Hi all, I have a S2 C34. The car has begun to surge when being driven up a steep hill, like the street into my home. It feels like the cars rev swing up then down then up and down again. On the flat road it is running fine, no weird noises, smoke etc. The car has a few mods but has been running fine up until this afternoon. As it is my wifes car and I have a small one in the back, I hope it isn't anything too major! Any thoughts? Fuel pump, Atessa? Thanks Rob

AI SP1200 Surge Tank and Holley Dominator Pump Hi Guys, I have for sale my AI SP1200 Surge Tank and Holley Dominator Pump. Was running this setup in my car for the last year or so during which time it's done maybe 3000km's total so not much at all. Was providing plenty of fuel for the 470awkw setup I had at the time whilst being next to silent (couldn't hear it inside the car). As the Holley Dominator is technically 2 pumps you can run them in a staged setup which is how I had it which keeps fuel temps down when you don't need a lot of fuel. All working perfectly when removed and comes mounted on a nice little plate ready to be installed. The only reason I have removed it is this system will cap out at around 650awkw or so and I need something a little larger for my new setup. Price is 1000 ONO. Item is located in Rouse Hill, NSW and pickup is preferred over post. Any questions contact me here on SMS/Call 0403858714. Thanks, Brett

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.
