looking at P1's for sale, but many seem to blow their engines at about 60,000 miles.

is this usual?

most for sale are at about 45,000ish, so wont be long before big ££££

anyone reassure me this is not a trend??

Defo not the trend m8.....they only go because of idiots mistreating them...always warm up b4 some hard driving....always cool down after some hard drives ..and will last 4 ever lol
mine is pushing 360-380 bhp without any probs !

Perhaps its because at the time Prodrive werent able to remap the ECU properly to suit UK fuel; although they could now, recent PPP remaps are ECU-TEKs. To counter this they put some totally useless pellets into the fuel tank, similar to a 'Broquet/FuelCat' etc.....

changed 4 engines now in p1's all below 60k

christ - sounds a bit dodgy!

Doesnt it just?

They are no more or no less fragile than the STiV as they have effectively an identical engine and ecu.

If you de cat either of these and/or run them on poor fuel then there is a very good chance of blowing them up as they were originally mapped for 100ron. The original map has two particuarly "uncovered" points in the rev range and decatting, with the subsequent increase in air flow, takes these engines dangerously lean at these two points. So, a hot day, a bad batch of fuel, unusual engine load, whatever and you can get detted to bits.

Get one that has never been decatted (if you believe the owner and even then run it on the best fuel you can at all times - never NUL unless an emergency) or go for one with at least a knocklink and a good remap by a good mapper. My P1 runs on optimax plus 100mil NF race, and was tek 3ed by Bob Rawle for safety more than power ( still 300/300). I watch my knocklink carefully and if it gets lively I back off until I have increased the NF or put a fresh dose of Optimax in which usually cures matters.

other pointers

If the DV is "upgraded" make sure it's a recirculating one as the VTA also bugger up the air fuel ratios

MY99 Mafs which is what is has are also particularly fragile - I've had 3 on my P1 in 3 years - and these can also kill the car. Sti Panel filter is the best bet here.

All issues to be aware of , but not to be scared of.

62k now driven hard done 2 track days and a run to spain WRC all is good but i had a re-map!!!
same gearbox same cluch same engine service it well she will look after you well only the best will do

Andy-pay

looking at Subaru dealers cars mainly, with the all important warranty - although this wont last forever of course!

what sort of cost for a re-map then guys?

and who to get this done properly?

seems a bit of a shame to need to do this to Subarus finest though?

pslewis

The P1 is NOT Subarus finest, never was, never will be ...... don't get confused!

Its all about the MAF sensor - change it regular and you will be fine... And do a search.

Do p1s blow their engines.
more like what does pslewis blow?

Believe the P1 has more or less the same engine as an Sti V/VI, and there is a well documentated problem with these engines suffering from big end bearing failure. I know, cos my sti 6 let go at 40k. There are many people around with these cars that have suffered this problem.

An upgraded oil pump is allegedly meant to solve this problem.

Be careful cos when the engine bearings go, it's costly and very upsetting.

Dave

Dark Blue Mark

I dont believe its all oil pump related, they all share the same MAF sensor, including uk cars (MY99/00) and its well proven on here that they have caused many of these cars to let go, from lean running. Do a search, its quite a long / old subject.

D'ont think its ALL about the MAF, thats one of the potential problems.
ALL Scoob engines are fragile whether peeps want to hear that or not. On my recent 'more and more Scoob engine failures' thread David API said his company alone had rebuilt over 500 engines in the last 3(?) years.

Most main dealers say they rebuild about 2 a month. Thats a hell of alot of engines boys.

Out of 6 22B's I found for sale recently 4 had had an engine rebuild. One was on its third engine!!

Oh yeah d'ont drive the car above 100 pmh because the intercooler becomes inefficient. Its not like its a performance car or anything!!!!!!!!!(LOL)

Not even going to put flame suit on because the truth is the truth

IIRC you're making an innappropriate inference from the figures David gave. You failed to mention that he stated that 90% (IIRC) of his engine rebuilds were JDMs NOT uk cars. I still maintain that the most common cause of Subaru engine failures are the owners: e.g. poor fuel, lack of mechanical sympathy, general ignorance/lack of regard for basic maintenence issues. The sad thing is that a decent enthusiast is usally the one that gets landed with the bill, as they'll buy a JDM with a couple of previous owners, and generally have no way of telling if one of those owners may have scrimped with the octane booster or treated the car like a joy-rider. They treat the car properly, but the damage is already done....off to David at API

It sounds like Subaru may not have converted the Sti V engine in the P1 to run on UK spec fuel etc as extensively as they should have, which has been compounded by owners making mods to their cars or just getting unlucky with a bad batch of fuel.

Dark Blue Mark

Spot on NS04...

Agreed not all MY99/00 failures are MAF related, but more often than not its an issue. The P1 is a prob IMO, as the token effort of shoving a broqeut in the fuel tank was a bit half hearted, when the ECU should have been allowed to be developed by Prodrive. Add to this that, as NS04 says, people mod them and the MAF issue, and you have a big problem...

Indeed, so, if you want a P1 follow some simple rules:

1) Few owners as poss and speak to them to see if they look like they know what their talking about when it comes to taking care of the car.
2) Don't buy one with mods, unless it has been remapped to take account of them. It should also have a KL to give you early warning of any MAF related Det.
3) Ideally you'll go for one that has had a proper remap for UK fuel and a KL from the outset/early in its life as poss.

Should be enough to land you a good un'

Alternatively, save yourself a few grand, buy an Sti 5 and use the extra money for a remap and a holiday somewhere nice!

Many, Many Years ago a magazine said that these cars are bullet-proof IF (and this is the crux of the matter) IF they are NOT modified and pi$$ed about with!

Subaru design a car to do a job, reliably, for about 10 years ....... mess about with that design and its curtains!

Imported cars have no history and are designed to run in Japan ......... not here in the UK

I've said it before and I'll say it again ...... the very BEST Impreza is the One Owner, UK Car, with Full Subaru Service History, NOT modified, NOT raced, NOT tracked, NOT owned by anyone under the age of 40 - find one of these and forget the overrated P1 or Imported

You know it makes sense ..... if you want 350BHP - buy a car DESIGNED with that power in mind .....

My P1 has just had a new engine. It had covered 64,500 miles when it let go.

CAUSE????? oil pump NOT WORKING PROPERLY.

Bumnmer! Well, there's the exception that proves the rule eh!

Hope it gets fixed soon mate and that it hasn't put too much of a dent in your wallet!

So can you confirm for all the peeps here that you have abused your car? Fitted nitrous, run it on potato juice and put chip pan fat in for oil?
I doubt it.

Point proven I'm afraid chaps

ps sorry to hear about your engine matey

icon1425

Yeah i can honestly say that in the time that ive had my P1 (14 MONTHS), i have looked after it with no expense spared.
Obviuosly i dont know how it was treated before, but im afraid the p1 DOES go between 55,000 and 80,000.
I was told that by the subaru dealer. but unfortunately, not soon enough.
Now it will do another 100,000 if its looked after.
Should do after a £3500 bill!!!!!
Still for sale though.
