AndrewOW Posted June 9, 2006 Share Posted June 9, 2006 Hi everyone/anyone! I have a J-spec 1993 Supra GZ TT, which is virtually all standard at the moment. I'm really new to all this! Searching thru the forums, although entertaining and educational, are daunting too! I would like to upgrade my stock exhaust to a Blitz Nur Spec R, and as the car has previously been fully decatted, I really would like to know if I only need to buy a restrictor ring to control the boost. Mark at Phoenix (where it was previously serviced) recommends I buy the two sizes, 45mm/55mm, just to make sure I get the correct air flow. As they are @£25 each, I would prefer to make sure I only get the correct one if possible. I would also like to know what problems I could expect from doing all this to the overall set up. The rest of the car is totally stock, except for the Walbro fuel pump. Any help would be really appreciated. Cheers Andrew Quote Link to comment Share on other sites More sharing options...
