Turbo/boost problems?

Mine looks like it's never been removed.

Is the wastegate actuator vehicle specific, or can I use the new (Subaru) one I have here?

They are turbo specific though it might work if you test it first to be boost not vacuum valve with similar power spring and the rod has the same "travel", if you apply pressure with a pump or compressor to it's port the rod must be pushed out the same as the original.... though i must insist that as long as you dont get overboost with clamped actuator pipe that valve would have no effect at all

At 350,000km, neither does mine. Be careful you don't get tunnel vision on this, Ian. You've been given some good pointers.

I'd suggest that nothing needs doing until we can see a log, there are many reasons for low boost.

Strangely enough the least likely causes of low boost are faulty turbo or actuator and WGM... But it could be one of those for sure.

The log will help isolate it without spending time and money loading the parts cannon.

Only a suggestion though.

I'll try to work out how to do a log, then check the wastegate is free. Then spend money, I don't have, as required.

Right, there's half a day just to format the SD card. How do I now record the data, then transfer it to here?

I'd take it for a spin with the air box cover off and filter removed and the cat converter down pipe removed as well.
Both of these were boost issues on mine (restrictive snorkle and clogged cat)

More fun than formatting an sd card

Start the engine, go to "inputs fuelling", click on the card icon bottom right, name it and follow the steps untill it starts recording, go for a ride, at the end save then downolad the data from SD card to laptop, convert to excel(or use CSV viewer) and attach the file to forum

I think the nanocom saves the file as a CSV, so no converting is needed, just upload it.

If you can't attach it here, PM me and I'll help upload it.
