RB25 Neo block water fitting front .

[discopotato03]

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 .

I tried Skyline Spares but they have no Neo Turbo blocks atm .

Cut it off, weld on a socket and use a brass 90 1/8 fitting of whatever size u need.
