Mr Typhoon 500kw Member 7 Member For: 15y 8m 27d Gender: Male Location: Sydney Posted 07/04/09 12:11 PM Share Posted 07/04/09 12:11 PM hi all, I am just building a 500kw ATW motor and have a new exhaust manifold , when we installed it on the bench the bloody thing looks so high the turbo housing is above the oil filler cap (4.0L Barra motor)any ideas. I hear that the GCG manifold (which I have)was discountinued due to uncontrollable boost because the runners were an irregular length and caused issues.?

The internals are Je Forged and I beam rods, Exhaust manifold is GCG with 60mm external gate along with To4Z turbo. Valve springs upgraded. Standard box but 3000+ Clamping pressure single plate clutch with 10 puck plate...The fuel system surge tank is process west with 044 pump and will be upgraded to have 2 x 044 pumps. with 75lb injectors.Look at the height of the sucker in the photo, note it is not flush with the flange but bloody high.!!!Alos any recommendations for tuner.?? MRC Performance tuned the car to 400.5kw at the wheels prior but it leaned out and cracked piston 4 !!! 15k later see attached photo.!I have spoken to C& V also Autotech and BTA. I think this setup will make 500+ on race fuel. Edited 09/04/09 05:37 AM by Mr Typhoon 500kw Link to comment Share on other sites More sharing options...
