Labubre Posted September 12, 2022 Report Share Posted September 12, 2022 Hi, Seems this part is hard to find right now... Would be keen to buy a set-up i would need to finalize the rebuild of my engine. Oversea shipment if possible but if too painful, i can get an adress within US. Thanks Seb Quote Link to comment

That happens with these old vehicles... I have ordered plenty of parts to just get an email saying it wasnt actually available.... Was that a stock bolt? I'd consider that a blessing it did it before you ran the motor.... Quote Link to comment

datzenmike Posted September 12, 2022 Report Share Posted September 12, 2022 '70 and into early '71 240z cars used the same 8mm L16 bolts, later changed to 9mm. You would have to buy 6 pair to get your 4. L16 .... 12109-21000.... 8mm L24.... 12109-21000.... 8mm https://arpstore.com/collections/nissan-datsun/products/hi-perf-8740-complete-rod-bolt-kit-for-nissan-datsun-l24-series-early-inline-6-m8 1 Quote Link to comment
datzenmike Posted September 12, 2022 Report Share Posted September 12, 2022 The bottom bolt threads are narrower!!!!! It's stretched!!!! from over torquing. I have 23-27 ft. lbs (3.2-3.8 Kg / m) tightening torque. Does that agree with your information? If yes have your torque wrench calibrated. If its over tightening, all the bolts will be stretched way past their yield point. Quote Link to comment
banzai510(hainz) Posted September 12, 2022 Report Share Posted September 12, 2022 (edited) Weird how there isnt that many avail. I had 2 spares but dont know whwere they are now. Matter of fact everybody should go to the ARP bolts. this is what this guy shows https://zcardepot.com/products/arp-rod-bolt-kit-l16-510# Edited September 12, 2022 by banzai510(hainz) Quote Link to comment
Stoffregen Motorsports Posted September 13, 2022 Report Share Posted September 13, 2022 I made a call to ARP a few weeks ago to check on the stock of another part (some super long 10mm studs for a custom project) and they said most things will be in stock by late September. Begs the question - why all at once? Quote Link to comment

Stoffregen Motorsports Posted September 16, 2022 Report Share Posted September 16, 2022 The higher 40 ft-lb torque is for the later, larger bolts. The early bolts need to be 27 lb-ft maximum. Quote Link to comment
datzenmike Posted September 16, 2022 Report Share Posted September 16, 2022 L20B and L18 rod bolts are 33-40. (per FSM) Correct and they are the 9mm size. Quote Link to comment
Labubre Posted October 1, 2022 Author Report Share Posted October 1, 2022 Finally ordered Through ARP. Found the Nissan part code since then 12109-N0100 Bolt Connecting Rod (TOKAI). Bolt Connector Rod. Part Number: 12109-N0100 Supersession(s): 11810-N0110; 11828-N0110; 12109-A3502; 12109-N0110; 12109N0100; 12112-N0100 Waiting... https://parts.royalmotornissan.com/p/Bolt-Connecting-Rod-TOKAI-Bolt-Connector-Rod/89402579/12109-N0100.html 1 Quote Link to comment
datzenmike Posted October 2, 2022 Report Share Posted October 2, 2022 I just assumed that the 9mm bolt would not fit the earlier rods that took the 8mm bolt. 12109-N0100 is for all L series engines including the L20B which were 9mm. If that's the case them L20B bolts would be a nice stronger upgrade for the early 8mm bolts. 396/427/454 BBC rod bolts will also work but I think the rod holes need to be enlarged.

Stoffregen Motorsports Posted October 2, 2022 Report Share Posted October 2, 2022 No, the larger bolts will not fit the smaller rods. Drilling rods and caps should be done by a machinist as they are aligned perfectly by the rod bolt and any slight misalignment will cause bearing wear. 2 Quote Link to comment

I think I had the rods resized also when I had this done to make certain of concentricity. Quote Link to comment
