Hi I have been generously donated a standard recirc dump valve from a SN member but am unsure if it’s the right one for my car.
My car is a MY97 STI and it had a VTA valve on it when I got it
The STD valve I have here has a much smaller diameter inlet/exit than the connector on the inter cooler and return pipe.
Does anybody know if this is from an earlier car or am I missing the reducing pipe work

Appreciate your help I want to get rid of the VTA

 

Anyone?

 

Hi
I stand to be corrected, But I think you have been given a series 1/2 std dv and Im sure the series3/4 std dv is different , ie bigger bore .
Regards Matt

 

Hi thanks for that.
So does anybody have a spare one??
Or can somebody please tell me the part number of a V3 Std valve??
