I will be interested in hearing how the intake air mod goes on your 00 OB as I was considering the same on my 00 GT. Take a look at the underside of your hood where it overlaps the front of the scoop. There is a plastic flap on the hood that appears to nearly block the scoop opening when the hood is closed. Could this be to keep rain from entering when at speed? If so it seems it would also block most of the air.

No real noise gain or power either with snorkus removed. Haven't yet simply run some tubing from the filter box to the hole in the sidewall.

I think Craig's resonance frequency explanation describes why my set up doesn't have the humming you mention. The 6" intake hose I have running from the airbox to just inside the fender area must be preventing that resonance.
Try it -- a flexible intake hose at a local Pep Boys will cost like $7.
Ken
Ken: what diameter tubing did you use?
Zoom: can't say much about the mirror, but Subaru is supposed to come out with a moonroof deflector soon, and it should install easily with two bolts, like the other models'.
Stick with OE bras for a good, supportive fit (images of lingerie popping in my head...focus!).
I'd order both from Darlene. E-mail her to get price quotes.
We should call that flap a "bug blocker".

I believe I used a 3" diameter flexible intake hose. Don't remember the brand, but I think they're pretty ubiquitous. The hose was about 1ft. long so I cut it in half and pulled it through the opening in the bottom of the airbox into the fender space.
Ken
There is a bolt just in front of the air box, did you use that?
-juice
Basically, it just kind of curves out of the airbox into the fender well. The hose is made of this soft nylon-like material supported by a wire coil inside so it doesn't move around very much. Also, the 6" length I cut is short enough that it doesn't droop.
I also didn't need to secure it in any way to the fender or airbox. I initially thought I might have to, but the hose is fairly snug in the opening between the airbox and fender. Also, the hose has metal clamps on both ends that are slightly larger than the hole leading into the air box. If you "thread" the intake tubing (cut off end first) from the airbox into the fender, the clamp prevents it from going in any further.
I've checked the hose several times now (after boucing off the rev limiter several times :-) )and it seems secure.
I'll try and take photos this weekend and update my website.
Ken
Now I'm curious as to what that tubing looks like. Is it black plastic, basically?
-juice
Yep, it's a black nylon-like material. Softer and more flexible than plastic. They have a wire that coils through it to give it shape.
You can find these things in any auto store. If you want, I can send you the other half that I didn't use.

I see 0-60 times for the 2.2l of something like 10 secs. That is not going to cut it. Rallispec says intake and exhaust will improve this. SPD says no, nothing but forced induction or cams will. So am I screwed on acceleration on this car if I go the Impreza route? Or should I take the money of the car+mods and get a 318Ti Hatch? It has 138 hp, less than the Impreza, yet makes 60 in 7.8.
why oh why isn't there a 2.5 wagon
I agree with Rallispec, intake and exhaust will help. Ask Ramon how much; he has an OBS too. Cams would help even more, but no one has figured out of the Cobb Tuning EJ25 SOHC cams are compatible with the EJ22 SOHC. The heads themselves look the same from the manuals I've got, but that's a long ways from fitting and testing the cams.
-Colin
Lucien: scratch the Prelude if you need to carry any stuff -- the trunk opening is like a mail slot!
Craig
Don't trust edmund's stupid 0-60 as they rate an RS doing 8.2 or something.
Anyhow with my intake (similar to colins), exhaust (similar to colins), pulley (colin copied me!) I am able to hit that 8 ticks. You just let 'er go at 4000rpm-4500rpm. Easy. I wil do another one in the next few weeks with this err....Gcube device that's used in autoX circles. hehehe... stock form I did 9s. Autos are slower too. Shh.... don't tell the autos or they'll kill me.
Wait for SEMA. The Focus (and PT Cruiser) are supposed to gets LOTS of attention. See what they have to offer.
No more FWD for me, though.
For Soobs, keep in mind most models need 3rd gear to hit 60, and that 2nd shift costs 0.4s or so. So the numbers don't look at good as they feel, nor do they necessarily mean a slower car on the track.
OK, Loosh, first one of us to hit Track Auto or Pep Boys picks up that tubing. We'll split the cost.
-juice
So did you get a chance to try the intake hose mod above?

