As per topic, just inquring on the normal operating temperature for an R33. I have owned the car for about 3 months so not sure what is normal. It has a Blitz water gauge that reads in the mid to high 80's from driving normally.

Does this sound correct? At what temp would I need to be concerned. BTW it has a larger radiator.

Cheers,

I also wanted to query this...

I have an aftermarket temp sensor in the top hose (which is i gather just after where the OEM sensor sits?- in the housing just before the top hose)

anyway, this thing reads 86 degrees stable as the point where the thermostat has opened and obviosuly circulating coolant- i.e. it is the lowest operating temp indicated with the motor at operating temp.

But if i plug into the ecu it is displaying 72 degrees.

any body know what the gig is here?

Your coolant temp sensor could be slightly out. New ones are about $30 from Repco but you need to match up the part by picture or go to tridon's website and find it there. I forget the number now

are you referring to a replacement for the aftermarket one i have or the OEM one?

OEM

My gauge shows 10 degrees above what the laptop says, so Dan a new sensor will fix it? Or could the gauge be out?

Well, the gauge could be out but your CTS is 15-20 years old if it hasn't been replaced. 10 deg isn't much. Noel's black 33 had a similar issue where he thought it was getting super hot but I replaced the CTS and it all came back to normal readings

mine ran over 85 a while back and i could hear it pinging so i dont think over 85 is too good

If thats the case i dont think the temperature is your problem.

The stock thermostat isnt fully open till 85 odd degrees anyway.

Mine sits around 85-88.

Even into the 90's isnt a problem.

the pinging was related to putting on a quiet restrictive muffler, and that seemed to increase the coolant temp's as high as 89deg,

these days it wont go higher than low 80's.

have you noticed the car loosing any performance when its running at 90deg?

So then id say that the restrictive muffler had everything to do with the pinging if your car was tuned to a more free flowing item possibly. Not coolant temps?

No performance loss whatsoever running into the 90's. I only had my tune dialled back when it went over 99 degrees. Boost limited to 1bar. I pushed it up to a peak of 107. heh. Was getting frustrated with only getting in 2 hot laps before it was cutting. Then found out that i only had a single core non turbo radiator dealing with 290rwkw :) Cant say i looked at it that closely till then lol!

      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.
