Unless you are drag racing it constantly there Is no real need to go cement fill it. I am running a N1 block with custom 86mm CP Pistons to gain maximum bore thickness with stock girdle and the engine makes close to 900kw. It has had plenty thrashings still holding together quite nicely.

Cheers fellas! Good feedback! Seems like to the bottom of the welch plugs doesnt cause any problems so I will run with that.

XRATED - Ive already got a little 240v vibrating motor ready to bolt on my bench :)

NUR33 - I would have liked to put an N1 block in it but have already spent the money on the stock one so just chasing a little bit more strength / reliability.

Cheers Simon.

Great minds think alike... I'm 1/2 way though the install of my DC ally electric pump today.

I'm going to leave the mechanical pump in for a few reasons.....

1. I can't be assed pulling the whole face of the enginge off to rmove the water pump.

2. The mech pump will provide redundancey if the electric pump fails for any reason.

3. The underdriven N1 pump has a reduced parasitic draw on the engine, especially if it's not having to draw coolant.

4. I want to keep the stock fan hub and shroud arrangement, but will be gong to a gtek fan and adapter. I know I can press the impellor off the water pump, but see points 1-3.

5. The DC controller offers a fan out put that I'll be using to controll a thermo fan on one of my oil coolers.

Cheers

Justin

      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..

      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.