So after work I decided to drive slowly (part throttle) to my Sunoco station and fill it with 94 octane gas. It's running fine now. Even with 5000rpm WOT.
Now what am I to do long term? I don't want to keep using 94 or even 92 octane. I dunno. I much prefer 89. But Colin sometimes I like to let 'er rip and go nuts. Those would be the times when I fear it might detonate or worse blow up a piston or 2... or all of it. =( I think I might use 91 octane and see what happens.
I don't want to get an AFC...cus I don't even modify my engine as much as Colin with cams! So no need to go all out yet. How?
Anyway, I'd like to replace it with an enhanced version if possible. The original was too low and too hard for my tastes. Does anyone have a recommended replacement. Ideally it would have a slide out or flip down cup holder and match the charcoal gray interior.
Thanks,
Bruno (96 Legacy OB)
Bruno: e-mail Darlene if you want an OE replacement. Alternately, she sells arm rests for all other Soob models, so if you see one that might fit give that a shot.
The Forester has an armrest extension, same gray, but no cup holder.

- Mobil 1 synth for engine oil.
- Scooby Doo riding shotgun
I dunno. I'm sure I've missed out a few. Some DIY stuff here and there.
What do you think of the Redline fluids? Did you drain the stock fluids and then use one of those pumps to refill?
I've seen the diffy drain plug and fill hole on the back side. That looks easy enough.
On the tranny, are there are two drain plugs? Was it easy to find/do? You wouldn't happen to have any photos?
-juice
Now, I know what a resonator is -- it's just a chamber or tube that vibrates with sound waves and either attentuates or amplifies them, like a guitar cavity -- but what's a torque chamber?
Craig
Juice : the redline fluids are nice. I just added more to the tranny cus it drank up quite a bit over the months. What sux tho is that you need a long pipe to fill the tranny box. No photos.
IIRC, the drain hole for the tranny is a PITA! It is located right above the header (passsenger side) and it drips some to the header plates. Sux! So I guess if you sorta have a way to re route the drainage say with a cone pipe to direct it away from the header that would be nice. Now I am not sure how your Forester header is like. It could be better angled. It's been almost a year since the switch to Redline. All I can say is that in witner times the shifting is still as slick and nice as it was in the summer. I won't be changing it for another year.
The Phase I also has an intake plenum also located right before the throttle body. It is indeed smaller than the Phase II plenum.
Ken
The first place I saw of this type of intake manifold design was on the 1992 Corvette's LT1. I don't know how long Subaru has used it.
So anyway, I am very suspicious of any aftermarket intakes that replace the torque box with a silcone elbow and a cone air filter, then claim there is no loss of low-end torque.
-Colin
However on some Imprezas, the plenum has an air filter in it. What you can do (which I did) is to replace the air filter in the plenum with a Subaru plenum gasket. I picked mine up fopr 50CDN loonies. That minimized some obstruction. However becareful when you do the replacement as you can easily mis align the plenum box thus causing air leak which is bad. Your car will rev roughly and go bonkers upon acceleration. Speaking of experience.
Craig
How can you tell which engines have that 2nd filter? Was that just the 2.2l models?

I gutted mine instead of using the gasket. I had to silicone it back into place though, since the gutted filter is very flimsy. In short, buying the gasket from Darlene is probably smart.
-Colin
I know that's not a word, Mike, you don't have to look it up!
Look at these fluid change instructions:
http://miata.net/garage/trans/index.htm
Amazing. Great detail, photos, the works.
ramon: looking at those, was the Soob similar?
-juice
Juice : I'm afraid to tell you that due to our 2 to 1 header Y headers, I don't think it look the same as the Miata's at all. Their's is so easy looking. You defintely need a looooonnng nose cone to fill your car tranny up. =(
Miata clubs are very organised. What can you do as there's like 500,000 of them to date since it's introduction back in 89? That's prolly more than the entire fleet of Subaru from 89 onwards!
Colin : Apparently some Imprezas have them. I found out later that some other 99s don't! Well it's ok. It doesn't void the warranty as the gasket was designed to take up that spot anyways. In fact since I screw up with the alignment of the eplenum box, my Scoob mechanic came to my rescue. He didn't charge me. What a nice guy. I'm gonna miss my dealership here in London, Ont. once I move back to Toronto. I think if I were to buy a new Subaru again, I'd drive all the way back to London. Just to give them my bidness. Their service so far is top notch. Even when I messed up my TPS. hehehehe.... that's another story for another day.
1 '01 Impreza Wagon, purchased as close as possible to the release of the New Age model
1 Rallispec cold air intake

4 RS wheels and some kind of tire, or tasteful aftermarket wheel 16"
4 H&R/KYB spring strut combo, or like.
1 big brake kit up front. Move stocks discs to rear.
1 20mm sway bar in back.
Things like upgraded seats, CD player, yadda yadda as budget permits.
What do you think??
You guys think the '98 Foresters have that 2nd filter? Any thoughts?
Loosh: sounds like a plan. You'll really shock people, 'cause your ride will be very stealthy. You also won't get the speeding tickets you would in a WRX.
-juice
I don't think the Phase I has the 2nd filter. I've never come across someone mentioning it.
