str8 6 turbo Member 7 Member For: 13y 10m 26d Posted 11/02/11 08:33 PM Share Posted 11/02/11 08:33 PM Gdae, I've recently brought a 2003 ba xr6 turbo falcon, its done 100,000kms now. now my problem is a lack of boost when at operating temperature, obviously over-fueling is a consequence. Any wanted response from the turbo after 2500 - 3000 rpm results in that over-fueling. I've cleaned and checked all the intake pipes, also replacing all the factory hose clips with the hex head variety. The wierdest part about this happening is that I get full reliable power and full boost before the engine has come up to temperature, power then fades as operating temp is achieved. ive owned a few straight six turbo engines (the nissan RB skyline series) and also have rebuilt them plenty of times with no hassle, but this BA has completly stumped. are the turbo seals gone? or perhaps an ignition problem, hopefully just a sensor (boost solenoid) but either way I'm at a loss, so if anyone knows or has had this problem before could I please get a solution to my irritating problem?
