I'll add this in detail fwiw.
Mine had Raceware rod bolts and nuts in it when I got it. They're reusable too so I did. They cost more than ARP rod bolts but I don't know if they're any better or different.
I took my 1987 911 turbo connecting rods to the best automotive machine shop in Lake Park, Florida to be resized and have the new Mahle small end bushings I bought here pressed in and honed to size.
Before doing that I called Raceware tech support and asked what torque the nuts should be tightened to. The guy said to 52 ft lbs in 3 steps: 20, 35, and then 52 ft lbs with 20w 50 non synthetic oil on the threads.
I told him i have some ARP fastener assembly lube. He saidnot to use it because it's too slippery and the torque value would be lower and he didn't say exactly what it would be... another words keep it simple and just use the motor oil.
The machine shop removed the bolts, machined a small amount off the mating surface of the rods and caps, reinstalled the bolts and torqued the nuts to 52 ft lbs with motor oil on the threads and then honed the big end hole so it would be round again.
Before they did that they measured the big ends to see if they needed resizing and they had become oval shaped by around .001" so they did need resizing.
When I installed them I did it like Raceware said to do.. with the 20w 50 non synthetic motor oil on the threads and in 3 steps: 20 ft lbs, then 35 ft lbs, and then 52 ft lbs. I used a 3/8 drive snap on click type torque wrench.
