What you're asking is rather moot, as 99.9% of the people only use the rod bolts when either upgrading to MUCH higher power (over 300whp) or they are building NA. You'll grenade a stock engine before you ever reach the maximum capacity of the bolts.

Re: questin about power potential (turbo-crx)
Rod bolts are primarily for high-RPM, or rather high-rpm will stress the bolts the most. Usually too much power will bend the rod in half in the middle - the bolts will be fine. High-rpm will pull the piston from the crank at certain points, ovaling that big end opening, forcing the brearing into the crank on the sides (among other things). Rod bolts help this a bit if they are resistant to stretching.
Long story short, 350whp maxed for LS rods IMO, based on safety concerns. People have gone with more, others have destroyed their motors with far less. It depends on so many factors that we say 250whp max SAFELY/daily (this assumes 20k worth of life). Even with ARP rod bolts. If you port the head, get a vtec head, or get cams before upgrading the rods meaning you can now rev past 7.5k), you're more a fool than anything. You're playing the reverse lottery - saving $300 but stand to lose $1500 or more.

ok heres the deal im building a motor but times are hard so it's slow going. ive got a stock b1 with170k on the clock in her right now making 274 to the ground @10lbs, and i figure if i can get away with 35$ in rod bolts and 9$in an oil pan gasket and make 350 (not too worried about the motor here) it should be fun for while till i an get the odds and ends the fun motor needs
plus i paid 150 for the long block borrowed the intake mani and bought a intake gasket for 12 bucks 2 years ago, so if it goes im not out much
