Would appear to be label-less! :- The car did have a new (second hand however) MAF fitted before it came off the road, but this was 3 years ago - and I don't know the provenance of the one fitted. Cheers,

It still runs with the MAF unplugged - but (even) more lumpy. I'll try cleaning the IACV, this looks like a simple first job. To answer your other question, idle is high and the exhaust smells super-rich from cold. Cheers!

Hi guys, As part of the general work on my project GC8 (thread below) - I'm trying to resolve an issue the car seems to have at idle. Essentially, it runs beautifully from cold, and when driven (any throttle application improves the situation). However when warmed up, the idle will drop to the point when it's struggling to run. This can manifest as the car stalling when the clutch is depressed during driving. As a test I've tried unplugging the MAF, this makes things worse. No check engine light is shown. To complicate matters as you might see from the build thread, the chassis is a phase 1, the engine/harness/dash/etc is later model (V6) STI. To me it seems like a sensor issue of some sort, possible air temp? I'm still trying to work my way around EJ20s. Any help gratefully received! Adam

So topped back up with coolant today, and it's stopped over-heating - looks like the airlock has gone. Oil is looking good too. Went for a little pootle round my private roads... Adam

Good hey! Current theory is that it's blown a head gasket and dumped all the coolant in the sump, where it's sat for three years. This is supported by the fact that it's been empty of coolant. Filling it up - the level keeps dropping, so I'm pretty sure it's going that way. Will get the engine out for a rebuild soon as possible. In the meantime, small job today, new battery tie down:- Assisted by my small helper! Adam

Not sure the oil should be this colour:- Much better:- And some new hose clamps, that actually tighten:- Adam

Small job today - replace the BOV hose. It looked like this:- Yeah, na. Replaced:-

Thanks! Once the mould was cleaned off, most of the paint is half-decent. Needs a load of shallow dents taking out but that's easy enough. Even the exhaust polished up with minimal effort!

Finally have her! She took her first trip in 3 years today:- Got her back and gave her a wash down:- She's definitely poorly though, dropped all her coolant in the sump by the looks of things. Will drain the oil out when it stop lashing down! Adam

Perfect, thanks chap!

Thanks - excuse the ignorance, but whats the requirement on the manifold, in terms of the wiring/dash? Still new to GCs :-) Thanks Adam

Update folks! Finally got back over to look over the car again today. Few more pics lower down. Dirty and needs going over as I thought, but straight and with plenty of potential :-) Spare Blitz Nur Spec was picked up, and is now for sale in the classifieds:- Other things I noted:- Blitz dump valve, HKS Turbo Timer Project Mu front discs VIN shows model number:- GC8C48D Which means its an Import WRX 4-Door. as far as I know from Impreza codes. So, some pics:- Front end, needs tidying and re-aligning:- Wheels are in perfect condition! Dirty dirty engine:- Much more to come :-) Cheers Adam

Hi guys, With my project GC8, came a really good condition (spare) Blitz Nur Spec exhaust. Cat-back, so it's a two-piece. Quick clean up for the photos, will polish up much better than this. Don't have the bung, but I may be able to get this from the previous owner. Any questions please do ask. Pickup only from Oxfordshire OX11. £300 ono. Cheers! Adam

Cheers fella! Build thread is up here:- Need to actually pick the car up next! Cheers Adam

Few exhaust clips:-

Thanks! It's a custom one, powerflow built at Silchester Garage near Reading. Will get some clips up shortly. Adam

It's a 1995, need to check the specific base model when I can check the VIN. I don't believe that any part of the bottom end of heads came from the base car, so a lot of this project will be discovering what's actually on it! There was a full set of build documents with the car, but these have been lost by the previous owner (I did see them so I know they existed!). Need to track down a good machine shop in Oxfordshire, any recommendations anyone? Cheers Adam

Hi everyone, Just starting this thread to document the build/rebuild of a GC8 Impreza I'll be picking up in a week or so. To cover off the history of this - a good friend of mine bought this car about 4 years ago. The car had been built up at that point (may even have been a thread on here) with an STI shell, Spec-C hawkeye engine (or just heads), rebuilt bottom end, front-mount IC, some rollerbearing turbo (not sure what), various bits. Went really well, then the turbo died. TD05-20G went in. The car was running some small diameter mag wheels and semi slicks, but friend wanted some 4-pots on it, so swapped out the wheels for some Imolas to clear the new brakes. Blitz Nur Spec came off as it was too loud, custom system went on. For a while it wore some flouro-green wheels before the Team Dynamics were bought; this is the only picture I currently have:- After a while, the engine developed a slight knock (we think), and the car was taken off the road. Here it's languished for the last 3 years, until being bought by me (it's actually got mould growing on it right now)... Soooo the plan is to strip it down, do the jobs, check out the knock and go from there. Hoses will need replacing, brakes will need refurbing etc. Depending on the condition of the bottom-end, it may just be bearings, it may be more serious rebuild, it may end up being a new short-block. Any advice on where to go with it gratefully accepted! Will get some pics up as soon as possible. Oh, and the Nur Spec comes with the car, and will be for sale shortly on here should anyone want it ;-) Cheers! Adam

Hi everyone! New member here, based in Chilton, Oxfordshire. Driving a Gen4 Legacy Spec B as my daily:- Just about to pick up a GC8 from a friend as a project car (build thread to come). Looking forward to getting involved - big shout out to @GeoffLeggy ! Cheers all, Adam
