Thanks for all the great replies. I've personally not seen Water temp issues anywhere near as bad as mine while driving other R34's and other GTR's on the track, so I was suspecting there was a more fundamental issue with my car, such as a head gasket leak. It sounds like a good idea to get the coolant checked to see if there's any combustion gases in it, so I'll enquire into getting that done. The big aftermarket IC was on the car when I got it, but I have the original one so can arrange to get it put back on. I'm definitely happy to install an Oil Cooler, I just wanted to make sure everything is working correctly.

The core problem is not only limited to the track - today I was driving (not hard) around in the ~30 degree heat and the Oil temp kept climbing up and hovered around the mid to high 90's. Water temp climbed up to low to mid 90's when moving, and when waiting in traffic went to high 90's. I then drove a little harder (not super hard) for around 3-5 minutes and Oil Temp went to 103 before I backed off. Water temp then started to rise and went to around 100. I've owned a GTR before and it didn't have these cooling issues, and I've also driven many other GTRs on the track and normally they cool reasonably well. So I suspect there's an issue with this car, so I would welcome any further suggestions on how to diagnose/fix it. Thanks.

Is there any way to test for these things to confirm if they are an issue or not?

Hi, I have a reasonably stock R43 GTR that is getting unusually hot on the race track. Other R34 GTR's I've driven on the track don't have the same issue, so I suspect there's something wrong with mine. The only modifications are Pod Air Filters, Cat Back Exhaust, FMIC. And it now reports ~1.0 bar boost, spiking at around 1.1 bar. After 2-3 hot laps (or less) the Oil temp starts to climb over 100 degrees. Then the Water temp quickly climbs to over 100 degrees. Oil and Water temp both keep climbing rapidly until I back off (I've seen Oil go to 115 and Water about the same). Temps will slowly reduce when I do slow laps. Temps on the street are OK, but sometimes get a little high on hot days (Water temps close to 100 degrees). I don't drive hard enough on the street to get the really high temps. I've had the following done, but the problem still persists (though temps have improved slightly). - Koyo 50mm Radiator (fitted new) - Nismo Thermostat (fitted new) - Coolant changed - Royal Purple ICE added to coolant I expect I could fit an Oil Cooler to reduce the Oil temps, however I don't want to mask another issue. Any suggestions on what I should check or change next? Thanks for your input. Geoff.

Thanks. Yes, they're Sparco rims. They are specific for a GTR, but I've only ever seen them on one before - maybe yours.

Hi, do you still have this available for sale? I 've just bought an R32 GTR and need to replace the Microtech in it. Thanks.
