Subaru Legacy Outback (JDM Grand Wagon) AKA The Daily Driver
Why is there smoke coming out? Hmm. Seems one of the heads is leaking oil onto the exhaust manifold. Better fix things before I set it all on fire. Fitting new rocker cover gaskets, cambelt, seals, idlers, etc seems to have sorted it. $985 NZD.
The car is basically a Legacy Wagon with too much suspension. It's got a 2.5L flat four, with a four speed automatic gearbox. It's a 1996 model, so it's getting a little tired now. Blew out a head gasket driving to work, so time for a freshen up!
Chassis
-
[KYB Excel-G] struts.Done. $620 NZD parts. $300 NZD for fitting. Car feels more stable on the road and much safer. - Polyurethane bushes.
-
[Whiteline] sway bar links.Done. $265 NZD. Huge improvement. Less wallowing and better turn-in, even with old shocks. - [Lovells] +1" coil springs.
- Whiteline sway bar mounts.
- Whiteline sway bars.
- Whiteline tower braces.
-
[DBA Standard series] rotors and EBC Greenstuff pads.Done. It now stops better. Would get the slotted rotors next time though. - [BBS RGR 18x7.5] rims in Diamond Black finish (or cheaper copies).
- Michelin Pilot Sport 245/45ZR18 tyres. We have some Pilots on the horse float. :)
- The wider tyres need spacers to be fitted. Eibach has some nice ones that will meet NZ regulations.
- Subaru VLSD rear diff and axles. Procured, just need to rebuild and fit 'em now.
- New steering column UJ. Whaddya mean you shouldn't be able to move it around by hand?
Engine
- Rebuilt original EJ25 DOHC
- Internals
-
Full rebuild, with new rings, bearings, head bolts, and front end components. -
Kelford "Stage 1" DOHC regrind cams [camshafts] $570 NZD + a shedload of time setting the clearances

Really need to find a wiring diagram for this car.Diagram found. 450 Euro = $800 NZD - VEMS Lambda and EGT meter.

It should look something like this...
Subaru EJ25 DOHC Genboard v3
Grandwagon needs a Genboard...

- Marcell, sounds like you've got it under control, but if you need anything tested/verified/measured for the Subaru system please let me know.
- of course, we do. If you could add subaru trigger support to /svn/firmware/utilities/testing/signalgenerator/signalgen.c or supply sufficient stereo wavs (or mp3) for a wide RPM range (like a 2 min sweep 100..12000 RPM would be fine)
Subaru trigger support now added to signalgen in SVN. A zipped output sample is online at http://www.vems.co.nz/signalgen
It looks reasonable in Audacity, but my motor is in parts so haven't compared to a real engine yet. I used Duncan's diagram and Michael's images for reference.
I'm not sure exactly what cam_start_pos is supposed to do, so this may need to be added.
