Hello there. 

I need some help. I have a ba xr6 turbo with some mods done. I have the turbosmart wastegate. Now my mechanic has told me that my car is overboosting. The wastegate is starting to open when im at 20psi. Which he tells me this can cause major problems. 

Why could this be and how can it be fixed?

What mods? 20psi is wayyyyyyyyyyy too much for a stock BA XR6T.

Injectors

air intake 

flash tune

valve springs

fuel pump

exhaust

nothalane diff bushes

 

mechanic is taking waste gate off atm to adjust boost level... 

My mechanical knowledge isnt that great with these types of things. Just want to boost changed and lowered so its safe.

Do not drive it on boost if its boosting 20psi. Is it the turbosmart internal wastegate or external?

[Kiwi1989]

Pretty sure its internal. Sits off the turbo. 

Can you adjust the boost levels through the wastegate?

 

 

And how is it fixed fo get it back under control?

[OZYWALKER]

Adjust the preload. If that doesn't drop it enough change the spring to a lower rated one.

Chances are it's a 12psi unit which has a 5 and 7 psi spring in it.

Ok thank you. 

Whats the pre load? 

And how do you adjust it?

 

thanks

[OZYWALKER]

Leave it for your mechanic.

[Kiwi1989]
