I'm not sure how to ask this question. Concerning the RB26 bottom end rebuild..

Do you guys see any problem with having a machine shop do the majority of work, but NOT sizing bearings (I'd like to do this myself) ??

I am weary of having someone in the US completely rebuilding my bottom end. I'd rather send the block out for machining and pistons/rings/rods fit, same with the crank (check/microfinish/ballance).. and double check their work then size bearings and reassemble.

What do you guys think of this? Bright idea to minimize someone elses possible error dealing with a rebuild on a motor they probably have not seen before, or should I be trustworthy and have a shop do an entire bottom rebuild for me? If they do, I will have to source bearings for them depending on their abilities (hassle hassle).

What'cha guys think? :)

If you know how to do it, you have the tools, the time and a nice clean area to do it in then I'd say go for it.  Why wouldn't you?  Even if you were over here and you had all of the above I'de say go for it.

I have only rebuilt stock motors.. I've never used aftermarket parts to strengthen a motor above it's stock potential.

For some people, I know there are certain steps to be taken building a high hp engine vs. stock rebuild. If I can have a shop do all of the heavy work while I size bearings... is that going to be ok? Looking for answers from experienced people (not that you aren't.. I dunno). :P I don't want to overlook something.

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      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..
