Rb25Det Bypass Valve Hose Size And Intake Hose Size?

[Touge Kyousou]

Does anyone know on an r33 rb25det what size hosing i need to buy for the oem bypass valve to the return piping?

Also would like to know the size of silicone coupler i'll need for connecting the factory inlet manifold to the factory J pipe on the same motor.

Would save me pulling mine off, re-installing, buy, then pull off and install new ones.

Thanks all.

For anyone searching etc.

I bought a 3" coupler and that fitted.

The recirc valve I managed to use 1.25" hosing. Was actually a few mm too big but the steel clamps/ties still seal.
