#188706 i was just wondering if radiators for b series are interchangeable. meaning will a LS radiator and hoses connect to a gsr and vis versa? thanks.

#188715 all the integra radiators are the same, and all civic radiators are the same,

but if you have a b16 in a civic you need the integra lower hose (there all the same) and the delsol vtec upper hose

if you have a gsr in a civic, agin you need the integra lower hose and the gsr upper hose

if you have a LS/B2O in a civic you need the intera lower hose and LS/B20 upper hose


the only differences in the hose's you use for a b swap depends on what head you use as i stated above, personally i bought the delsol vtec upper hose but got it in the univeral flex style hose so i can use wich ever engine i like...

but to answer your queation, if you put a ls into a gsr integra or vis versa you would prob need the gsr upper hose, but the water neck outlets are close to the same place so it very well could work... hope this helps... :thumb:
