How to run 2g Aluminum/Stock radiator with a SOHC head
Review:
The difference between 7g and 2g radiators is the coolant filler neck (and minor size differences). The filler neck on 7g is part of the radiator while on 2g its part of the thermostat housing.

Making this work is very simple. You'll need 2g thermostat housing (just the upper part of it) and 2g radiator (aluminum or stock)
All you do is swap the upper part of the 7g thermostat housing with the 2g one. Its a bolt on, no modifications needed. Use some permatex (I have MItsubishi OEM grey kind) to seal the surfaces. Now its a good time to replace the old radiator hoses with brand new ones.
Here's the 7g thermostat assembly:

Make sure you grab the 2g cap, because its not compatible with the 7g radiator cap.
