They're the same between the wrx/sti, usdm/jdm.

something doesnt sound right...double check the alternator belt part number and/or ensure the lock nut for the tensioner adjustment bolt is fully loosened before you raise the alternator up to get the full adjustment range.

i know 100% that the adjustment on the alternator is maxxed out. the long screw has no more thread at the top for it to go. i bottom out on the bracket basically...

old alternator belt was maybe 1/2- 3/4 of the way up the adjustment screw. this one goes all the way up to the top of the bracket and has no where else to go...

i also called the part store to see if the part number for 05 wrx was the same as 04 sti and 05 sti... they all show that it used the same belt.

How much slack is in the belt when the tensioner is maxed out? I had issues with aftermarket belts on my engine too.

With the aftermarket belt and the adjustment maxxed, the belt wasn't loose enough to fall off, but it was loose enough to slip. After 4 or 5 different belt sizes/belt manufacturers, I went OEM and it fit like a glove.

Then why don't you take the old belt with you to the parts store and have them match the size??

that's exactly what happen to me....

i ended up going to Subaru and bought the belt that was recommended by IAP and it fits perfectly.

also notice that the belt has a pk number on it, oem Subaru was different then the aftermarket dayco.

Could be supplied by Bando, an OEM supplier, they have a #pk, part number reference where # is the number of ribs. I've had good luck with them and Goodyear gatorbacks when i replace my alt/powersteering belts.

ya.. the number on the dayco belt was 5pk0890. the oem Subaru belt was 5pkxxxx.. i forgot the numbers but they were different. so it may be a different belt or maybe just a fluke... either way the oem is the way to go...

now all i need to do is find out if the 207 camshaft sensor is the same as usdm.

also to respond to Ryan, i wish i could take the belt and go to the store but i would need to take it off at the parts store so i can drive the car. didn't feel like putting it all back together and then taking it apart in their parking lot.

ej207 Front Cam Position Sensor = same as US ej205 WRX 2002-2005
ej207 Rear Cam Position Sensors (2 of them) = specific to Japan, we carry them in stock in Colorado. Click here for more info

Belt length - Run a piece of string around the belt, then measure the string with a tape measure. Bingo, you then will know the belt length +/- 0.25"

damn that doesn't help... how do i know if it is the front or rear??? i have a fault code- p0340 which shows the camshaft sensor circuit... but it doesn't say what sensor. all the research i have done shows that it is the on right under the oil fill tube ( F/L side of engine)

please tell me your kidding?? my cel flashes for like a millisecond at 6500 rpm under wot in 2nd,3rd, and 4th gear... you figure anything out?

iv been researching the p0340, people say its sometimes due to a timing belt so i changed mine with all new pulleys and waterpump/t-stat( all was due anyways) and still no progress. i have a cam sensor on order from Subaru and will see how it goes.

anyone else having this problem?

Exactly!! I do feel it stutter as well, or else it's my brain going haywire when I see my cel flash. I have another cam sensor laying around that I've been meaning to swap in. Glad I'm not the only one, we'll figure this out.

Ya. I checked the cam gears when I was doing the belt and they seemed fine. No chipped area, sensor also looked physically ok. Iv also read that putting a spacer on the sensor to move it out farther works also... Im going to try and talk to one of the techs at Subaru when I go get the part to see what they recommend for this fault code...

Good luck, I work for Subaru and most of the techs look at you like you have ten heads when you say, "EJ207?... JDM 2.0 STi?... it's a lot like the 2.0 WRX engine I suppose."

With that being said, I haven't put a lot of time into this yet, it's the end of the month lol

I work for bmw so i have a decent relationship with a few guys at the subaru dealer. and i was just going to ask them in general.. not about the ej207 just that fault code itself.. what they see and what ideas they have.

good news, I just swapped in another cam sensor I had laying around and it didn't do it once my last drive, did a couple solid pulls. Initial impression is that it's fixed.

Okay, so I ordered the part from Japanparts.

It ended up looking like the US gear that they sent me, and it's the part number 13322AA001. the gear that's currently on the motor is part 13223AA020. I emailed japanparts thinking they sent me the wrong part, and they said the same thing as IAP said, the 001 superceded the 020, and the 020 no longer is in production.

However, my tuner said that the us cam gears were different, and wouldn't fit. They're a REALLY reputable subi dojo out here in California, so if i'm going to go back to them and tell them that they're wrong and to throw this gear on anyway, I need to know WITHOUT A DOUBT that this part will fit. I'd feel so much more comfortable with an 020 camgear, but apparently it no longer exists

I just want this headache to end and my AVCS to work. the struggle...

Awesome. I'll be tuning my V9 engine with stock JDM catted downpipe and Prodrive oval axle back soon.

I ran an MBC on my USDM wrx engine (with professional tuning of course) but I'm considering doing a hybrid boost control setup for the EJ207.

Interestingly enough, the MBC allowed me to run the stock JDM rom with the Ej207 pretty safety without tuning because I had unplugged and removed all the EBC hardware. The JDM ECU was throwing a P0245 CEL for the missing EBC but I think it put the ECU in limp.

I ended up plugging the EBC in to clear the code but the car had been SUPER easy to drive without ever going over 7psi on 91 octane.

Engine is running great even on 91 with the factory JDM tune. Off boost torque is impressive. Can't wait to take it past 3k rpm haha.
