NO BOOST. HELP!!!
Hi all.. I have have a v3 Impreza Sti..alcatek ecu(with anti lag) full
Pipe..upgraded intake hose. Manual boost controller(which I'm taking our but came in the car) turbo smart dv
But it has no boost. It had a lumpy idle hunting up and down which I've sorted. Idle control valve. But no boost at all. Can runs fine with no misfires or smoke..
I've checked vac hoses, ran new vac lines(standard setup) without boost controller.tried it without the dv.. The restrictor pill is in the correct place(between t piece and compressor housing nipple) but I ran a new vac line from actuator to turbo housing to bypass the solenoid. And didn't get actuated boost. But I was told the solenoid should continue clicking when ignition is on and green connectors together.test mode. But mine clicks once,I've tried another which works on another car and that clicks twice on my car.. Although the I'm told the diagnostic mode may not be supported because of the map.? So may not continue to click? I also can move the actuator arm my hand,is pressure there. I'm stuck to what this could be. Any suggestions would be great.. Thanks

When I replaced the intake pipe as it was split I used a long screwdriver and carefully turned the wheel inside to check. So guessing it's not seized unless something else can seize?

You think actuator is knackered? I've searched for stock ones only thing that comes up for the vf23 turbo is kinuwaga(however it's spelt) actuators

I've disconnected the actuator arm and cable tied the wastegate shut.tempory just to try see if it builds boost. Which it didn't. I tied it shut,but guessing the wastgate is shutting properly. The actuator does need both hands to move the rod(open flap)

I've checked for leaks on every hose possible I think.. Guess taking the turbo off is the next step.. Fuel starvation wouldnt cause this would it? Although the car runs fine with no splutters etc.
