Default Questions and recommendations regarding JDM STi radiator and hoses

Hey guys,
I'm looking to upgrade my radiator and hoses on my 2006 JDM Hawkeye STi (EJ207).
I wanted to go for the mishimoto radiator (https://www.mishimoto.eu/fits/subaru...diator-01.html) + fan assembly but the description does not list the EJ207 as compatible.

I was also wondering if the radiator hoses from mishimoto (especially the ancillary hoses) will also fit the JDM model? I'm guessing not except for the top / bottom radiator hoses.
I found Fuji Racing top / bottom and heater matrix hose kit for JDM STis but sadly its not a complete kit.

Does anyone have experience with the JDM model fitment and radiator and complete hose kit recommendations?
Thanks!

MushyMoto isn't any form of upgrade in our experience and in general they appear to be far eastern / chinesium products with a fancy sales program / promotion............

std rads perform very well and if you do indeed need some form of upgrade then personally a KOYO rad is the only one I would spend my money on

good to know, thanks.

I will probably go with just a new fan tray + radiator hoses then as the current one is broken anyway and the 20 y/o hoses are leaky :/
