Question New Scooby Owner with questions

Hi everyone I just got my my00 2.5 RS on 5/30. I am already ready to start modifying it. (gotta love the bug). I am thinking about putting a weapon R intake on it and putting a Aerospeed muffler on it along with underdrive pulleys. I am also going to be putting a 18mm sway bar on it. I was thinking about doing the silencer removal on it....but does it give any kind of bhp boost??? or does it just help the sound??

The silencer removal (the one from the fender) is a mute point with the MY00, it's already gone.

I'm still waiting for word on whether intake mods on the MY00 really do cause rich-run conditions (as some have claimed) before I go replacing my stock system with anything from the aftermarket. But the underdrive pulley, sway bar and exhaust sound like safe bets to get you started.

There still is a silencer on the MY00, its a large "reservoir"(sp?) just slightly behind the passengers headlight and just above the ABS unit. I think it takes two bolts and about 7 minutes to remove. And then an ecu reset. No hp increase, but it gives a good sound at WOT above about 3500rpm.

Hey 8Complex,

Something you said in this thread has me somewhat concerned. Do you know of anybody that has sucked water into their engine taking air in from the inner fender? I'm asking because I just did Larry Ganz's ( ImprezaRS.com ) intake mod and I sure don't want to hydrolock my engine. I e-mailed Larry and we both agree that the inner fender is well protected from water entry. I am pulling air in from the upper level of the inner fender and not down near the scoop in the bumper. If you have heard about anyone getting water in the intake from the inner fender I'd sure like to know about it.

Thanks!!!

Yeah 8,

Like I told PunkRS, Mike Jerry in Denver is actually running a '99 turbo with a foil-like "clothes dryer vent" hose running from his front bumper opening, passing through the inner fender and directly connected into the intake. He drives it rain or shine without water getting in the engine.

My intake doesn't even have a direct connection to the orange vent in the front bumper like Mike's, and should be even safer from water entry (although not totally immune).

Well I managed to get water up into mine when I had it in the fender... It was about 1-2" into the fender at the rear hole and I hit a good puddle and managed to suck up some water. Fortunately it just soaked the filter instead of killing the car. Whew, close call.

Yeah, the Weapon*R intake sucks. The filter is supposed to filter horribly and the tube... well it just looks like a bad design to begin with.

There are quite a few solutions with the MY00's for intake that are very cheap. Most involve leaving the stock air box and removing the rest of the intake plastics. Most of those run a flexible tube to the fenderwell to suck in cold air as well, though you have to be careful for sucking up water instead.

the K&N is now avaiable for the 2000 (supposedly)so skip the weapon r save the $$ and replace the re92s. push the sway bar up higher on your list it make the car way more fun (although i really didn't notice it until i got on the dirt)

BTW just for clarity, the puddle I hit was almost a pond... probably 8-9" deep and 30-40' long. I didn't realize that the corner there dipped down so much and I was just going to splash around and that happened... whoops. I kept it revving until the filter dryed out somewhat and then parked it at work. When I came out 8 hours later it was all dry and running normally again.

I got real lucky.

Hey 8,

By the sound of your encounter with the "pond" it sounds like you might have even sucked in some water even with the stock intake. On my MY00 the stock intake is right below the top of the headlight and faces downward. It seems fairly exposed to water that would splash up and into the engine compartment from the bottom if you hit a large enough puddle or pond. I guess the water entering the stock intake would probably settle into the large plastic resonator box instead of going straight to the air filter/throttle body as it would with a modified intake system. I appreciate the thoughts as I sure don't want water in my engine. I assume you hadn't modified the bumper air inlets or the inner or outer fender before this happened?

thanks

Question

I thought someone on here had sucked in water from a bumper-vent hose and actually hydrolocked their motor. I remember something about 3 bent and 1 broken rod!?!?!
Anyone??

Scoober,

I could definitely see water getting into the engine if you ran a cold air intake from the bumper vent. It just makes sense as there would be a direct path from the bumper vent which can easily come in contact with water. It basically scooped up water and force fed it to the engine! I am more concerned about water reaching toward the top of the inner fender where the two large holes are. This is where my cold air inlet is located. I have discussed this with Larry Ganz since I am using his trick cold air intake system, and we don't think it would be too likely that a lot of water could enter this area unless you drove through a lake. The fender seems pretty well sealed off by the bumper and the inner wheel skirt. I can see water coming in through the bumper vents, but not a lot unless you removed or modified them so that the openings are larger. Again, I just want to see what problems others have had so we don't get the dreaded H2O!

