Hi all , need some info on the RB25DET Neo's front block water fitting .
Neo's have a rubber coolant hose that runs from the front air bleeder down to this block water fitting , this hose comes out from underneath the plastic engine cover next to the rubber fuel lines .
Thing I need to know is if the barb where the bottom end of this coolant hose connects is 10mm because it is at the top . R33s are 8mm at both ends .
The Neo's block water fitting is no longer available new and the part number is different to R33 .
Cheers A .
