First, I would like to confirm with a GTM 70mm radiator properly installed, along with using Uprev to reprogram so that the fan turns on sooner ( Maybe at 190F ) with a little more fan duty cycles, along with just a 25 row Setrab oil cooler properly installed, there is NO WAY you will ever get the oil temperature to even close to a limp mode. I have proven it already many times:

Driven at 125F constantly at medium to occasional high rpm for about 6 hours across the San Bernardino county to Vegas , oil temp never exceeded 210F, whereas without the radiator mod , it did get up to 250F ( Even with the oil cooler installed)

Now, if turbocharging the vehicle at 11 psi, it is IMPERATIVE that you must have the cooling system property modified like I did, or else there is a big chance that the Z factory radiator will be insufficient to cool down the additional tremendous heat even with the fan running at all time.... since the darn thing is so crappy cheap with a narrow single row. The alternative for a cheaper cost is to use the CFS radiator, which is a direct fit. While the CFS radiator cooling capacity is not nearly as good as the GTM 70mm radiator, it is still quite a bit better than the factory unit.

These are the links to my GTM radiator installation:

WARNING : If you blow the engine in anyway, especially the head gaskets, you will severely overheat the engine does not matter what radiator you have. Just a reminder and I am sure everyone knows this.
