this seems to be a very common thing on impreza's how can u prevent it from happening! mines gone im having a new engine fitted in my sport its cheaper that way! every site i go on someone has that problem! or a few people do.


i cant believe how many there are

Not as common as reading boards like this would lead you to believe. No-one posts to say their scooby is fine! Terminal failures are also more common on imports, where fuel quality can often be an issue

David at APi recently gave advice along the following lines. None of this should be a surprise to anyone who cares about their car.

1) Use the right grade fully synth oil
2) Warm the car up before extending it and let it cool off properly before switching it off
3) Decent petol! Preferably optimax
4) Keep to the service schedule and get it done by experts
5) Don't bounce it off the rev limiter or V-max the car for prolonged periods (not that you could really do that legally on UK roads anyway!)
6) If you're gonna mod, get it done properly and have a remap to account for the mods.

I'd add that you should also pay attention to the car, very rarely does something just go without giving you some indication that something isn't quite right before hand! If something doesn't look, feel, sound quite right
it probably isn't. Find yourself a good specialist and get the car to them to be safe.

Follow that advice and you could consider youself very unlucky if you have any problems before 100,000 miles at least!

I VERY MUCH AGREE

IF YOUR GONNA DO TOP SPEED RUNS I RECOMEND OIL TEMP AND PRESURE GUAGE AND A OIL COOLER

that way you can keep an eye on things and lower the internal temp of your engine so you dont melt the big ends

Yup, top speed runs are risky IMO. If i ever go over 100 is only for a very short time. Would never dream of pushing my car to the top end limit.

The problem IIRC is that the std intercooler scoop on the classsic cars just doesn't work very efficiently at all over 100mph. Up go the intake temps under conditions when the engine is under a lot of stress and pop it goes! I know that you can buy splitters that force the airflow over the surface area of the intercooler....I don't know if there is any empirical evidence for their effectiveness. A FMIC would solve the problem presumably, but thats an expensive fix for a problem that really shouldn't be an issue for most of us, most of the time.

Unfortunatly, the above doesn't help the man - It's a sport!
Assuming the intercooler airflow problem is not an issue, an Impreza (turbo at least) should be capable of cruising at 100mph, after all it's only around 4000rpm I sometimes wonder if the development of some cars goes far enough before production?

Hi,

Felt I just had to say a few words regarding the Scooby engine.

We run a total of 3 Group N (Production spec) Imprezas plus 3 recce cars.

Admittedly the engines are rebuilt once we get them and we balance /match pistons etc etc.

These car run on the limiters for over 300kms on each WRC round so they get quite a pounding.

Now, we run a high octane fuel that you cannot buy at the pumps and yet we only push out about 295 bhp. We also use the very best synthetic oils that we can....heavily tested by people like Shell for us.

Bearing (sorry about the pun) in mind that many of the cars out there have been tweaked to figures far in excess of our bhp's it is a wonder that any of them are staying in one piece.....the fuel grades available at the pumps are in no way sufficient for the power that some of you guys are claiming. You must be getting horrible detonation if your claims are correct.

Someone has already mentioned correct settings for the ECU. We are able to run the engines at various levels of performance enabling us to use Turkish crap fuel or Shell FIA grade all by having the correct programming for the ECU. Remember, it is all very well tweaking an already powerful engine but spend a little extra to set up the ECU to suit, a) your tweaks, B) the fuel available, and C) what you want in the way of economy.

Each of our rally car engines is rebuilt after each event. However our recce cars will last a whole season, even though they are driven hard and we use pump fuel. The reason? We use correct programming of the ecu for the octane available at the pumps in each country, superb synthetic oil, but most important of all.......no car moves, nor is it revved over tickover for at least 5 minutes at start up. Nor is the car switched off without sitting at rest on tickover for at least a couple of minutes.

These are standard cars so we are just the same as most of you guys.....take a little time to look after your baby and in theory she will not let you down.

