Advice concerning cooling with FI
Here it goes... a friend of mine is thinking of installing either an S/C or a TT in his Z. But the issue over here (Qatar) is high temperature (up to 55* Celsius) with extreme humidity. What system do you recommend? and what is the ultimate cooling system which should be followed for either option.
I personally advised him to go with the TT. But what is the "already ready" cooling system that should be bought in this context... if existing!
Thanks in advance

For cooling,
koyo radiator
nismo thermostat
oil cooler
samco hoses
with all of the above my car still overheats nowadays when i drive it hard no matter what. I never drive my car during day light. humidity here sucks big time. i think a supercharger would be ideal for our countries since it wont generate the stress and heat a turbo'ed car would make.

I can feel you, the same here in UAE one of my friends have the Jim Wolf Kit added a 3 row koyo radiator + 2 Fans between the rad and the engine, the temperature is absolutely normal even cruising at highways at 200 KMH or driving in city at noon when its C, we chose Jim wolf because there turbos are water cooled APS is water cooled but we wanted something different, water cooled turbos proved there durability on our land cruisers and Nissan patrols in our region,,,

how much boost is your friend making and is he facing any overheat when he's racing or driving it hard?
I assume the 2 fans are custom made. mind telling where he did them?

I have the thin 36mm koyo. I'll switch to the 53mm and see if there is any difference.
anyone know if the thick koyo rad will fit with APS TT?

that explains it, JWT's stock boost is ~6 psi. try to up it to 10-11 psi and see if there is any difference in coolant temp.

IMO its how fast + the volume of the coolant you cool down.
larger radiator helps cooling more volume of coolant but with the same area or lets say with same amount of air that goes through the radiator it will take more time without the aid of fans,,
Fans will pass more air through the radiator which will cool down the coolant more significantly specially if you have a small radiator and if you usually race at lower gears being at high rpms most of the time, your koyo i think will be fine,
try fans first and see what happens,,,

keep your stock undertray on.
get a vented hood that has holes near the front of the hood to vent out radiator heat.
ARC radiator (or Power Enterprise), super efficient dual row radiator.
large oil cooler
remove all the plastic shroud that is next to wiper blades, i noticed a 5-7*C drop in water temps when i did that on the freeway.

I have the AMS radiator, jwt tt running boost at 11 psi. I have no over temp issues at all, today the 85mph 70 mile drive home was around 90F to 105F as it has been the last month, my thermostat sits were it always does, not a hint of problems at all.

At idle and when cruising the temp is normal. it only overheats when I push it hard for quite sometime, it doesnt reach a dangerous level but still overheats, then it goes back to normal temp when I let of the gas. this been happening to me for over 9 months now. I dont believe its a headlift, no air in the cooling system and i did a compression test, all good. guess I'm gonna try those huge fans kits and see if it makes any difference.
