Turbo outlet hose size st165

Tue Feb 26, 2013 8:28 am

I hate posting this, but I am having trouble finding the answer even through Google.
I am looking to replace the hose that comes from the turbo outlet to the Air-water on the st165, and therefore need to know the size to order it. I wont be able to see my car for a few days, and would like to order the hose when I order a new bypass valve tonight. I just need the internal diameter of the stock item. Thank you!!

Sorry if this is in the wrong place.

Found someone who did a FMIC and used 3" piping, also found a site that said a ct26 outlet is 2"~

It's 2 inches, I replaced mine recently. It's also 2 inches on the ct20b. For the record, the inlet that goes to the air filter is 2.75 inches.
Cheers

All right, that makes sense. I ended up going with a 2" t- hose. Thank you for the information.

For future refrence, and of course I found this afterwards: http://www.turbocelica.nl/howto-blowoffvalve.htm

Basically doing that, but with an upgraded bpv.