Thanks

Contrary to other peoples opinion, i have the Weapon R and love it. OK, so Brucelee and 8Complex are right in the quality of VR2 filter, its a piece of $h!t!! But the piping is quality and the performance kicks a$$!! Just install that intake, run an extension from the filter through the fender and down to the vent of the front bumper, open up your hood scoop and side vents and youll be drawing in plenty of fresh cool air and lovin it. Not to mention the sound at WOT!!! I tried about every other mod with the stock set up and didnt get any where near the performance.

Talking

You should probably wait until you've broken in the engine first. You really need to wait until you have at least 1000 miles on the engine before you rev it past 4000 rpm, and do any kind of harsh acceleration. I can assure you it would be all too tempting with mods on a brand new car to open it up and push the car to its limits, when it really isn't a good idea to do that yet.

You can suck in water with the stock 00 intake. I did it

I knew it sucked up water because when I took the intake apart, there were water spots all along the tract and inside the plenum on the back of the throttle body. No adverse affects however. I dont think it got past the filter luckily.

Sad to hear that the Weapon R intake sucks. What's a good intake then? I'm on group buy for JC's intake for my 98RS. Is this a good choice.

I'm highly dependent on you guys for the first word on whether a product is good or not. Thanks a bunch really!!!

what's more important ?

being able to drive well and safely at any speed or sounding like you've got 100 more horses under the bonnet (sorry - hood) ?

That's the way i look at it.. so, as I start to improve my MY99 special edition I'm going:
first wheels / tyres for better grip, cornering stability and steering responce / turn-in:
17" wheels (OZ-PRODRIVE, from the new UK P1)
Bridgestone S-02 PP tyres
and you need to stop, aslo:
Brakes. TAROX 6-grooved + drilled 294mm (standard diam. - because they're already homolgated here in Switzerland) with FERODO DS-2000 pads

Then after you got used to this - you need to be able go even faster and be more stable and still be confident and safe, so uprate the suspension
Fit the best. Eibach springs & Bilstein dampers.

Then, after you reach the (sensible) limit on handling... think about the engine.

Phase 1 tuning (full ECU re-map, exhaust, remove 1 cat, air filter) - good for 260 bhp and 280 lb.ft torque.

Don't increase the power until the chassis and brakes (and you !) can take it.

Air filter & exhaust will just improve the sound and maybe give you a few bhp top end and few lb.ft torgue midrange. So what ? if the car is still on standard suspension & wheels / tyres.

Isn't it better to improve the handling, responsiveness and safety at all speeds before adding to what is already a lot of power ? I think so.

..and having said that, I just rembered that you guys don't have the turbo over there, so you're almost 60 bhp behind what we have straight out of the showroom.

Check out the Power Engineering site in UK and the Scoobynet site for power curves http://www.scoobynet.co.uk

(the PRODRIVE / STi quickshift is a smart move also)

Swiss Steve, power may not be a big deal to someone who already has 200-odd stock HP with the 2 liter turbo...

But the Impreza 2.5RS is underpowered. Not heavily, but it is. Getting 200 hp out of it without going turbo is the goal of most daily drivers and that's why you see so many people looking at intakes and exhausts.

Just my 2 cents.

Overtime, and all you other Scooby-lovers...

wasn't meaning to 'rub your noses in it' !!! as I said - I only realised half way through my ranting

I realise it's a big challenge trying to squeeze more out of the (non turbo) flat four lump... it's something I ponder from time to time as I work for a US company here in Europe and there's a good chance I come over there for a year or two... so - what would I buy if I did ? (Certainly not any Detroit (scrap) iron - that's as sure as mustard !!

TELL ME - why is the turbo NOT available over there ? is it just SUBARU marketing or is there a genuine technical (emissions) reason ?
Are there any companies that do imports ?
(How else did that 22B get over there ?)
I have a mate in Geneva with a Mitsubishi EVO VI - that would be another cool one...?

You're lucky in one way - you're the only ones (except Japan) where the two door is offically avaiable.
(What would you rather have - two less doors or 50 more bhp ?!!)

Sorry, gotta place my vote to the Coupe... I can stragle and scrap to get the 50 Bhp, hell even swap engines if the budget is there... But you just can't start with a 4-Door and change up to a Coupe...
