BigMoistyturbo Posted May 12, 2004 Share Posted May 12, 2004 I'm worried because my j-spec is boosting to 1.3/1.4 bar. All it has it apexi air filter,FCD,Cat back nur spec,HKS SSQ. What could be causing this? Before I reach the top of the rev range I'm at 1.4 bar and the car struggles to make the top of the revs! I still have both my cats in.

BigMoistyturbo Posted May 12, 2004 Author Share Posted May 12, 2004 I was thinking of buying the restrictor ring, and it's going in for a service this week so plugs etc will be changed. Is it normal to overboost with cats in? Link to comment Share on other sites More sharing options...
Guest Terry S Posted May 12, 2004 Share Posted May 12, 2004 Moisty, you want to bung in a colder plug like a 7 with more than stock boost. If you can't stretch to Denso IK's then get a set of BKR7ES from Halfrauds. Link to comment Share on other sites More sharing options...

Well, by that I mean to the extent you are seeing, as its possible with cats and an aftermarket cat back system to just creep above the stock fuel/boost cut in certain circumstances. Not as high as you've been boosting though......... Link to comment Share on other sites More sharing options...
Grazer Posted May 12, 2004 Share Posted May 12, 2004 Before I put in a CW restrictor ring I was hitting 1.5bar and AFAIK both my cats are still in Restrictor ring sorted it right out - now sits at 1.1bar Link to comment Share on other sites More sharing options...
