Hey all i was fiddlin round with my car painting the cooler piping from disgusting yellow to heat proof satin black the other day and while it was all off i adjusted my wastegate nut in tighter so that while the car was off it was pulling the actuator in real tight but then took it for a drive and have no boost! So i tried adjusting the controller to little or no change. Then i put the actuator bolt back in its original position so it wasnt tight anymore and now i have EVEN LESS BOOST! WTF??? How can i diagnose if its a boost leak from the stupid o-ring (which i painted by the way) Or if i've damaged the actuator somehow from pulling it too tight? Cant seem to get any boost and the boost that i do get is sooooo slow to build!! What have i done!!!!?????

James,
Which way did you turn the actuator attachment?

Sounds like you've undone it rather than doing it up.

or a massive leak, if you pinted the o ring i cant imagine it would seal that well

Epic i must say.

No crap Terrance..........what you posted was already stated..............or are you in this just for the post count?

When i first did it i turned the attatchment towards the actuator/away from the turbo. So that i had to pull really hard on the rod to get it to slip over the thingo & put the circlip back in. but then i wound it back to its original (i think) position judging by where the thread wasnt rusted.

hmmm could be. I didnt know there was a o ring on it till i went to put it back in! Why do they use such a strange setup? The nissan turbos just use silicone joiner from the outlet to the cooler piping and they never have heat issues. Could i do the same with my tc06? (if thats what i actually have on there that is)

Make sure your outlet pipe from the turbo is bolted down to the bolt hole on the turbo its self or under boost it will move up leaking all the pressure

and you were right wind it back up to the actuactor to get the most out of the stock one its hard to put back on

Epic i must say.

If you adjust the actuator so that the hole in the arm is about half the width of the hole too short then this is roughly right for stock boost.

Disconnect the vacuum/boost line to the actuator and go for a drive, this will tell you if the turbo is making boost still.

Yep its bolted down to the turbo. And so if i make it so its hard to get back on im doing it right? I am aiming for 16psi is that achievable with the actuator on these in the stock position?

Tried that today and it didnt make a difference. Car was boosting fine before a messed with it so turbo should be ok.
Cheers for the help guys! I'll get it sorted if it kills me

If you have disconnected the wastegate vacuum line and the actuator adjustment is tight and you still are not getting much boost then there may be something wrong with your turbo. Take the inlet off and give the wheels and shaft a look and feel. The wastegate flap may be damaged too.

can i pressurize the system somehow to test the o ring? I doubt its the turbo as it was fine before i tampered with it all. I may have damaged the wastegate from pulling it too tight me thinks......

James,
As stated before remove the line to the wastegate, take the car for a drive........if you have boost issues the car will lack boost (obviously) ............but if it comes on strong and keeps going remove your right foot or look at the boost gauge, the standard one will go ALL the way to the top.................right until the boost (ignition) cut comes in.

Yer already did that and i have got boost issues coz it makes no difference. Also just thought i may add something of interest as when this started happening my standard boost gauge stopped working. It just slowly creeps to the top over the period of a 45 minute drive! No fluctuating just slowly but surely upwards! WTF???
Cheers Andrew.

U will need a boost controller and to cut the yellow wire if u want to obtain 16 psi also u will need to adjust your timing if you ping

With the actuator arm off can u move the wastegate arm?

Is it miss fireing at all? black/blue smoke even white? any bad noises?

Has the joiner the connects the cooler piper to the t/b been damaged or any joiner for that matter?

check recheck all your pipers and clamps and perhaps check for splits if its using the stock one they do crack and open up under boost and under vac close up again mostly any way

p.s.
Silly question did you play with the blow off valve at all i see you have one listed in your cars thread. these if tampered with are nice big boost leaks


also try using the edit feature to avoid post lots of replies might be easier for you.

Epic i must say.

Already have a Turbosmart boost controller and the yellow wire was cut before i bought it.


Yep it flaps around freely.


Yes it misfires on idle a bit and always seems to be puffing a very small amount of white smoke that looks like steam.
Smells rich too, But it has been doing all this since i got it and it was running 15psi fine then.


I would love to pressurize my system with my air compressor to check for leaks if anyone knows how? But i cant "visually" see any cracks (that doesnt mean they arent there though)



Yes i did actually, The BOV was wound all the way in tight and wouldnt work so i wound it out and now it works...... hmmm


How about what ive done above? ^^^^

Cheers for the great responses!
