Re: How about a REAL discussion about LS rod bolts?
Thanks guys for all the great info so far! It's exactly the kind of discussion I was looking for.
HiProfile, when you say the motor threw a rod, would that be a result of anything with the rod bolts? Thanks for you personal experience.
B20Pete, your experience is quite helpful.

Re: How about a REAL discussion about LS rod bolts?
I look at it more as peace of mind, to reiterate on what Chris said. These motors are getting old. You wouldn't got out and spend the money for a factory turbo'd porsche and then run regular in the tank, kind of the same deal here.

Re: How about a REAL discussion about LS rod bolts?
I agree, slo, it isn't like ARP is expensive either. My stance on the subject is that bad tech like this is the product of illogical thought processes and bandwagoning. Both are counter productive; while these engines are getting old and any serious (even budget) build will use ARP or better yet TT rods, if your mind is trained to follow other people's illogical thought processes instead of thinking for yourself then your build will be flawed. Unless you follow HT doctrine of "replace everything at top dollar prices because I'm too stupid to think," of course.

But I'm entirely sold on the idea that most broken engines are from user error durring assembly.
BTW JD, I'm curious about your 'big end' statement. All d16/b16/b18's have the same rod journal size of 48mm. Its the width that is different - B18a/b,B20,B16 are widest, then d16's, then b18cX's. At least says my info sheet. I can't see it being wrong in many spots though, everything I've been able to check is correct.

itr pistons in a b20 huh. 3mm difference in piston to bore there seems like it might be an issue

well while were at it b20's especially b20b's are basically being handed out at importers these days low mileage much less than your typical ls block but then you have issues with the sleeves.

Other than that, his IIRC could only be good if he was using muffler spacers around the piston so he wouldn't get blow by. You can get those @ most Import Shops nowadays & they sell them in sets of 4.

ITR spec pistons have been made in a number of sizes for years now.
Still, I don't think that's what he was referring too.
