You can choose to do what you want, it seems there a lot of good advice. Honestly, go with the parts DieHonda supplied. I got the timing kit from protege garage (idler, tensioner, tensioner spring, belt) for $129.99 with free shipping. Goodyear Gaterbelts from AutoZone and the water pump from advanceautoparts: ASC with limited lifetime warranty-$78.48
Though in general, just make sure it seals before putting the engine back together. Honestly I could have done without the paper gasket, but simply used it to guide the screws since the blue RTV was still not solid yet. Honestly, I will probably not replace this pump till I hit 202,000 miles. I will honestly worry about it being a pain then. Though honestly I do not see the big deal as to why you should not use the gasket.
By the way, maybe it's my imagination, but why are a few being negative about how long I took and way I do things? (uhm) I am simply trying to help out others so they understand what I experienced. Yeah if you got more experience or a mechanic it might take you less time. This is my daliy driver and I took off time to do this right and not rush. Honestly, Mazda made it pretty easy with the markings on the cam gears and crank gear.(2thumbs) The more I work on this car, the more I come to love my mazda.
