2JZ cooling issues, is it my electric fans set up?

[leecheater]

Hello All,
I have a 2jz in my MKIII. Last summer I had some issues with cooling. Not huge problems, she didn't over heat but got warm on several occasions. I have a new Moshimoto radiator, the engine was cleaned well when we had her apart, my thermostat is new Toyota. I also have the Adrenaline electric fan set up with custom shroud, and a Turbo A duct. Fans are set to run all the time.
I am shooting for pretty big power #s this summer and don't want cooling issues. Has anyone made a custom shroud to fit the 2jz/MKIII combination? If so I would love to see it. I know the 2jz has pretty good cooling, we didn't like the Aristo set up and took it out. Going to the USDM fan setup is an idea. Any thoughts or ideas appreciated. She will be pushing 800rwhp once my new turbo and tune is complete. Would love to arrest this problem before I jump up 200 h/p.
I would love a few photos if you have them.
Has anyone added a 3rd electric fan? Photos of my set up below

I had the FAL 220 fans on my old 2jz swapped car with stock twins. It cooled fine with the stock radiator. When I had the a/c on full blast in 95+ heat and on the highway it would run warm (215-220 via aem).

I would say its your fan shroud design, it looks like there is no shroud really just a metal plate over the radiator, which would cause the air from the fans just to be coming from the 2 spots the fans are vs the whole radiator.

Thanks guys, I am planning on removing the shroud and opening it up. I may make a custom one. It all else fails, I will put the mechanical fan in. Anyone running the 2jz OEM fan with a custom shroud??

Why dont you get a hydropump setup from a 1J? I think that is the best cooling solution available for your setup. I have one with a 2J setup and a KOYO radiator.

csnow, It is an option. I think we have the old hydro pump from the Aristo in my parts pile. Easiet solution is going to be opening up the shroud, if it fails then perhaps you are correct.
