I'm just about to order a second hand forge dump valve from eBay just to see if my car actually likes it or not because I believe that I can make them run like crap!!!!!
Anyway, I don't think it comes with the blanking bung thingy so I'll need order that too, any ideas on what size is need? Its going on my99 UK turbo.

Thanks

 

on my blob eye i made my own and im quite sure its 1 and half inch o/d (38mm )

 

Mine was 32mm but have since removed it as it did my head in!

 

Was that on a classic? I've had a look around and it seems that people are saying different things! Very confusing :s

 

Oh **** sorry just seen its for a classic. Mine is a new age. Apologies!

 

No worries mate, I'll get the answer in the end
