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!

      yeah I have brown peeking out from in between some metal sheets close to the hood hinges. Strut towers look fine, even around the edges. some images https://imgur.com/a/brGt3Tu the one that looks the worst is the panel(s) going away right near the firewall on the passenger side, from underneath. Driver side does not look that bad.

      I presume you are talking about a C34? Have you seen the buyers guide? https://www.sau.com.au/forums/topic/92065-buyers-guide-the-nissan-c34-stagea/ It's what got me to sign up to the forums when I bought mine. What kind of insight are you after? Up front I'd probably suggest to not get tempted by the poverty-spec models. I can't imagine a RB20DE to be engaging to drive in a 1600kg car.

      yeah I try to be positive. Time will tell what becomes of it. Realistically my only other choice than to just deal with all the issues is to walk away and just sell it agai, at a loss.     I know a fair bit about these cars and knew before buying. I will try to deal with the rusty spots without tearing apart the metalwork for now. Sooner or later I probably will have to bite the bullet and do (or ge done) the arguably worst job an a 33/34 Skyline.

      I'm aware that you can sink endless amounts of money into an engine. I don't want that kind of engie though. My power goal is 500, maybe 600hp at the max. I can get by with the nearly stock engine that I have now for that purpose and if it does need a rebuild at some point I would choose longer lasting components instead of the most ridiculously hp-rated ones. And do all the essentials of course.
