Where would i be able to source a boost restrictor hose?

My mechanic has removed my boost controller and boost is now low probably 0.5 he thinks its due to the fact that the boost regulator is now missing out of the hosing- makes sense... so need to source one quickly

If I go to a breakers is the part likely to have changed for each STI ? ie I have a V9 JDM STI is it likely to different to say an 05 STI?



Cheers

 

.Phone up Api or Powerstation

 

Does anyone sell the brass restrictors?

I'll just get an engineering firm to drill the hole for me (I've found .043" is the diameter on stock)- tell me if i'm wrong.

 

I would say those company i mentioned should be able to tell if the uk 05 sti restrictor is the same as 05 Jdm sti
