Thats good to hear, glad it worked out for you ;D

Planning to do a replacement on mine too, any tips/instructions on how to get it done?
Cheers1)Be patient ;D
2)Leave the clamps clamping the silicone onto the actual intercooler loose so you can move the silicone round until everything is fitting right, then tighten. Especially the pipe leading to the primary side turbo. This avoids having to take the intercooler off if you tighten them up, then try and fit the intercooler back on, only to find that the don\'t quite line up with the turbos ( I found this out the hard way
)3)Measure twice, cut once.
These were the things I found when putting them on my car.
Only took me maybe 30mins to do, but ive attacked that intercooler many times before.
-
Yeah the turbo outlets are ridiculously small - to be blunt I had to punish the silicon a bit to clamp it down, that said it\'s got a lip on it and I was literally trying to rip it off to make sure it wouldn\'t blow off under pressure. I\'m comfortable with it for a DIY job but if a workshop charged me for it I\'d spew haha. You could make it work fine with a reducer of course but not much room in there to get things done up.
Option B of course is to spend $200 on the made to fit stuff from ebay so your call there
Tossing up now if it\'d be worthwhile getting a V7 sti cooler on there as well
Here is a bit of information I came across a while ago in regards to how good different Subaru intercoolers are. Might make a good read considering what your thinking of doing ;D

Yep, hence why I reckon if you could find a silicone pipe that reduces in size, it would be easier to install / not put so much strain on the silicone
-
These are the ones I got, seemed to do the trick and they also come in blue if you are that way inclined. Looking at the ones you put up and these, seem to be the same just different sizing, pricing and colour haha.
http://www.trademe.co.nz/motors/car-parts-accessories/performance/turbos/auction-522703259.htm - 90 degree bend @ 1.75"
http://www.trademe.co.nz/motors/car-parts-accessories/performance/turbos/auction-523621557.htm - 45 degree bend @ 1.75"
Both require a wee-bit of cutting to the right size in order to fit, but they worked fine on my car.
If I was going to do this again, I would try and find a pipe that had 1.75" ( internal diameter ) on one end, reducing down to like 1.5" or 1.25", because the outlet from both the turbos is quite a-lot smaller then what connects to the inter-cooler. Don\'t worry if you can\'t, you can still get away with these, it just requires a little bit more tightening to get the silicone to fit on the turbo outlets, or you could get creative and make a spacer, up to you.
**note**
I purchased the particular brand because I couldn\'t find any other traders that advertised the correct size. Looking at the other products on trademe, there are better ones / more proven brands with higher tolerances, so you could try asking those traders if they could supply you with the sizes, but I figured that the little twin turbo turbos weren\'t going to be maxing those tolerances anytime soon, so I am happy with the ones I have, lol. If the other traders could supply you with the correct sizes, it might be like a $30-$40 difference, but it is completely up to you which brand you go with.

It won\'t be any faster - it\'s still the same turbos, running the same boost, just rather than one coming on then VOD and re-spooling it\'s just like one turbo which is far too large
Just "different" - I\'d do it if I was taking it to the drags or a trackday or something for sure, went back to normal last night and helloooo low down power again... and hello VOD again you suck
Ended up going back to normal again as well. Your right, track drags, etc it would be great, but around town you really miss the low down lol
-
Feels faster, but that could be to do with the lack of power before so it could have a kind of placebo effect. It\'s like driving a little car with a big turbo, nothing, then all of a sudden heaps. Still when it gets going it brings a smile, lol

Just fitted new intercooler, sorry interwarmer pipes the same as Marky did, really does fell like it made a difference. Car feels like it spools earlier, but it also seems to not have to strain so much especially in the lower RPM range before it finally starts to boogy. Those standard pipes are sooo small!
All for under $40
Verdict: Do it.
Thanks for the sizes Marky, they worked perfectly. ;D
-
Gave it a try, is a completely different car after the change. Your right, it really does feel like an N/A until 3.5-4k, lol.
-
So if I were to replace them, which model Subaru would be best suited to take them off?
-
Really? Engine mounts, never thought of that. Are the leads quite a common problem with the older RS subbies?
-
I've got a really similar problem with my 93 RS liberty. It works fine part throttle, then when you give it the beans it will start to studder and surge really bad around 3500rpm and continue until you let off the gas. It's completely standard. Any ideas?
-
Had a very similar problem with my car when I first got it.
Tried almost everything on the damn thing but turned out to be the black box of Satan had just packed a sad, replaced that and it runs mint now and has been for the last two years.

Sounds wicked man.
So is it quite a noticeable difference? When does the primary spool up now?
Wouldn't be able to flick some pictures up of your beast would ya

with my B4 2002, I have just had a turbo upgrade with the primary to a TD04 with rage pipes and full exhast and it is real quick now.Masssive change in power. No reprogramming has been done yet tho so only running 10psi boost but still runs great. Sounds awesome to. Cost were $2000 . Highly recommend .
What did you have to modify to get the TD04 in? Sounds like its worth having a look into

Niiiiiice leggy man!

From Wikipedia
The fourth revision of the third-generation Legacy, introduced during 2001, made several important but subtle changes to the front of the car. The fenders, grille, and headlights were altered slightly, making interchangeability with Rev1-c impossible. The headlights in the Japanese market were of the HID variety, and were slightly smaller, while the grille also shrank slightly. The HID headlights had a dashboard mounted adjustment switch that allowed the driver to re-aim the headlights to reduce glare to approaching traffic. The bonnet also became a lighter alloy, similar to that available on the STI's at the time. Compression and timing changed in order to further reduce the effect of loss of boost during the switch over from the primary to secondary stages. The ECU also got an upgrade, it is now tunable by the manufacturer or third party tuning workshops.
Hope this helps

Cant use V7 hubs on rear.
Unless you get custom made hubs to suit.
Easy way is to use adaptors and use standard rear rotors.
Brembo rear Rotors have 190mm dia handbrake drum while B4 is around 170mm.
Another way is to cut n weld the backing plate.
Do a search as ive cut n paste a complete thread from an old member reguarding this conversion.
Sweet, found it. That is pretty much exactly what I was after.
Thanks for that

I just did a little google'n about it, and this is what i found.

Haha, I have seriously considered it! After reading through Gazzy2000's thread just makes me want to do it more. Never know, might have a new build thread soon enough, lol. :
Cheers
