What happens if you blip the throttle? Does that noise change note? First thought is an exhaust leak somewhere
It does sound like increased vibration of some metallic ticking. Sounds like its coming from the middle between the y pipe and start of the catback. checked the bolts are tight, and nothing feels like its loose or can move.

I just installed an invidia r400 today, but now theres a strange ticking noise, not sure if its me and I didnt notice it befor or an actual new issue. Pretty sure the gaskets were put in their correct locations, i tried to wobble the exhaust and dont see anything or feel anything loose. Any insight would be appreciated. Wobbled each individual exhaust tip, they dont move or make any sound at all.
Thanks.

Hey guys, my check engine light intermittently on, randomly on and off. When it does come on, i step on the gas, and cant feel turbo come in, it could either mean my transmission doesnt wana downshift from 4th (its an auto) so it takes 10 years to rev up and gain speed at low km/h until it hit thats 2.5-3k rpm mark, or my turbo straight up feels like its not coming in at all. But usually it just turns on and off fully randomly, when it turns off the car acts like normal as if nothing happened, turbo feeling 100% there. Ive also tried to force it to 1st and 2nd gear when the check engine light is on, nowhere near as responsive nor feels normal at turbo rpm. This has been going on for months now, and nothing bads happened to the car yet, theres no code that tells me anything about an engine issue either, it really realistically feels like the turbo fins get stuck and dont wana work, then suddenly it gets some lubrication again and unsticks itself and spools. No clue whats going on, perhaps someone has some insight or ideas? its a 2001, dont really want to replace turbo, or take out turbo, or check anything by taking anything apart. Other then that the car has no other issues. Im able to live with this issue, it just feels like a 60hp turd when the cel light comes on, then randomly it goes off and suddenly boom back to normal ~260 hp. it only happens when the CEL is on so i assume its most likely and issue. I need some opinions or if anyones ever come across this before? thanks for reading this huge post.

was peak boost the same?
Yea peak was the same, however primary I don’t feel any pull anymore, a noticeable amount less than pre mod. I switched out the hose to one from mani to bov. And the blocked off the t with a bolt to make it more secure. Still same results,

try the hose10 mod and see if u like it
some people dont like the feel of it and revert back....
keep an eye on the boost gauge and dont hit over 16psi for now while you testing
hey will the mod work if i have a boost controller? i did it today and seemed like vod was worse and primary boost was worse, secondary feels about the same....
-
Did I do it wrong? I feel way less boost on primary and vod is way worse. I removed the piece off the T. Taped it and taped the BOV to manifold hose. What did I do wrong?

Why not just get an aftermarket ecu such as the eifil Prova etc.
Where would I find one of these?

The boost pressure will be different on both
turbos. The secondary boost pressure cannot be controlled directly. It is operated using a differential pressure sensor which allows a calculation based on the primary turbo
pressure. The secondary more or less free boosts but the amount of air allowed to pass into the secondary exhaust housing is metered using a separate valve. So it cannot be
controlled like a usual waste gate system.
The primary turbo's boost setting directly
alters the secondary boost pressure and
characteristics.this is the reply I got from subtech after they installed my mbc and upped the boost for me
-
Also what size hose do I need to buy to go from BOV to manifold for the hose 10 mod?
-
Is the secondary turbo boost controllable? Does hose 10 mod affect the secondary turbo too? I have a boost controller on my primary but a Subaru specialist told me that the se ondary is not controllable via controller and is basically in free boost

after remap - whatever the engine is happy with.
if its healthy sometimes 18/19 at high point
or even 20 then settles lower in high rpm..
all depends on the health of the engine
do basic things like service and perhaps a spark plug, also do an upper engine cleaner as well
replace your fuel pump and filter so you have good fuel flow
So pbms just advised me they don’t have ecutek for the older gen Subaru’s. Tunetechnic doesn’t work on twins, do I have any more options in Auckland or am I screwed?

easy to put a temp boost gauge
romraider should be accurate to within reason..
tee the boost gauge off the bov line and just run it to the cabin for testing
no need to hardwire it or do it too neatly for now while u testing
whats the most amount of boost id wana see? after remap and pre remap?

So with ref to my picture, i detach the hose with the blue outline and block that off, then connect the remaining 2 thats the horizontal part of the T?
IMG: (cuz i dont know how to attach it and my link isnt allowed to be attached for some reason).

any idea how much more power i'd get out of a remap with pbms?

I don’t have boost gauge on my car so I’ve been trying to use romraider to check manifold relative pressure but that’s probably inaccurate. Anyone around Auckland willing to help me install a mechanical boost gauge for cheap? Or are they fairy easy to install diy? I can’t do wires if that’s necessary though. Rom raiders telling me 13 on primary and like 18 on secondary but from the feel of it that’s probably not true might be something like 15-16 psi realistically

as above.. ecu swap needs to be accompanied with loom and some sensors and few other bits..
the rev c may be tuned on ecutek which is what they would potentially use.
if you are wanting some cheap gains then just the exhaust system makes for a decent pull
perhaps a zerosports sequential controller helps with VOD
some people dot the parallel turbo mod (hose 10 mod i believe its referred to) and up the boost a bit..
Thanks roughly how much power would I get out of a remap? Should I remove my manual boost controller and do the hose 10 mod? Does a mbc make both turbos boost the same psi or would it be ok for me to hose 10 mod with the mbc? Or no point and will cause extreme overboosting? Right now it feels like there isn’t the same peak boost from when I bought it stock compared to now which is a while later.

having a boost tap on these is a sure fire way to over boost the (very small) turbos. I'd remove the boost tap and do this.
The two turbos share the same wastegate, its a pretty complex setup. Many peopel refer to it as wizardry.
have a read through this:
Does a boost tap make both turbo run on the same psi?

If its 2001 I think you mean Rev-D in which case you are in luck. If its a Rev-C there is no remaping going to happen.
@Pappu1 Would be your best bet
What are my options if I have a rev. c ? Buy a replacement ecu and rewire it? I read you can’t reflash using open source software but u can do it using paid so idk maybe possumbourne can do it but 1200$ is rip
-
Dam mine is rev c, it’s be5c xxx no remap possible? Came over from the uk legacy forums and they told me it was possible rip

Yep
Just remove the tee-d off hose, put a straight pipe from mani to BOV (as per any other car), and from memory down at the inlet pipe there\'s a plastic T for the hose you removed and 10 to both join to the inlet pipe - just whip that out and put 10 straight onto the inlet instead
Can I do this mod/is there a point if I have a manual boost controller on the primary turbo?

Hi guys anyone know where to get an ecu remapped for a Subaru Legacy 2001 in Auckland area that’s not too expensive? I was quoted 1200+ GST. at possum Bourne Motorsport. They’re pretty good so I assume that’s why they charge so much. Wondering if there’s any cheaper place that’s decent, don’t really wana spend that much on a remap. Thanks

Solved, ty. Was a bolt misalignment issue so the connections between the pipes didnt sit flush causing a leak
