset for the 5th gen. 18x7.5 +55 offset won't look good at all.
