Even if it is your time, your time is still valuble, so get OE parts and do it once, right, the first time.
It still amazes me how people want to cheap out (I can understand if they have no choice) when the OE parts were trouble free for 106,000 miles. Those parts work hard, and are key to the engines survival.
its possibel that 80.00 in savings can sot you a replacement engine.
Just go OE and have peace of mind (and dont forget to do the cam seals, main seal, waterpump and re-seal the oil pump).
If it was a matter of $80 or even $100 I'd be with you man; just get the OEM parts and be done with it. I've done that even recently with a radiator because those aftermarket ones are usually wrong size in/out pipes and copper so I got the right sized OEM aluminum one from the stealership.
However I just priced out everything for a full timing belt job and it's not a matter of $80; it's $379 dollars. I'll break it down...
$203.00 (including shipping)
$414.22 (including shipping)
Stealership (WITH A DISCOUNT ACCOUNT!)
Even the Subaru-Parts-Dealer parts, which are supposedly all OEM parts, is a difference of $211 dollars vs the Import Experts kit. Difference between discounted stealership prices vs Import Experts kit is $379. You could change the Import Expert parts twice as often than if you'd use OEM parts and still come out ahead $176.
I've got a non-interference engine with 199,000 miles on it... I'm betting these are the last timing belts I put on this engine =)
