ok heres the deal.... i have a 1jz in my sc, the problem is that, it over heats everytime i put my car to the test.. i have a 16' and a 12' autozone fans on the car.... and same with both of my friends cars, both have JZs motor. so i asked my other friend with a JZX100 (chaser) he's running a stock clutch fan.. everytime we're at a event... his car never over heats... and we the electrical fans JZs always over heats.. heres my main question. what fan do yall think other then FAL will do the job that keeps me from over heating? what would yall prefer?

Similar prob, similar setup. I bought two electric fans (no name brand) to put into mine, but after some re-research I found out that only a small percentage of people who have say they actually work out as planned, I never installed mine and my 1JZ stays at around 210 degrees, not good. I just bought a fan shroud and there was no difference, so next is flushing the radiator fluid, then a CAI, then putting heat shielding around the exhaust manifold, then after that...i dunno.

Stock w/ shroud. Theres a reason Lexus/toyota didnt put electric fans on the radiator for these cars. And why your friends car doesnt over heat but yours does.

dude seriously if you check supraforums we all have gone through that problem. the solution is to install the stock fan and shroud.

I'm running stock fan, clutch and shroud. I flog my car at every stop light, even in 115 degree AZ heat, and have never even blipped the temp gauge. Go back to stock and your problems will be resolved.

^^ yep. I was riding in my friends 5m Mk2 supra with elec. fans yesterday and the temp was 90 degrees and he was like "wow, my cars overheating..".. yep, I was running 10psi in my mk3 and didnt over heat yesterday at all. Never even past normal

im running the stock sc300 fan on my 1j i had to cut the fan blades a little to clear radiator hose and pipe, and I have the stock mk4 turbo radiator runs fine no shroud.... also have new thermostat and pump dont know if that helps.

stock fan and shroud for the win. if you take a look at the japan drift/track soarers and supras, most of them have the stock fan and shroud. if the stock setup can cool enough for them, im sure it will be enough for us.

if this tread is still around in a few weeks, i can update will my personal experience once my car is tuned, as i have the stock supra fan and shroud.

Stay with stock fan/shroud. I never went above 180deg with my setup. A buddy switched to Electrical in his 97 TT MKIV and they malfunctioned on a highway pull and his #1 cylinder went bye bye.
