Very nice. I love my Koyo. I used the stock fan, but I'm curious if there is any improvement with FAL fans.

Does the Koyo bolt right in or is there any modifications or fitment problems. I need a new radiator and thinking about getting the koyo. And the stock fan can still be used, correct? Thanks guys!

I'm not sure about The 1UZ but I know on alot other cars the factory clutch fan with fan shroud still in place will pull the same if not more air than electric fans. Electric fans are still good too though

here is my thread from when i switch to the koyo/e-fan setup 2 years ago... pics on page 2.
https://www.clublexus.com/forums/sho...=182996&page=2


The car runs at 165-180 even in traffic. Needle is at the line right below the halfway mark. Compared to my friends stock 5spd sc which runs at the line above the halfway mark.

You won't notice the power it will free up though. Either set-up is cool. My brother has the hydrofan on his 1JZ with a shroud and its legit

it's still reducing the parasitic loss on the engine, and that's never a bad thing.
