hi can anyone help me please! went to drive my car back from my army camp and it had been working fine in the morning. obviously i let it warm up before i give it any kind of boost, at least 1/4 up the temp guage. the car was warm and i put my foot down. there was hardly any power with the boost going to 0 wich is vaccum pressuer i believe. theres a strange whining noise aswell.
ive had the turbo off and its all fine, there was however a little oil in the induction pipe but not much. ive checked all the vaccum and boost hoses and they seem fine. in a nutshell im running a motec m4 pro ecu with 1.1bar boost, 3inch exhaust from the turbo with 2.5inch restrictor so its not overboosting and a few other bits but theyv all been on for at least 6 months with no problems. so all i can think of is maybe the actuator or a sensor or something. can anyone shed any light or give me any contacts please thanks This post has been edited by pikey: Mar 18, 2009 - 8:09 AM |

sounds like what happened to my gt-four. the turbo shaft in my ct20b had excess play and the blades rubbed against the housing... expensive turbo rebuild... however for u since u have an aftermarket ecu u can go straight for a brand new garett instead of a reconditioned toyota turbo. wish i had the same option because the cost would have been the same.

QUOTE (Cuts_the_Pilot @ Mar 18, 2009 - 3:15 PM) what dump pipe you using? some have been known to jam the wastegate open, which gives the same result. not even a year old blitz ssq but will tell the garage to have a look as its an option |
