Co0ke Posted February 23, 2013 Share Posted February 23, 2013 I'm sure it's been discussed but I can't seem to find the info I'm looking for. I'm doing a turbo build and need to buy new connecting rod bolts, it's my understanding that they are torque to yield and can't be reused. Correct me if I'm wrong. I'm trying to decide on a few options Buy con rod bolts from motorsportauto...3.02 a piece. Pretty cheap not sure if I need to get new nuts as well? Buy ARP con rod bolts off eBay looking at 70-80 buck for bolts and nuts. Guessing these aren't torque to yield and can be reused? First time engine builder just want to be educated. My hp goals for this engine are around 250rwhp. I ordered clevette perfect circle bearings for the crank and rods. Got the standard size. I read somewhere that as long as there was no machine work done on the crank to go with standard size. Makes sense in theory....correct me if I'm wrong here as well.

BluDestiny Posted February 23, 2013 Share Posted February 23, 2013 I"m guessing your plan is to turbo? I'd go with ARP bolts just to leave room to expand your hp. As for the bearings, did you measure the crank? You never know if there has been machine work before. Or maybe you do. Quote Link to comment Share on other sites More sharing options...
Xnke Posted February 23, 2013 Share Posted February 23, 2013 The OEM bolts are not one-time-use, but they are the weak link in the stock bottom end. Go with ARP and don't look back. Quote Link to comment Share on other sites More sharing options...
Co0ke Posted February 23, 2013 Author Share Posted February 23, 2013 Went ahead and measured the crank pins 1.9675in within spec:). cant measure the journals yet. I'll order the ARP bolts. Thanks for the advice Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted February 23, 2013 Share Posted February 23, 2013 I'm using ARP rod bolts also, they're great. Quote Link to comment Share on other sites More sharing options...
Sam280Z Posted February 23, 2013 Share Posted February 23, 2013 Before you install, mic each bolt and record it's length. Keep track of which bolt goes with which cylinder and side. If you ever have to disassemble, you can remeasure the bolts to see if they have yielded or if they can be reused.
