Wastegate spring


Dash Rendar

Recommended Posts

My car used to reach 1.4 bar with the EBC set to around 50% duty. But now it only hits 1.2 bar, regardless of how high I set the EBC. Ryan and Darryl are of the opinion the wastegate spring is at fault and needs replacing.

 

It's been like that for about a year or so, but I don't really mind running at 500bhp (which is what it dyno's at with 1.2 bar). But the car has a service coming up, and I thought this might be a good opportunity to put in a new spring.

 

Darryl wasn't sure if the springs are interchangeable between wastegates (mine is the XS Power), so he suggested I post up a thread here.

 

Can anyone tell me what I need, or a source?

 

Thanks.
