David i have the dump valve from my sti3 with all the pipework, you can have it for 25 quid

Isn't the STi 3 setup different mate? My car has the dump valve coming off the front of the IC, as with the later models. I thought the v3 had the dump valve sited near the turbo.
The sti v3 and v4 have exactly the same setup, you are referring to pre 97 setup with the 90 degree inlet. the post 97 like ours has the straight entry and dump valve coming off the intercooler.
