Default Fans and pulleys

I have been looking and was wondering if I would benefit at all from upgrading my pulleys and fans on my supra. I tried researching the pulleys and fans but all I can find is hit and miss stuff like you should switch out fans when upgrading to a single and it will cool the engine more. With the pulleys I have read that they reduce the rotating mass which will mean around ~10whp.
Any insight into this?

Unorthodox pulleys or greddy

Aftermarket pullies could provide a small hp gain (eg. 5hp - 10hp). This is most critical on engines that can't produce a lot of power to begin with (eg. Honda ), or if you're going for a particular configuration (eg. BPU+++++ - trying to max output of the oem twins).

Then AAP fans look great and give you more space in the engine bay. They also allow you to see the expensive, shiny aftermarket pullies you put in. However, they do not outperform the oem clutch fan - especially when roadracing in hot weather.

No. The belt-driven oem clutch fan is equivalent or superior to all electric fans.

The best ones I've heard of is a kit sold by ARD (formerly AAP):
