Aftermarket cooling parts weight

[alexevo]

I'm planning to upgrade Heat Exchanger and Auxiliary Radiators on my supra and looking for some light weight solutions, or at least not heavier then OEM. Please share weights on (AMS/Koyorad/Mishimoto/etc):
Heat Exchanger -?
Auxiliary Radiators -?
Transmission cooler -?

ps. Does anyone know the OEM weights ?
pss. on one of my cars I went with CSF radiators upgrade and it worked well but the weight was much higher then OEM parts.

None of the manufacturers share component weight, but all of them are heavier than OEM as the core sizes are minimum 1.6X larger.
