i've been told that the Y7 oil pumps are weak and i just happen to have one in my car. can anyone confirm this? if it's true, what are my options for upgrading the pump to keep up with hard driving?

sure you can... high flow pump

The y8 and y7 blocks are 99.5% alike. Only real design differences: the plug in the oil hole near the deck and the knock sensor. The pumps are known to not be adiquate for performance (lots of HP, or high rpm). Keeping your oil fresh is the best thing you can do. Swapping to a z6 or a6 block isn't a good idea, because most are beat to hell already, and the worn parts are just as prone to spinning a bearing as the new y8/y7.

anyone else agree with the sentence highlighted in bold? could that help decrease your chances of a spun rod bearing failure in a sohc motor, or perhaps any motor in general?

You can also shim down the washer on the spring loaded bolt in the oil pump to get more oil pressure to last bearing on the crank.
