Hi peeps need some help, I have a 1990's UK 200sx S13 running a completly standard CA18DET but with a 3" Decat back exhaust. Now I know that adding any form of air flow modification is going to give you some form of overboost fuel cut which I have had and noticed especially when cold. but then then soon turned into a cold whistle when boosting now I dont usually boost my car hard when cold but I needed to heir it a few times and it was only present when cold. At first I was thinking maybe it could be a small boost leak from one of the turbo gaskets as they have probably never been replaced before. Now my boost has gone worse! my car used to pull like a train and spit flames and pop like mad. But now when I hit between 4000-6000 revs my boost dies and It makes a spluttering noise a bit like a fuel cut but not a harsh snap it just stops boosting/pulling and I have to change gear. what are my options to diagnose this and order the right parts? either Gaskets? inlet pipework/intercooler, ECU, Spark Plugs, Coil packs, or has my turbo gone? not noticed any smoke although maybe I'm being paranoid but my car smells rich and sweet like oily sweet but like I say no smoke I dont think. All I need to know is if someone has had simular problems and can give me some pointers as to where I should look first or common symptoms of parts failier. This car is my daily so it needs sorting for that reason as well as wanting to get some track practice in ASAP. Cheers please help me!
