Dropped in a group N transmission mount, after a test drive I wish it had come with it from new.

It will probably be one of the output shaft bearings. Is it louder when decelerating?
-
OH HAI I should organise a meet sometime, however today is not that day
-
I never got whine from my DCCD that was worn. I did get a lot of whine from the gearbox bearing wear. But that also has the gear shifter move when you accelerate hard or lift off at higher rpm.
-
Actually, I misread the original question. I'm not sure exactly what fluid the center diff takes; whether it shares it with the gearbox or what. Presumably yours is DCCD which also complicates things.
-
The whine gets loud around 2.5k rpm in second, 3k rpm third gear and so on. I have seen videos and talked to a mechanic on the topic. Either way no harm in doing a change and starting there. I might try get a video of it at some stage

Castrol Syntrax 75w90. What makes you say it's the centre diff though?

Pez Crean started following 6 Speed centre Diff whine

Hey everyone I own a 03 STi that has a centre diff whine, I’m going to do an oil change ect to hopefully stop that before digging deep into my saving to do a replacement. What oil do you’s recommend? thanks a lot 🙏

Hi folks from Canada's East Coast! I have a 99 B4 EJ208 TT that I've been tinkering on for past 9 years and I'm having an issue with my secondary turbo leaking oil out both ends into compressor snail and downpipe/ECV. 2nd turbo is a VF26 CHRA with VF27 exhaust and compressor housings, so it's journal bearing type. The banjo bolt is identical to the one in the primary VF26 turbo, so oil flow should be the same. No restrictors that I've seen, but I've heard they're usually in line for the VF27 BB turbos. The stock VF27 was leaking oil too before swapping it out for the VF26 CHRA. Both turbos have fresh rebuild kits with primary being completely dry, yet 2nd leaks like mad. I'm almost positive the ECV is collecting oil because I get a bit plume of blue gray smoke when I spool 2nd turbo and the up pipe is oil soaked (maybe coming out through the ECV flap linkage. My current thought is over pressure inside the turbo CHRA which is pushing oil out through the seals (small piston ring type). Cause is either too much oil flow or poor drainage. I have a dual oil catch can setup that I've confirmed has good flow out of the crankcase and head breathers. And I'm positive I haven't overfilled the oil pan so it shouldn't be an issue of oil not draining due to crankcase gases flowing up the drain line. For oil supply, there is no restrictor, which I think is proper for a journal bearing turbo. Mind you the stock VF27 didn't have a restrictor either. Kinda stumped on why its leaking. Anyone have any advice? Related Mod List: Killer B oil pickup and windage tray Ebay Silicon TT inlet DIY dual oil catch can setup (PCV valve clean and floating proper)

Having seen a few shatter off the centre I get super paranoid about my plastic ones, not quite paranoid to spend the big bucks on RCM metal versions just yet but one day

Hi everyone, wondering if anyone has put metal cam gears on a bh5 legacy. My tool always seems to chip them a little taking them off, and I didn't have a spare for this one https://imgur.com/a/lS69GA4 Doubt it could actually cause much damage running them like this, however it always sits in the back of my mind ? I think that 2nd and 1st gen have metal ones? any luck running them? cheers

So wait, it will build boost if you freeboost it? If so it's a problem with your boost control, but you want to be very very sure it's not in limp mode and restricting boost because of that.
-
Definitely sort that exhaust leak mate - all the exhaust gas that should be spooling your turbo is exiting out that leak before it makes it to the turbo so that will likely be your main issue (if not all of it).

you're all old NOW hah no h8 Hi

I was just reminiscing and thought I'd login to say hi. So uh, hi ?

In need of some advice I have a 97 stb sf5 that was running mint now won’t build more then wastegate pressure unless free boosting and seems to run like s*** when boost solenoid is all hooked up , iv also noticed my bov isn’t opening anymore (can push it open with finger ) and even blocking bov off still hear no turbo flutter anyone got any advice in what to start looking at ? it does have a exhaust leak between manifold and up pipe but I wouldn’t of thought that would cause that much of a drastic change?

Nice, BRZ caged?

So I thought my next car would def be an EV/hybrid, but I guess I couldn't do it.. Picked her up this week. Yeah you cannot order any 6Spd manual WRX from Subaru anymore.. Luckily they had this one.

from factory STI wheels sit slightly inside the guards; Evo wheels being the same 18x8.5 but +38 means they will sit more flush with the guards. It’s basically almost the same as running a 15mm spacers with factory wheels of which I know of a couple people doing that with no issues (I plan on running 15mm all around with factory wheels as well).