Have it serviced properly, use the correct oils, remember the rules at start and stop and if you are doing a lot of town driving change that oil more often. £35/45 quid on oil beats £3500 for a new engine.

By the way we have never run a bearing yet !!!!!!

Whoops, missed that bit! Well, some of it still applies!

pslewis

Nothing wrong with these cars if they are looked after - simple as that!!

Proper services - no need to be a **** and do the **** Bollox - just do it regularly!

Don't modify to stupid levels, getting 350BHP isn't clever, it isn't funny and it will **** your engine!!

Treat the car properly, don't drive like a ******** and only give the engine a good stretch when its HOT and ready .......... allow it to cool properly for at least 5 minutes!!

Basically, if you are a pratt you are going to blow your engine!! Excusing those who have just bought and its gone bang, of course!!

Moral of the story??

Do NOT modify and CERTAINLY do NOT buy a modified car!!

Buy one with FULL history!!

Buy a one owner car and meet that owner to confirm he/she is a mature driver (thats NOT an age limit, its an attitude limit!!) some 40 year olds drive like 17 year old ******!!

These cars go on forever!! You only hear about the ones that have gone!!

You should cross the border mate, 100 ron fuel is available at the pumps.

Is there a big scooby scene in Cyprus at the moment? I put my scoob into storage before coming out here cos the roads/dust is crap. Be interested to get into the scene though if ther is one.

Not sure the extent to which this stuff applies to the NA Impreza's but...

Not everyone would agree with uncle Pete's views on Mods, but he certainly has a point on the other stuff.

There are, I'm sure, instances when well looked after examples let go, but this is the minority of cases! The great shame is when a previous owner has inflicted the damage only to pass it on to someone who cares for the car only for it to finally let go in their hands! Every performance car comes with that risk though! I think in most cases when a major failure like this happens it's for a good reason!

-Run on the wrong oil/petrol
-Driven like Colin Mcrae....without the talent!
-Not serviced properly.
-Not driven with a shred of mechanical sympathy...lost count of the number of people I've seen giving the car the full monty straight from start up or stopping it without allowing any time to cool down.
-Badly modded.

I have got a BIG END

Should i contact subaru to see if there is a product recall on them ???

Dave,

Sorry, although I am based in Cyprus the Syms PWRC Team operates from a head Office in Japan with a European base near Brussels.

I am the lucky one that can operate from a home in the sun.

I do not personally own a Subaru here on the island, but there are plenty of owners, using imports or genuine importer cars. There are several I believe with Army or Air Force personnel.

On the rally front many of the islands cars you will rarely see other than on events, as the "sport duty free rules" they run under require them to stay in bonded other than 15 days prior and following each event.

Regards to a scene, I doubt it !!!

With regard to the dust and crap roads....obviously a problem but regular inspection and renewal of the filters sorts one of them. As for the roads, they are not that bad.....in fact there are some fantastic roads where even an old codger like me can give my mates Carrera a fair old thrashing.

Even my placid old "Family" beemer gets to blow out the cobwebs now and then.......as long as the wife does not catch me.........

dont know where you live on the island but if you ever fancy a noggin or two.....get in touch. I suspect my son will be closer to your age ....(wild guess) and he used to have a Richard Burns version the UK.

Talking of Richard Burns......Does anyone have any news. My last info was he had had another operation but was still very ill.

If anyone knows more I will be glad to hear as I knew him when he very first started out with Dave Williams in his Pugs in Craven Motor Club.

Pretty sure its like most performance engines - if well looked after and not caned all the time, they will last OK. You have to remember that as standard the Impreza ( Turbo at least ) engine is already tuned and producing a lot of power - tuning it EVEN MORE is always going to reduce the reliability - hence race cars having engine rebuilds between each race etc...

I'm pretty sure 90% of the big end faliures are more down to either someone fiddling with the engine, not looking after it or driving like a nutter all the time, rather than any inherent design problem on Subarus part.
