bare in mind your talking about a car thats 10-20 years old now so will have ware and tare on it. 140k miles is pretty high for the engine's in them (not that more isnt possible). Prices are going up and there are alot of sheds around. What sort of budget are you looking at?

your gonna get alot of differing opinons, but i would stay well clear of a guy called duncan graham, aka racedynamix, hes a proper cowboy.

you never want to do a headgasket on a 2.5 without doing the bottom end 😞

depends what you looking to push too and what your existing spec is? Also bear in mind you will be spending more on supporting mods than the turbo to make sure its reliable

prob wanna get some more details up, waht you think the value of yoru car is, some pics etc etc

are they doing the bottom end as well? Headgasket failure on a 2.5 is def bottom end rebuild job as well.

the uk 2.0 are pretty strong engines, so you should be able to run 400 without too much issue, bear in mind you'll need the right supporting mods to do it.

Hmm that's not so good, as above sniff test and go from there.

White smoke on cold start is perfectly normal. Is it smoking when it's warmed up?

if you are pushing it that hard your going to have to remove the stock safety features becuase the levels are above the visible limits, which you dont want to be doing. iirc the absolute visible limit of even the later ecu's is just under 1.7bar. You want to be below that level with tollerance so you don't overshoot, so in reality your limited to 1.6bar give or take. Bear in mind this is more a general comment regarding swapping to after market when you go up the power level. The boost control in the stock ecu is fine at lower levels of boost even on the early cars, although i agree they are showing their age, but at that point your then back to a case of looking at replacing the whole unit as boost control isn't the only issue. Makes external boost controllers a waste of money and setup time.

tbh £2500 is around where i would guess given your age. Most specialists wont go near you till your 25, Try the price comparison websites. Young + performance car = bend over and take it dry when it comes to insurance.

im on tein flex z so lowered, im not exactly sure what the height is set to tbh. Also need to take into account what the coilovers are as softer setups need more height or they bottom out. Afriad suspension setups isn't a subject im that up on.

So looks like rear wheel bearings might be an issue on these, dads is now 3 years old, but he had to have a rear beaing replaced when it was 18 months old (under warrenty of course as he bought it new), i'll ask him what the milage was and edit the post.

tad late, but decat and map tweak 😄 not posted in this thread for ages hahaha

no external boost control is needed on a subaru. By the time to stock ecu struggles to cope you need to go stand alone ecu anyway. If you need some extra way of controlling the boost then something is wrong or your at stand alone ecu time. Unlike old fords and stuff you can't just change the boost levels, fueling needs to be adjusted to suit so you don't fry the engine. Hence why additional boost control is a waste of money.

yeah, hoped for a little gain and maybe break 400, although wasnt expecting it too 😄

i just got escape from tarkov, man that game is brutal, dont think i have sworn at a game so much ever lol

If the bearings have failed due to low oil then it must have burnt a hel of alot in that time. Also the bearing failure is just an outcome, not the rot cause of the issue. 1L per 1000 miles is subarus official concern point, but Thats higher than most tuners will accept as being ok. If yours has done 2L in 1000 miles then something is serious wrong.

So got back from clinic, and just about thawed out, duck me it was cold lol Results are in and I'm pretty pleased with it. The boost went up slightly (about 2psi iirc, although forgot to get afr/boost graph so will confim) without any input from the mapper, map was generally the same other then a minor tweak in fueling. It gained 25bhp, 15ftlb and a nice amount of spool. I'll get the bhp/father graph up tomorrow as it doesn't seem to want to take it straight from my phone.

Best bet rip it out and have it mapped properly. No need for them on subaru as the ecu controls the boost.

could you get a video of the noise to see if we can hear it?

Knock typicly starts arounf 2k and can be a slight if its early stages. Compression test wont show you if the bearings are gone, I'd get it to a decent specialist and see what they say.

Is it a deep in the engine type knock? Or more tinny lighter type thing?

Glad you got some sort of outcome from it, but sucks you had to go that far.
