Description
This is a Koyo dual pass JZX100 aluminum radiator with an aluminum fan shroud kit.
Benefit of running a JZX100 radiator in a JZX90 is that it is larger then the 90 radiator.
Shroud kit will come with dual SPAL Medium profile 12" fans with curved blades. Each fan pulling up to 1328CFM.
This will drop in to a JZX100, however for the JZX90 it will require some additional modifications.
For the JZX90 fitment, it will requires JZX100 radiator hoses, Supra 2JZ water pump, and upper radiator brackets from a 100 or is300.
We also recommend using the DriftMotion 1JZ/2JZ Non-VVTi water pump pulley.

This is the cooling mod to get!
Changed out my jzx90 hydrofan for this jzx100 radiator and shroud setup (+ other supporting components). The spal fans were hooked into my LINK ecu and I couldn't be happier. When they turn on, I see coolant temps dropping nearly instantly. The shroud is really tight fitting and speed flaps are a bonus! TFworks is always high quality in their parts and support!
