RB25 Fuel and compressor surge issues. HI guys I just want to say how frustrated I am with my stupid car. I have sent this issue to 4 mechanics in gold coast and no one can seem to fix it. Basically the car feels like its compressor surging under light acceleration and feels like something is restricting the car power wise. The car wont pull like it should and feels more like a civic. The car also sounds raspier and harsher than it usually does. The back of my bumper is caked with oil and completely black. Looks like it might be over fueling or something. You would think it would be picked up on the dyno though. At times, although rare, it will free itself up and boost like it should but its a rare occurrence when this happens. when this is happening the car is is using a crap load of fuel. It would easily go through a whole tank of fuel in half a day. This isnt normal. I think lowering the boost and duty on the EBC seems to help slightly but im not sure. I have had the car on the dyno and no one can seem to find the issue. mods I have done Power FC front mount full exhaust spit fire coil pack aftermarket fuel pump AVCR boost controller stock turbo and injectors. I have done everything humanly possible to fix it. Boost leak test, replace waste gate actuator. All new piping. I don't know what else to do! any help would be greatly appreciated.

R33 intermittent loss of power. R33 intermittent loss of power. Hi guys. I have an R33 gtst series 1.5 List of mods Full high Flow xforce exhaust K&N pod filter whith heat shield Blitz front mount intercooler Spit fire coils New spark plugs ( unsure of brand) Power fc tuned by legend matt spry Z32 airflow meter Stock turbo running 13 pounds Car is making over 200kW at wheels I have several issues. There are days when my car feels nice and responsive and goes like a bat out of hell. And there are days when I feel like I've lost about 30 hp through my mid range top end power. At times my accelerator feels less responsive / sluggish and boost doesn't feel like it comes on hard. Also the car back fires and splutters at times and feels like the car is vibrating and shaking slightly when at idle..but not always. At times it feels like boost is flowing through a McDonald's straw. Now the other strange issue is sometimes when I stab the throttle to rev match the car will bog down but not always. It's very inconsistent. And my fuel economy is terrible. I have also noticed some oil leaking from intake manifold. I was advised it could be a sqaushed gasket causing boost leak? Only strange thing matt spry saw on the dyno was the 02 sensor was crapping out when the car is cold and dumping crap load of fuel but fixes itself when it warms up. Could it be piston or valve issue guys? Problem is extremely frustrating and has been happening since I've owned the car. I just want my pride and joy to be running 100% Any help would be appreciated guys.
