Good to know. When I start up the engine tomorrow morning after sitting out all night, I'll see if it happens with AC off. Hadn't been paying attention to that, didn't think they were related at all.

Do you have same engine/tranny as me?

I have a '12 Impreza, which is the same engine, but I have the 5 speed. The air conditioner cycles on and off.

Experiencing a weird issue with my '14 XV Crosstrek. I have Gas/CVT. 7.4k Miles.

I've noticed 3 issues involving (I believe) the CVT:

1. When I go in to Drive from Park, and push the gas, it takes a half of a second to respond, resulting in a "jerk" forward, as the engine revs but the transmission hasn't caught yet. Kind of like if you go in to neutral, rev the engine, and then switch to Drive while it's revving.

2. When I sit idle, especially right when the car starts, whether braking or in park, the car sits at around 900 RPM and occasionally (maybe once every 30 seconds), jumps to around 1100 RPM, then slowly works it's way back down to 700-900 RPM. When it does this, I hear a "rumbling" from the engine, almost the same as if I stalled out a manual car but not quite as severe.

3. When I'm driving and speed up, and then let go of the gas and coast for a bit, as my speed decreases I experience similar symptoms, such as jerking as if I'm going from a really high gear to a low gear in a manual and buck a little (except, much less severe). This is the least noticable/annoying of my 3 issues.

Are these normal for this car? They honestly don't bother me that much, I am just curious if they are normal or if what I'm experiencing needs to be looked at. I will probably mention it at my next oil change unless someone says my car is about to explode.

#1 is probably due to the way a CVT works. It's just something you have to get used to.

#2 Sounds like AC is cycling on and off.

#3 same as #1

Also, cars will constantly try for a lower idle RPM. They'll drop and drop while sitting there until they knock, then they'll raise it a not. As temperature changes, they'll continuously try.

Hey all,

Thanks for the advice/responses. I've confirmed it's definitely the AC compressor cycling with #2. I think #1 and #3 are as you all said...just how the CVT works. I had my boss drive it (who also has a CVT subie) and he didn't recognize anything unusual either.

I'll have my dealership take a look when I'm there for my next oil change, but it all seems good.

My CVT Altima does the same thing when shifting from reverse to drive. It seems more pronounced when the engine is cold. It's probably just how CVTs work.

The WRX hatch I purchased in February is just shy of hitting 12k miles, so I figured it was finally time to order an AP with turboback exhaust. Once it gets here I'll need to find a good shop in the bay area to dyno tune, since I have little faith in generic maps. Anyone have suggestions on tuners?

Also at least from any 12 onwards manual or cvt they will rev higher in neutral until the engine heats up and then back off when the blue light goes off.

PZEV is great. In the summer you'll start off revving around 1400, but in the winter you'll be well over 2000.

Blue light is around 120 F I believe.

My brakes on my STi have been squeeking like crazy for the last month, and getting worse. So I ordered some stoptechs figuring after 20k miles and liberal use of the brake pedal, the OEM pads may need replacement. 20k miles isn't a lot, but the noise...

I just got done swapping them out, and the OEM pads still had nearly half their life left. :wtc:

Are the OEM pads really this loud or is there some other cause? The new pads are whisper quiet, of course.


Also: When just swapping pads, should I bother bleeding the line? The pedal feels fine, but I only drove it around enough to break them in per the manuals instructions. I never bothered on my WRX or Civic.

edit: Also this is my first time swapping pads on a Brembo, amazingly simple.

You only need to bleed if you opened up the hydraulic system ( i.e. brake lines, master cylinder etc). Swapping pads should not introduce air into the system so you should be OK.

Yeah I purchased everything from rallysportdirect, they ship quickly to me and no tax is quite nice. Should be here on Monday.

My buddy had a 2010 wrx that he had stage 2 but only with a generic tune, and it was pretty quick. Curious to see how much better a real tune will be. He has a stock 2013 now so I'm sure he'll be wanting to upgrade after he sees my car. ;) I'll send him your way if so.

However, do keep an eye on the level and make sure it doesn't overflow when you push the pistons in.

I've got a clicking coming from one of my right-side vents. I think it's the right center console one, but I haven't moved around in the car enough to be sure. I assume it's the fan, how much of a pain in the rear end is it to get in there?

