Irvy Posted September 14, 2004 Share Posted September 14, 2004 hi to all newbie to the upgrading on here...but followed some advice from the forum and had envy fit an FDC and remove the first cat. i then installed a blitz sus and had a nur spec r fitted....sounds good with the muffler in the nur-spec. taking the muffler out i do seem to get a bit of a misfire sound. Should i be looking at gauges to limit boost...or should i just look at restrictor rings mentioned on here...any advice greatly received Irvine Quote Link to comment Share on other sites More sharing options...
terribleturner Posted September 14, 2004 Share Posted September 14, 2004 This is the area im about to enter. Have yo changed your spark plugs yet?? May be this. Do a search, sure there was a thread like this today or yesterday. Quote Link to comment Share on other sites More sharing options...
merckx Posted September 14, 2004 Share Posted September 14, 2004 Yep I mentioned the plugs a few days ago Plugs A Boost gauge will only show the boost level, it cannot be used to alter it. Best to fit a boost gauge anyhow so you can monitor the boost to make sure it doesn't go too high and damage the turbo's. The consensus is that taking them upto a max of 1.2bar is okay. Fitting a restrictor ring can be used to reduce boost but if you still have one cat still in place this will be probably enough. Quote Link to comment Share on other sites More sharing options...
Irvy Posted September 14, 2004 Author Share Posted September 14, 2004 i hadnt thought of that...i will have to check with the local guy..he replaced them 5000 miles ago...if this helps i'll let you know but can say this...the grin on my face due to a big burble and big whistle...is definitely worth it:flame Dev Quote Link to comment Share on other sites More sharing options...
terribleturner Posted September 14, 2004 Share Posted September 14, 2004 Had my nur spec r on for just over 6 hours now and i keep finding excuses to go out and drive. Seeing the girlfriend in a moment, so yet another excuse to take my car out. Quote Link to comment Share on other sites More sharing options...
merckx Posted September 14, 2004 Share Posted September 14, 2004 I fitted my Nur Spec in May, took the cats out 2 weeks ago and its even louder! Superb in confined spaces with walls on either side!:flame Dev Quote Link to comment Share on other sites More sharing options...
