I agree. The new engine definitely has some big shoes to fill. Like I stated in a previous post, I can push the Mazdas beyond 30K hours. They get a bit drippy and burn some oil, but the darn things will run. Very rarely have had an issue with the long block other than rear main seals going out... usually around 20K hrs. Replace that and the converter seal at the same time, and then keep on trucking for another 5K-10K.

From what I can tell, the water pump on the PSI is driven off a separate accessory belt, so there is one less thing to cause a timing belt failure. Also (in theory anyway) should make the scheduled service procedure less complicated.
