spackrackman Posted June 27, 2006 Share Posted June 27, 2006 Hopefully buying a rsr GTII exhaust and two decat pipes, have got myself a boost controller coming and an FDC. Does the stock manifold cope with extra boost etc? or should I be changing the whole exhaust system? anything else I am missing. Thanks in advance Quote Link to comment Share on other sites More sharing options...

Thanks in advance Hi mate Both Cats out, FCD, Restrictor ring if its a J-spec, and Colder plugs etc it helps if your intercooler is in good nick as well I would reccomeng an EGT and boost gauge as well hope this helps Quote Link to comment Share on other sites More sharing options...
Alex Posted June 27, 2006 Share Posted June 27, 2006 You can't change the stock manifold...there is NO alternative unless you change the turbos too bor say a single. EDIT - You're UK Spec IGNORE THIS PARAGRAPH - J-spec readers this applies to you. You may find you're overboosting with a double decat, if you don't have a restrictor ring. If you don't have a restrictor ring speak to Chris Wilson and get one off him to limit your boost to 1.1bar....you can use a boost controller to up it above that. 1.25bar is a Quote Link to comment Share on other sites More sharing options...
spackrackman Posted June 27, 2006 Author Share Posted June 27, 2006 Ok, let me get this straight.. firstly whats an EGT? so as I have a UK car do I need to get a restrictor ring fitted? can't I control it via the boost controller? or as I understand the restrictor ring sets a level and then I can use the boost contoller to push over that? I sound confused but I am getting there.. and what plugs are best? as i can buy them today with my exhuast. Should I do my fuel pump while I am doing this? basic BPU?

Alex Posted June 27, 2006 Share Posted June 27, 2006 EGT = Exhaust Gas Temp. Your UK car should only boost to about 0.9bar with a full decat, you'll need a boost controller to raise it further. You don't need a restrictor ring as your wastegate isn't over run like the j-spec version. BKR7E plugs gapped to 0.7-0.8mm (make sure they are the same which ever you pick) and change them every other oil change. Your fuel pump should be ok for BPU...but if you're concerned buy a GSS341/2 from one of the traders. Quote Link to comment Share on other sites More sharing options...

What exactly does that mean? wastegate is over run? and this EGT, if I got a sensor maybe my boost controller will monitor it? ermmm...

Thanks by the way Alex "ISN'T" not IS sorry my typo. When the wastegate that controls the boost on a turbo is too small it gets overrun and fails to control/limit boost...the j-spec turbo's suffer this, the UK spec turbo's don't. You use a boost gauge to monitor it UK spec's don't need restrictor rings/plates as your turbo's are better than the j-spec ones. Quote Link to comment Share on other sites More sharing options...
