Size of SR T25 banjo fittings? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have no water lines for my turbo (SR T25)/engine (CA18DET) so I need to make some. Thing is, I don't know the fitting size on the turbo itself. I see that I can get some Earls banjo fittings, but I just don't know what size to order. Either that or I can make some nice push-loc fittings. Either way, I still need to find out the size! Anyone?

For all SR:

* Water inlet on engine - 14mm x 1.5
* Water inlet on turbo - 14mm x 1.5
* Water outlet on turbo - 14mm x 1.5

For S13 SR:

* Water outlet on engine - 3/8" clamp on

For S14/S15 SR:

* Water outlet on upper radiator hose water outlet - 14mm x 1.5

If you have an S13 SR, you can get the S14/S15 water outlet and return water there. Then you can plug the return line near the firewall.
