Nope, the only reason t2's need cool down time is becuase the oil in the turbo dries or something in it..... is all i know is you dont need cool down time.....

From my understanding the whole 'let the turbo car idle' was just that, so the turbo could have some coolant and oil running through it so it would cool down and not damage itself.
I've only let my GXL cool off at autocrosses.

I wouldnt bother letting it cool down unless the temp gauge was getting a little hot. Turbos need to idle afterwards because of the oil in the turbo. It gets very hot, just shutting the car off will stop oil flow. Leaving the oil to boil inside of the turbo, causing parts to warp and seals to crack. Having the car running makes the oil pump oil while it cools down.

Any engine (NA or turbo) should be left for a few minutes after really hard driving (track/autocross/drag) to let engine temps stabilise, but this isn't necessary after normal street driving.

i thougt that turbos failed more often when not given enough time to warm up AND cool down. as well as any engine you dont want to stomp on it before it warms up!! as far as cooling down...i dont think youshould give any engine high rvs and the n just shut it down.....i thought all engines should get a good time to warm up..like 10 minutes before you jump on them, especially rotories. and i would believe you should spend 10 minutes driving an na at regular speeds too!!

You should always let the rotary engine cool down for 30 to 60 seconds after you have driven it. Depending on how hard you have driven the car.
Do not drive your car over 3000 rpm until its is @ 100% normal operating temperature.

I'm also fond of letting the car cool down before I shut it off, even though it's N/A...it just seems proper. Same for warming the car up...never drive hard until the car is READY and WILLING to drive hard, it takes 2 to tango.
