Can anyone tell me if a HKS SSQ dump valve off a 95/96 jap import impreza turbo will fit a 96/97 uk spec turbo.....any help would be great.

 

Is the same dump valve, but may need a different fitting kit. Not too clued up bout imports.

 

I have got a HKS SSQV that came off a STI4....I'm sure its not working properly it only seems to make a chatter on lift off that comes from the induction kit....I don't think the main valve is opening enough....Did they make different ones with tighter springs for higher boosting cars etc....I have a my97 UK
