Damien_BAXR6T Member 31 Member For: 13y 8m 25d Posted 19/09/11 07:37 AM Share Posted 19/09/11 07:37 AM hey guyshaving some trouble with my BA XR6 Turbo 5spd manual.got the car for cheap as and found it doesnt make any boost...with a friend and lots of advice from people I work with we have:taken the Turbo off aswell as the Actuator and wastegate assembly and sent it to MTQ in Brisbane (where I am located).was returned saying it was fine.Put a different turbo-back stock system on from a mates car that we know isnt blocked and put a aftermarket cat back system on.all new piping cold and hot side and new intercooler.different plugs and coilsdifferent actuatortried different boost solenoid and even bypassed it (codes said there was a solenoid fault when looked at with IDS before any work was done)checked boost solenoid wiring for continuityBlocked off the BOV to make sure it wasnt leakingsent the ecu off for diagnosis but the company said they cant check on the boost side of the ECU (useless I know, if you know a company that can check the boost side of the ECU for faults that would be great as I cant find one)after all this my only thoughts of what it could possibly be is maybe the flapper cant close properly even if the actuator does work (but the assembly was sent to MTQ and cleared?) or that the ecu does not want the car to make boost and has a internal fault.with the IDS set up on a drive the car made just past atmospheric pressure but barely and at the first hint of boost the solenoid opens right up, disconnecting and bypassing the solenoid makes no difference. havent had a drive with the solenoid disconnected (and IDS hooked up) but it drives exactly the same. just completely stuck here...get off p-plates in 1 week so then I can drop it at RDP in brisbane to see if they can find out the problem on the dyno or computer and current getting our mastertech to look at it but if you guys have any idea's it would be great to hear from you.cheers for reading guys Link to comment Share on other sites More sharing options...

Double check your flapper can close/open freely. It wouldn't matter that the turbo has been cleared by MTQ, they wouldnt have had the dump pipe to check to see if the flapper can close properly, correct? 1 Link to comment Share on other sites More sharing options...
