Hi guys I’ve just bought a 10 plate Subaru wrx-s at 51k on the clock, does anyone know of any problems on these engines I’ve heard mixed reviews on these just wanted some feedback or any advice On what if any modifications I could do
i would keep it stock and keep on top of oil changes tbh, others may have other things to say but thats my 2c. ericmcn said:

Yeah I’ve heard to keep it standard and look after it and it should look after me, I’m only looking to make it sound a little better and is it true to only run it on 97 petrol?
I believe so, best idea is to pop over to UK Legacy where you will get much more detailed answers. I have heard too many horror stories from these cars so would be reluctant to fanny about with them - I use Shell V power all the time in my Legacy and dont see why anyone should be skimping on fuel - its not like you are driving a Matiz 
It was mostly the 08 / 09 STI that had the ringland and HG issues due to a poor map as I understand it. I'm no expert and there are people here who are better informed than I.
I did have an 07 WRX (2.5) for a year or so, the WRX's never really suffered unless they were mapped to silly figures, or mapped by an idiot. Mine was standard and is still going strong on 93k to the guy I sold it to, all I did was ensured that I ran it on decent oil, serviced it once a year and ran decent fuel (Momentum 99 or Shell V Power is the ideal stuff to run it on).
The Subaru has a map which "learns" the kid of fuel it is running on after a while (so I'm informed), so if you run it on 95 or crappy Sainsburys 97 / BP 97 then you will notice a slight decrease in performance, as apparently not all high octane unleaded is the same...
The concensus on Scoobynet is that you can safely map a 2.5 WRX to around Sti figures (which is what the PPP would have given) around 275 as long as it's done by a decent company and you do the normal upgrades, exhaust / filter / Walbro fuel pump / Map. Should give you a reliable daily driver without too much of a thirst.
Again, it might pay to do your own research but I seem to recall somewhere that if your 2.5 engine hasn't let go by now, at 51k, the chances that it will are very slim (thats the mileage I purchased my 2.5 at).

My 2008 330s let go at mid 50's with ringland/hg failure with the previous owner and he'd maintained it perfectly. It then let go again at mid 60's in my hands due to a failed oil pump. Nice!
Such a shame as a great engine when working well.
Yup. You can't really sleep easy with any of the 2.5s. They're all a gamble to some extent.Such a shame as a great engine when working well.
Head-gaskets are mainly due to thinner walls on the block than the 2.0, so the year of manufacture is irrelevant. But yes, if you increase the boost then it'll make them even more likely to go.