Not too hard to get at, and the part is cheap too on RockAuto (it's a VDO part shared with its contemporary Sentra). You can pull it right out from the bottom without even having to remove the glovebox on the older cars. Just have a peer up there.

Mine ticked for nearly 2 years and didn't die, so chances are if you pull it and remove whatever foreign object is stuck in it, the clicking will stop. They're tough bastards.

Lowered the tire pressure set by the previous owner and it's fixed almost all of the horrible shudder/chatter I was getting when moving from a stop.

Tires were 8lbs too high in the rear and 6 in the front.

Two questions for the '15 WRX owners (well, or anyone that knows):
1. Does the 2015 manual WRX have SI Drive and if so where? Google is failing me and while I know the CVT has it, I think maybe the manual doesn't? Or at least I don't see that stupid center console knob :)
2. Where is the best place to lurk and watch people modding their 2015s? I can't seem to figure out which forum everyone is going to...

What kind of modding? Chassis-wise the car is very similar to the old model. Engine is different but some of the same things are still popular like an exhaust, intake, and tune. Only with this car there's no up-pipe because the turbo sits right on the exhaust manifold in front of the oil pan. Not sure what is available for them (downpipes and exhausts are), or what is compatible between the LGT that already exists.

I've noticed since I put the new wheels on, there's a clicking coming from the passenger front side when I take off. I thought it might have been the glue on weights they used to balance the wheel, but they don't feel like they could be causing an issue when I try move them. My friend said bushings, which could make sense I guess, the car's 10 years old in a few months, but would worn bushings make a clicking like that? If it is bushings, I can just get a Jamal approved kit and press them in with a vice right?

E: And what would you guys recommend I buy to replace worn wheel bearings because I'm fairly sure they are gone too, unless the wheel bearings are causing the clicking? How big a job is it to replace those myself? My last exam is on the 20th of November, I want to go away on the 24th, could I reasonably do it in those 4 days on top of packing for a week camping trip?


It's done nearly ~190kms/120k miles

Well my luck only ran so far, as I have to return to GST tonight after a database glitch with the dyno, so I'm running the OTS map until then.

Pretty happy with the setup so far though, and I appreciate the recommendation, they are a nice bunch of people to do business with. Can't wait to drive it with a real tune.

Brake question!

On the rally car, being 5x114.3 hub and using 4/2 pots, I have to use custom rotors on the front (DBA, say). For rears, I thought I've heard about turning down stock brembo rears - is this possible?

Also, coincidentally, is there a rebuild kit for rear 2-pots that include pistons? My brake pads might've escaped and the pistons might've been braking directly on the rotor. Maybe.

Running without a tire is rough on a car.

jamal
Apr 15, 2003

No the brembo rotor is wider and I don't know how well turning it down would work. In addition to the dba parts there is also an OEM rotor that works, but it's a group N part, so probably more expensive.

Rebuild kit only comes with seals, but I'm pretty sure you can order the pistons on their own too. Possibly from stoptech/centric too. I'll look up some things.

So DBA it is. I'm looking at about $500 for all four corners for DBA, so not bad.

Also the knuckle sheared at the trailing arm mount, so I need to replace that which brings me to another question. My drivetrain setup is from an 06 STi with a 3.54(?) rear R180.

My buddy is selling an entire 02 JDM STi rear setup for $500. R180 (3.9), axles, knuckles and hubs.

A) I know the R180 wont work, but will the axles work?

B) Can I swap out the knuckles and change out the hubs?

jamal
Apr 15, 2003

Yeah as long as it's from an R180 car the axles and uprights will work, regardless of the bolt pattern.

Yes. The rear r180 5x100 bearings are the same as 5x114. The fronts are bolt pattern specific though.

Ok awesome - so it looks like other than the hubs and actual R180, the rest can be used as spares. That's good news.

I wonder how hard it would be to change my 1:1.1 to a 1:1 so I can use 3.9 R180's..

I think you would just need the transfer gears from whatever 6-speed car has them. With the tailhousing off they slide right out. The extra rear bias might be a nice thing though.

My 2007 STI needs front (and possibly rear) brake pads. The Stoptech Street Performance line seem to get good reviews and are cheap on Amazon - how are they?

My usage is daily driving about 1,000 miles of back roads a month plus the odd autocross.
