Wotcha and welcome. Look at cooling the 4th cylinder & uprating your fuel pump, consider a fuel pressure regulator

IMO go for a high mileage WRX and spend the time fettling that, pull the engine, port & flow the heads, cdb / semi cdb match all the intakes manufacture your own screamer pipe, play with antilag setups research coolant mods and use it on the track until insurance is an option. That way you learn as well as end up with a serious piece of kit at the end

Welcome - problem is the additives you mention were to prolong the life of parts prior to wear, more of a preventative maintenance approach when oils were not as good / resistance to shear etc in high load mechanical situations You may well hide the noise for a bit but the wear already will mean tolerances are now looser and will continue to get worse

My lad is 20 and he was looking at 4 - 5k on a hawk wagon wrx, that was with a clean licence, now he has some points he is not even entertaining it until they come off

nice bit of progress there 👍

With those mods you would push you insurance up anyway? parts you will need off top of head are header and up pipe turbo oil and coolant feed lines piping intercooler and bracket Recirc valve and tubing ecu pressure solenoid / boost controller fuel system mods to accommodate increase in demand - pump, injectors etc. Engine work to lower the compression of the cyclinders - NA engines run a higher compression than turbo units You may also end up with issues with the chassis tying itself in knots as suspension, arb's etc will be overwhelmed then dependent on what power you get there may be issues with the clutch and differential possibly drive shaft links. I know the setup on my 2.0 NA auto is way way smaller than my STI but that is factory 150bhp tolerance vs factory 330bhp tolerance. The TD04 turbo may bolt on but as it is designed for a larger capacity engine you may find it will not work with your engine. A mitsubishi colt has a 1.5 turbo engine and runs around 150bhp as standard - these can get an easy boost to 200bhp with mild tuning however they have immediate issues with the standard clutch but looking at my lads 1.3 NA version against my NA 2.0 I can see the chassis is a better starting point in that car than the scoob. By all means it is your car and it would be great to see your progress in a build thread but I would suggest doing more research on the engine solution based on other 1.5 turbo cars to get volumes and calculations correct - I dont think it will be as simple as just bolting on wrx parts

Wotcha and welcome - Feel free to get stuck in, all friendly on here

Change of direction for the fuel system postponed progress there, so a minor change to the interior

Entirely up to you. You can start a thread in the build section if you would like or this thread can be moved / retitled. The benefit is as much for others who look to get guidance on their own cars as well as support / advice from the forum. Choice is yours

Every cloud eh - I know what you mean about the can of worms, just start one little thing and it just cascades into a whole raft of things

Nice set of wheels - GLWTS

Facebook has a large amount of groups which you are able to sell scoobs on for free

See if Bob Rawle is attending a dyno near you, travels and is highly recommended

Wotcha and welcome!!

Ahhh I see - got you 👍

If it was a geniune Litchfield they have used Bilstein shocks but they will have done springs shocks and a fast road setup. It may be worth contacting them.firat as replacing stuff without knowing what the setup was will screw up the handling

You probably know this but the 1000cc fuji racing injectors are 399 https://www.importcarparts.co.uk/parts-info?id=14275&cat=3678&sub=0&sec=0&var=0&dc=&gen=0&searchKey=&searchPart=

depends how much you want to spend - ebay? https://www.ebay.co.uk/itm/Middle-Silencer-SUBARU-LEGACY-OUTBACK-3-0-4X4-ESTATE-SINCE-2003-Exhaust-Box-YAX/372010614756?fits=Model%3ALegacy&hash=item569d8f7fe4:g:aKIAAOSwBkRaIA3f custom https://www.powerflowexhausts.co.uk/

wow how did they get through the filter, must have been like firing a shotgun??

pull the wheel off and get a thread pitch gauge on them to confirm and also see if the thread has been damaged https://www.importcarparts.co.uk/parts-info?id=7064&cat=0&sub=0&sec=0&var=0&dc=&gen=&searchKey=wheel&searchPart= £2.50 per stud

As above - contact an importer (recommended) there are a few that people speak highly of

!Removed! hell - a monster 😁

result!!

That is great customer support - nice to hear
