GReddy FMIC coupler sizes? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I need the coupler size for my FMIC here. It's a GReddy FMIC, I just bought the car and am not in town (Iraq). I looked on a few sites and did a search for the silicone hose sizes, and got nada. I am sure it is a redcer coupler, but what size to what? It's the passanger's side lower coupler (The black rubber one in the pic. Previous owner home-depo'd it and toasted the t-25).
If anyone has or knows all the coupler sizes I need that would be even better, as I wouldn't mind replacing it all.

Thanks

If its a kit for a sr20det then its a 2 3/4 on both sides of the intercooler. And on the cold side there shouldnt be any reducers. On any blitz, greddy, hks kit, it is 2 3/4 piping all the way from the intercooler to the TB on the cold side.

And I am pretty sure most intercoolers reduce it on the piping and not the coupler on the hot side. So its either 2 3/4 or 2 3/4 to 2 1/2 reducer.

And its 2 1/4 at the turbo hotpipe.
