Guys got an issue with the boost pill. Mine was missing when I bought my bug sti so I replaced it with a 1.00 mm welding tip and worked fine boosting at 1 bar. I seen a poost pipe for sale on the bay from america with what they said was the correct size pill 0.8 mm so I bought and fitted it but after a short drive water temp rocketed up and hose to turbo from header tank was roasting! Im taking it off again and putting the welding tip back for the moment but just wondered what the heck is going on to make it run so hot? It was boosting way too high as well .

 

You can buy the correct size pill at a Subaru dealer. I bought one for my rb5.
