    I noticed there was a spot for an allen wrench on the exhaust camshaft. Unfortunately, I did not have the required size. A cheaper solution than the special tool no doubt.
    I figure I saved 450$ in labor by doing the job myself even with buying 80$ special tool.

    Yeah, the more I think about it, I'll probably just pay to have it done. I'm sure I COULD do it myself, but I'm just not sure if I really WANT to do it myself. I've done everything else on the car myself, but none of that would ruin the car if I messed it up. I'm just not too keen on having the heads rebuilt if/when I bend a couple of valves.
    Has anyone gotten an estimate on changing the belt along with the idler pulley, tensioner, and water pump? Also, is there any advantage to getting the STI belt as opposed to the standard WRX belt?

    Did mine with the help of a friend, wasn't too bad. Took us about 2 hours with the obligitory celebration cigarettes after each major accomplishment and the 5 minutes to compress the pin on the tensioner

    I got a labor estimate of $560 from the dealer not including parts. I paid 250 for the upgraded STI belt, 125 for a new tensioner, and 130 for the waterpump.
    The only way you will bend a valve is if you turn the intake/exhaust sprockets the wrong way. When you order the upgraded "pink" timing belt it comes with an installation guide inc. a diagram on which way to turn the sprockets. The major problem I ran into was all in my head. I had to fight the valve spring pressure thinking I might be bending a valve. If there had been someone with enough experience to tell me what the deal was and not to worry, it would have saved me some valuable time. As far as the standard wrx belt vs the STI belt, I would imagine the STI belt is more rigid. I have not experienced ANY belt noise with the upgraded belt.

    I'm sorry to add to your post but i have a question. While you are replacing the timing belt did you bother changing the cam gears to a bigger size or increased tension? I'm about to change my timing belt as well and i was curious if it was worth the money to replace the cam gears while I am in the engine area

    u dont need to change the cam gears just make sure u check the tensioner for oil on the top bc if it dose have a little pool of oil ontop repace it $270 from subaru but its better than it going out and dropping a valve or bending one. and there is no need for more tension then tensioner on the subaru is a oil hydrolic tensioner desigend and ment to keep a constant tension on the belt whether idleing or at high rev.

    as for 03crazytaxi next time use a bench clamp u can do it in 5 sec.

    for psycobooe yes the Sti belt is a little stronger.
    (granted the Sti has more HP)

    12,14mm socket (timing belt pullies)

    If I were you, I would also order the Camshaft sprocket holder from skyway(SIR tool SU030) I did not have this tool and now my hands are cut up. You can do without but even with a second set of hands it makes life hard.

    I replaced the tensioner and water pump as well.

    BTW, I have an STI, you may need a different crankshaft sprocket holder if you are doing the belt on a standard WRX.
    Does Subaru make the camshaft sprocket holders? Does anyone know the part numbers for them if they do? Thanks!

    More than meets the eye.

    I tried to order the specialty tools from my local subie dealer and I had no luck. The answer I kept getting was "we get all our tools from the Snap On truck." A load of BS if you ask me.
    Call Skyway Tools, they make cam sprocket holders as well as a crankshaft pully holder. You can do it without the cam sprocket holder but I dont reccomend it (can be quite a pain in the ass if you are doing it by yourself). I held those suckers in place and it tore my hands up good.
