The other day was on boost then suddenly lost all, black smoke galore.

I've checked all the hoses for leaks, they seem ok.

Turbo still spools but not as quickly.

I have a Turbosmart boost-t with the gate still in, wound all the way down.

It sounded like the gate stuck, then suddenly let go, surging the shit out of the actuator.

Is it possible this surge damaged the diaphram ?

yeah I'll start by changing all the vac line with silicone tube and hose clamps.

found a small split, cut it back but still losing boost somewhere.

I do have a compressor, how do you block off the intake to pressure test ?

Where's the best place to connect compressor.

Had the same problem the other day.

Put my boost leak tester here:

Had a boost leak on my SR 1600 and was a real high pitched squeal but with the stag not so much.

I ended up using my hand to feel for air and eventually found it when I took the front bumper off.

Ended up being the intercooler intake pipe hose clamp.

Yeah all the way anti-clock, means it opens at 3psi.

I just read somewhere you're supposed to wind 3 clicks off the bottom.

I had it wound all down, maybe causing the ball to catch in the boost-t.

Seems better now, But I'm pretty sure the vac lines are leaking.

You can pull them off easily without pressing the clamps.

Got some silicone hose and worm drive clamps coming.

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
