Guys, I need a hand....

I have got a 2.0 zetec turbo engine in my MK3 fez and it is running a standard MK1 FRS turbo and manifold.

I need a hose for the tubo intake/induction kit....

What internal diamater hose do I need from say SFS/Samco etc?

I would measure it but I don't have the car with me to do that and need the hose ordered pretty quick for Ford Fair!!

Thanks for your help in advance

Adam
