I would solve it with hose clamps. :naughty:



Actually, this is a little ghetto but if you buy a straight section of 1 1/8" coolant hose and chop it short, you can put it on the radiator and then slip the 1 1/4" hose over it.

Again, be generous with your hose clamps to prevent leaks. I'd use the screw type instead of the OEM squeezies. That way you can ensure it's nice n' tight.

BTW, that tiny little stock VX radiator may have some issues cooling the b18b if it's the same as my CX radiator was (which I think it is). Might want to upgrade to a beefier unit, even if it's just the OEM SI radiator or an Integra radiator.
