Will see how I go on the stock fuel pump and injectors, but that will be on the list for the distant future after the engine dress up and exterior fun... it's never ending
My vehicle will be very different next HVC

I wouldnt tempt fate and run the stock pump if i were in your position....i feel its good insurance when throwing more power at a car

The idea was thrown around to do the pump but I kinda put it aside as a future upgrade

Got a fuel pump and filter from jack at Kobemotorsport
Got everything except the headers sitting in the shed ready to go, they sent me the equal length ones by mistake
And still waiting on the heat wrap aswell for the headers
Also will probably wrap the downpipe down to the cat (don't want to go all the way down or the wrap will be getting wet all the time under the car
Organised a dyno tune with Matt at the end of august
Way too keen for this
Anyone who's done these mods before have any tips or tricks to help me out?

Started with the HD sway bar links and mounts for the rear, also stiffened up bar
And saturday I finally installed the STI springs that I've been waiting for!
So ridiculously happy with how they perform!
I'll be honest I only bought them to lower the car, but had no idea they'd have that big of an impact on the responsiveness of the car, especially the rear end (links and mounts weren't much on their own but when the springs went in it was just on a whole other level)
Plus it sits low enough to look smick, but not so low that it scrubs out or scrapes on anything
Next step will be tyres... but at the moment it looks like I'll be waiting till mid august for some potenza s001's to come into stock, literally the whole of Australia is out of stock
And then finally the anti-lift kit
Then I'll get a good alignment and she'll be ready for the performance mods!

Great to hear you are liking the STi pinks. I'll be getting mine in as soon as I've installed my Whiteline bushes.
Looks like I grabbed my set of new S001s just in time then.
Wanting to buy/looking for: single genuine STi rim, genuine STi front lip, Corazon or Zero/Sports grille and another OEM grille
Can you hook a brother up? Please contact me now. I have cash ready.

And how are your tyres going? They're the rarest tyres in australia at the moment hahaha

Three sets; front control arm lower inner rear bushing (KCA334), rear control arm upper inner bushing (W63396) and rear control arm upper outer bushing (KCA399).
Pretty sure they're the right part numbers.
As far as the tyres are concerned, I couldn't be happier. Much better than what I had previously and managed to grab them at a bargain price from someone who worked for Kmart Tyre & Auto Service on club.liberty. I killed two birds with one stone and put them on my newly refurbished STi rims too.

So I'll have that all done this weekend hopefully

Good work. They seem to be in such high demand. Especially in the Subaru size/s.

just had a MASSIVE week, fitting the new headers and turbo, and then driving to coffs to get it all tuned
Everything layed out ready to go on

Turbo comparison VF46 vs VF52
Headers
Everything went smoothly and I had it all bolted up, started it, all sweet, went for a drive, all good
Got home and notice a little puddle of oil on the floor... cue heart attack
after taking everything apart again... and lots of stress
it was the oil return gasket
So I made sure to get it done properly, got a new hose, clips, new banjo bolt washers, and cleaned up the old gasket and used some gasket sealant to make sure of it
Put everything back together again and checked over and over and over again for any leaks at all...
Not and single drop
Finito
Steaming coolant off the heat wrap
spent friday night, all day Saturday and Sunday (gave up at about 4 Sunday arvo after the leak and decided to fix it on Monday) then all day Monday doing this little project
Literally as soon as it was done, packed my bags and off to nelson bay to pick up the Mrs on the way to coffs harbour
don't think I've ever driven so slowly in my life, taking care not to go over 3000rpm haha
Finally got some rest and relaxation
Skip ahead to Thursday
Tune day
So much nerves and excitement
Matt as usual answered all my questions, made sure we both knew what we wanted to achieve
loaded her onto the dyno and Matt worked his magic
So thrilled with the end result, Matt was happy with how the engine sounded, no knocks whatsoever (phew)
Went for a good run around coffs so matt could do a few little tweaks on the road
Happy with how everything went, and absolutely blown away by the added power
End result on the dyno
19 psi
Peak power is from about 4000rpm
Boost hits 16 psi just before 3000rpm, Matt said that the headers pretty much brought the spool rate to the same as the VF46 if not a little quicker
So that's perfect, exactly what I'd hoped to achieve
The difference is f'n AMAZING where the VF46 previously got to a point lower in the Rev range and just ran out of puff
The vf52 just keeps pulling all the way the 5500 with the flat foot shift limiter
Feels very VERY nice
Could not be happier with how it's all turned out
I'd like to give a HUUUGE thank you, firstly to Mr Matt Mcleod, for everything
Another shout out to Cameron for pretty much guiding me through the install
Most importantly my girlfriend, for putting up with my cranky attitude, and pushing me on when I thought I was about to lose all hope
And everybody else who helped me in whatever way with their knowledge on the forums and on the Facebook page
You guys are the best!
Now to enjoy driving this absolute beast!
And maybe start working on some exterior modifications so I can look the part aswell

Nice work mate, excellent build up. Such a great sense of achievement in the end and that it was all worthwhile.
I wish I had gone as far with my Gen4 GTB but I gave up, mostly because it was a yucky sedan!

Oh yea, wagons ftw haha
Basically the only reason I bought a wagon was I'd just recently started playing ice hockey and I wanted something to conveniently carry all the gear...
Best decision I ever made haha

Not really but it's cooked, most likely a big end bearing
engines being pulled apart as we speak to assess the damage, the end result will be a more than likely a full rebuild with cosworth pistons and rods... and whatever else needs to be changed
And a new tune
Hopefully the car will now be reliable and free from engine trouble for at least as long as I own it
