my brother has just sent me this link it might be worth a little read!

May I ask why Subaru won't honour the warranty? Has it been modified? Or is it damning info from the black box?

I find it a little worrying that this problem continues when all Subaru would have to do is fit some forged pistons and tighten or uprate the studs. Well, I hope that is the fix. Or else I'm heading for one hell of a bill.

Good spot on the import tuner link, it mentions a lot of what David and Alan say (apologies to anyone else such as the above who may have also said things along the same lines). Not so sure I agree with Mr Crawford about the 2.5s running 400whp on stock internals but I am a regular layman!

Alan obviously takes it a step further - I reckon he is bang on about the emissions guys, ecu guys, piston guys and accountant guys not singing from the same hymn sheet with regards to design as they all have their own goals and objectives when designing and building.

Quoted from the article above. with a few added comments.

1/ The Subaru EJ-series engines are put together very well from the factory. Though not equipped with forged internals, the factory engine in its stock form can handle double its factory power output.[/I]

Yeah right. No further comment required.

Answer/ So an STi 5/6 engine will take 560 hp as built, Where do these yanks get their ideas from?, unless of course they run cars over there from 180 hp...... which would still stretch the con rod bolts in a 5 or 6

2/ The most common is believing the block needs to be sleeved. Most people jump right to them at 400+ whp but sleeves are not needed until over 550+ whp. OH!! what a good idea!, lets try to run a standard semi closed block as-is at 550 hp!

Answer/ Lets see if we can get it out of the workshop......

3/ We at Crawford Performance will start this by stating the number one issue responsible for the damage to Subaru engines is the free software available on the internet to modify the tuning parameters within the ECU. There is plenty of bad advice going around but the most common one I hear is "the bigger or looser the piston or bearing clearances, the better the engine will perform." Another is about larger pressure/volume oil pumps are always better because the factory oiling system on the EJ motors are inadequate, when in fact, a high-pressure oil pump can cause oil cavitation while lowering the ability for any oiling system to work efficiently. Another falsified fact is using a lower-temp thermostat will make your motor run cooler in hot weather but in reality it will have zero effect on increasing your engine's cooling capability. Other falsified facts include tuners believing that installing 1mm oversized intake and/or exhaust valves over the stock size valve seats will increase cfm airflow, and the best of all that makes me laugh every time I hear it is "you can make 500 whp safely on pump gas."

First sensible thing I've heard.

I understand that a non OE rear silencer box caused the engine failure !,
although all the cats etc are in place.
Any excuse not honour the warranty & grab the situation that so many people are walking away from Subaru, if they had only put a fix in place even at dealer level to fit decent pistons & alter the map accordingly to the already first time failures, which there are several cars to go on & fail the replaced short motor, this is from personal experience via my customers, the bigger picture must be quite alarming.

So are you getting as many in for repair since the re-call map as you did before Paul?
Could some of the damage have already be done prior to the new map so was waiting to happen? I noticed on one of my failed pistons apart from the chunk of ringland broken away lots of small cracks.
And were these cars standard if not what power levels were they running?
It's very disappointing to hear the later saloon STi still suffers from this issue.

While your here, mine's still running like a dream after nearly 4k since you worked your magic

Re call map, if a 2010 car has'nt been caught in the recall from 2008 its a very bad reflection on IM & its dealers.
Nice to hear yours is as it should of been from the factory.

thenewgalaxy

That's one of the most ridiculous things I've heard in a while.

Maybe they would refuse a claim because third party mudflaps were fitted too?!

Check back a while ago, the Subaru dealer checklist for warranty claims was "published" which included seat position etc. !!

more info is here...

My dad had the XR4i (1984 A-plate) had it from 6months old and swapped it in 1997ish for a ST24.. which he still has now! wish he'd kept the XR4i as it had only 86k miles on it and was offered £1k px against the ST24 Mondeo
Thing was it was still running on 4star fuel and the cost to convert would have been worth it. Knowing what we know now.. it wouldn't have been a problem.

Back to the engine problems... how do you kno wif your car has been map updated by the dealer? I take it when it goes in for service they check for updates and do it accordingly as and when?

thenewgalaxy

Are you serious?

How could seating position affect a warranty claim?

Dunno, but there was a 4 page form for the tech to fill in ...

You've only to pop the bonnet catch to be told by a subaru dealer ( you've f@@ked your car ) if you want a warranty that stands leave it stock

Well I wasnt aware of any saloons going as yet! Oh well good job i bought one with a forged block to start with :-)

What would be nice to know from Alan, David and Paul is how many have you guys seen so far?

Don Clark

Proboably said it before but still believe a lot of people are using the wrong grade of fuel.

Both Handbook and Workshop manual state that a MINIMUM of 98RON grade fuel to be used in the STi.

One good reason for getting the thing remapped either by Subaru (320R/340R) or independent mapper so that it can run on 97 + RON...........

APIDavid

I'd do that differently and map it properly on 99 [ Tesco or Shell ] as it will always do better mpg on better fuel to the tune of 2 or 3 mpg. [ we've proven that many times in the past ] .

They run like a bag of poo even mapped on 97, they just don't like it [ Don't get me started about BP in any Subaru - Just don't do it ]

So map it properly on the best fuel and enjoy it. Not all mapping has to be for ***** out power...........

Not had any post Hatches in here yet.

Tidgy

just out of interest, was there any reason why it was 2008 onwards?

mine was a 06 wrx that suffered ring land failure at 60k

APIDavid

iTrader: (4)

It seems worse on the hatches for oil pick up pipe failure. All the 2.5 STi's do the ring land failure trick no matter the model, it's about the Hypereu, hyperute, hyperteu. ---

BULLSH*T pistons.

Tidgy

haha, mine was a wrx so didn't even start with them lol

nice scoobyclinic built forged 2.5 now though

booked in for connecting the actuator and mapping the sc46 on 5th april, cant wait

chopperman

Hypereutectic piston.

And yeah, there crap. Subaru say they use them so they can run tight cold clearances and reduce piston slap. My forged pistons are as quiet as the standard ones ever were to be honest.

iTrader: (2)

The Mahle 4032 material piston, honed correctly can be a lot quieter than OE Hyper...., bullsh*t pistons.

chopperman

As i said Paul, mine are as quiet as they ever were so i can vouch for your above comment

salsa-king

but you still have skinny wheels and it's still NOT a STi even though it's got 480 bhp lol

Tidgy

hahaha, just cos your STI is slow

Up until last week I was on the verge of buying a brand new UK Saloon. Whilst I had some minor concerns, after speaking to David I was finally put right off the idea! I'm also having negative feedback on the 340R conversion as well.

It's a REAL shame as the Saloon is a great looking car and drives very well. However I can't plough £30k in to a 2nd car that could potentially rip it's **** out within 3yrs, or I have to be gentle when I drive it, on the off chance it could let go. That's not what car ownership (especially a enthusiasts car like these are) should be like imo.

Better the devil you know and she might be coming up to 8yrs old now, but the JDM Newage STi is one sturdy motor.
