Looking for a Diesel GT Blackline

Hi all,

Spent a few weeks stalking these forums for answers to questions I had regarding the diesel GT's.

To keep a long story short, my circumstances changed and I am now doing an almost 80 mile round trip to work (M3 and M25) - which means my currently modified Scoob has to go as I am bored of stopping at the Shell garage every few days - and it really is every few days! I also enjoy driving so need something which is fun as well as useful and pretty to look at - hence the GT. But the Impreza has never let me down with the only repair in almost 3 years of ownership being the rear calipers getting a refurb.

I am a keen modder so I would be looking at getting the car mapped when I buy at some point, coupled with EGR delete, the latter being a common problem being resolved, but are there any other mods that could be recommended that would decrease the likelihood of being stuck on the hard shoulder?

An upgraded clutch and silicone turbo hose are two things that would be on my hit list straight off the bat. Things like door leaks and window issues seems to be a common but easily rectified problem so nothing there. I understand that on stock GT's the front end can 'bottom out' but I have seen on both the cars I have looked at and around this forum are replacement wishbones. I don't know anything about the workings of suspension, so this could be a totally dumb question, but can this be solved by going aftermarket? PU bushes seem to be a good investment.

Is there anything else around the turbo that would help?

Thanks guys - I appreciate that this is quite an open and vague question and I appreciate any response. This isn't meant to antagonise anyone either. I genuinely love the look, both inside and out, of the GT and its uniqueness and rarity I love.

JTDm Blackline owner here, rocking at 160 mile a day round trip (80 miles in each direction)!

They're great mile munchers, and upgrading from my old Polo really has eased the commute for me!

EGR Delete is almost a must have, getting this done early can really help prevent a lot of problems down the road.. Other mods to help the longevity/reliability would include the silicone turbo hoses, removal of the swirl flaps from the inlet manifold... Also I'd get the cambelt/waterpump done ASAP if it's not had one in recent service history (a lot of common labour with e swirl flap removal mod, worth getting done at the same time)...

Not a lot of choices in aftermarket wishbones unfortunately.. AFAIK the general consensus is that you're probably better off sticking with OEM/Stock wishbones and then fit polybushes to them if you like, or else get into the regular habit of lubing up the original rubber bushes to help promote their longevity... Shocks and springs can be swapped out for aftermarket (Bilstein B4, B6 and B12 are popular shocks), or bin them both and get a coilover kit.. These tend to lower the ride-height however so won't help your ground clearance... FWIW I've only ever bottomed out whilst attempting to take my GT down a farm track (stupid choice), stick to actual roads and you'll be fine on a stock setup... One thing to mention on wishbones is the cheap eBay kits... Lots available, and lots of people reporting alignment/fitting issues with these cheap kits...

As for PU bushes the upper wishbones seem worthwhile, as do the ARB bushes both front and rear... The Eibach ARB upgrade is a very popular upgrade for handling, but not cheap or easy I'm afraid (involves dropping the sub-frame for the front ARB)...

Oil catch can might help the turbo stay healthy, but regular servicing and sympathetic driving (I.E. no red-line driving until it's up to temp!) will go a long way to keeping it sweet...

Consider getting an underseal slapped on too... for 80 at Autolusso it's a little peace of mind that you need not worry about the floor rotting out

OH! And pick up a spare clutch clip/pin... Yours will one day snap in the footwell and leave you with no operational clutch pedal... Easy fix if you have a spare in the car (or a hair clip/pin), but otherwise you're stranded....

Good choice

I think you've got the lot there, Mr Editor!

Actually, the only other thing I would add is to find your nearest well-reviewed independent Alfa specialist, and for jobs you won't be doing yourself, use them religiously.

Dealers are, by and large, expensive, and not as good.

I use Alfaworkshop and Autolusso, and can heartily recommend both. But they're not that close to you, so check out your options.

Finally, for jobs you are doing yourself, this place is a wonderful resource for good advice - you'll get to know who the good guys are, and there are quite a few of them.

One more thing - expect the clutch/driveshafts to start giving you trouble after a remap if you don't sort them first.... Pretty common for people with OEM clutches to noticed them slipping 10-15k after the remap, although this will be driving style dependent... Again if you're sympathetic you can expect a bit more out of the OEM drive-train...

That was really detailed - and quick. Thank you!

I've noticed quite quickly from my stalking the amount of info here and people helping each other out - it's crazy but great to see.

The first thing I did, as I did with the scoob was find my local indie. Thankfully I am about 15 minutes away from AHM which seem to get high praise. I think Autolusso have a place in Bournemouth but is a tad far for me.

I did walk away from a Blackline the other day - the sale price was borderline what I was prepared to pay anyway but had not had pump or belt done at 65k. Reading around here and the indie websites it was danger zone so whilst I would get it done regardless, it was right on where it should be and didn't want to take that risk. Would have been ok if the garage was close by but it was quite a trip!
