Hi I couldn't find a thread with a clear answer with the torque setting for Arp head studs in a rb30, only info on the 25 or 26. Just wondering if the settings are the same, from what I can gather its 80nm if you use the molly lube and 100nm if you use engine oil. Is this correct?

more info if needed,

I have the 11mm studs. I got the engine dis assembled but it has been using the studs previously.

Any help appreciated, thank you.

My little instruction sheet says 87ft/lbs, tightened up a third of the torque at a time.

I'm not sure if they used lube or engine oil though.

They are coming out, as the head has the come off because the builders were dicks.

always better results using moly lube guys, here is the correct fastner torque setting list.

first column is ARP, second is ARP2000 and third is L-19

rod bolts are 45ft/lbs or 6thou stretch.

bolts must be cycled a few times before final torque for best results.

Thanks for the replies guys. The question I probably should of asked is will it matter if I get the torque setting wrong slightly. Every where I look has a different answer so I would be guessing not, as long as I was close. The std final stage tension is 88nm, now I know that is using engine oil and the average torque I found for arp with moly lube is 72 - 80. Id hate to get it wrong and have to pull the engine apart again or have it fail.

Check out the latest ARP catalog under the torque setting page and see what it is for an 11mm stud. Ive always done them to 71ft/lbs with moly lube. They could have changed it...

Just looked and it is 72ft/lbs now. Well there you go.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
