Well im the same, i dont really want to build it unless it goes bang. And if i did build one, id probably do a 3L. I have heard similar things, that RB25 rods aren't that bad. They aren't as good as GTR rods, but aren't usually the main cause to engine failure unless revved hard. I also heard that replacing the stock rod bolts with ARP items helps keep them together and this was a discussion that came up regarding whether you could do it by taking the sump off as it would be a relitively cheap upgrade to aid in keeping it all together. But yeah, i didn't think it could be done. However at the time i forgot about the ringland issues with RB's and if something was going to fail that would probably be it.
How long has your stock bottom end being pushing that power for?
