ray007 Posted November 2, 2009 Share Posted November 2, 2009 I have a 1st & 2nd decat for my j-spec TT which im about to install but i cant find the Restrictor ring. I have a Blitz boost controler (DSBC) - IIRC the UK specs dont need a RR but need a boost controller, could i do the same with the j-spec??

bradleyh_15 Posted November 2, 2009 Share Posted November 2, 2009 you will suffer over boost without the restrictor ring! Not safe! check whifbitz and possibly the for sale section on hear for one! Quote Link to comment Share on other sites More sharing options...

heckler Posted November 2, 2009 Share Posted November 2, 2009 Boost controllers only raise the boost. They cannot lower the boost. So, you need a restrictor ring to bring the boost to a safe level, then use the BC to raise it. Reason why the UK's don't need a ring is because they have larger wastegate Quote Link to comment Share on other sites More sharing options...
