The r400 still drones a lot with the factory downpipe, some don't seem to care so maybe I'm just picky but it really bothers me. It's actually worst when taking it easy at around 3krpm while giving a small amount of throttle.

You might not like that exhaust, it's what I have in mine and it is super loud and droney. That downpipe should be fine. The 2.5’s all use the same exhaust flange and it is for RHD so no issues there.

I assume he just wants you to just run a line straight from the comp cover port to the wastegate port to check it opens properly to hold 7ish psi.

Yea getting a 3-port will remove all existing plumbing and allow the tuner to dial it in however he wants. Around 14 is what the facelifts with this turbo are tuned for from the factory so it isn't excessive, if anything your original one was making alot less boost than it should have on the factory tune.

14-15psi is about normal for those so wouldn't be worried. If you had the TD04 one set open slightly it would slow it building boost which may have meant you missed the quick boost peak they usually have.

Sweet, that’ll be a 3-port then, almost all of the factory plumbing gets ditched when you do that. Shouldn't be going to the BPV. Should go forwards under the manifold with the turbo inlet pipe to the factory solenoid, and then from there to a port on that inlet pipe. Hard to say why it's boosting differently without seeing how it's plumbed up after that tee. How high is it actually boosting? Could just be a restrictor pill in a line somewhere that isn't right for the new turbo but seems unlikely. Since it all gets ditched I wouldn't worry too much and just try keep boost down and check everything is tight in the mean time

Nah that should be fine short term. Where is that line going? Is transaction from the VF or swapped over from the TD04? Are you installing a 3-port solenoid when you get the tune done?

You mean it is left open to atmosphere currently?

There will be something different with the way the wastegate vac lines are hooked up, worth checking over that before the tune. It should behave very similarly to the TD04 if hooked up correctly.

This one is a legit example, or an accurate copy. Black brembo’s, dark interior trim, sti cluster, sti half leather seats, sti lip, dark interior upper. https://www.trademe.co.nz/a/motors/cars/subaru/listing/2721012224

Pre-facelift were gold and facelift were black. The one's I have on mine were from a pre-facelift tbSTI. Pre-facelift also had the upper interior black on the tbSTI’s but think that may not have been done with facelift ones. The interior trim pieces should be a darker grey rather than silver too.

Probably still a better option than the subtech. Yea the VF45 is twinscroll too. It's basically the same rough design to fit in the same spot, with the same exhaust components as the TD04 just with some minor differences as it is a different brand.

No idea actually. Haven't touched them since got the car, I've only done like 1500km

Not sure which is actually better. They're both much better than the auto specific vf38. For the downpipe I reckon you’ll be better off with a HKS one which should be 3inch the whole way. Is it catted? What have you got for the exhaust after the downpipe? The stock one or something 3inch?

Interesting. I've pushed them reasonably hard, say 40+ over marked corner speeds, on some long gorge roads and never had any traction issues.

@Deadmin Go on Instagram and look up a guy called duane cressy. He literally in the last few days has done a video walkthrough of how he did it in his car. It certainly isn't a quick and easy task though

Still very likely to get stung with GST and all that, just skip the extra crap that comes in when over a grand.

This is what @NTYCME is doing right now from Ultrex. Pretty sure he still has a spot or two left.

It’ll still work but without shrouds covering the core properly you'll have a heap of air going around it rather than through, or if you extend the factory shroud you’ll give up some of the new cores surface area. I'm sure you could with some trial and error merge that shroud to the factory one to get the best flow across the whole core

Fitment to the engine will be fine as the same style turbo and intake manifold are used but the shroud shape and dimensions will be all wrong for the Legacy hood scoop.

There are issues with 6speed shifters as there are two different styles out there but haven't come across any with 5speed ones

Yea that looks right. Horrendous price though. How urgent is it? Could you wait a week or two from partsouq.com @Gripless He’s in a Legacy so probably not the same TS gasket you might have sitting around.

Nah they're definitely different. The one you need looks like this

How does the boost control set up look? Wonder if half of the weird ass Legacy TT bits are still in there messing things up

You should sell me your underseat one to fund something bigger 😉
