Message	Replaced these after 40k miles. The setup was producing 426whp and 420wtq at 17psi pump gas. Always ran Mobil 1 10w30. Daily driven all season in Georgia. Summers are as hot as 95 and winters sometimes as cold as 25. To think I drove that car without AC for 2 years! Ha! I will definitely be overhauling the AC system this time around. Here are the rod bearings [[[ http://i892.photobucket.com/albums/ac122/Zlicktop/IMG_1505.jpg ]]] Looks like some trash went through #3 The main bearings were in excellent condition Are you going to try the thicker oil? Although your wear was consistent and mild both builds, 15k miles isn't much compared to the distances an originally built Nissan motor goes. Of course it is a 600hp beast so of course bearings will wear quicker. Is there no other remedy? You said you used Nissan bearings, are there other bearings that are made to support higher power and last longer?
