I bought a used TD06-20g kit, and need to buy some lighter springs. How can I differentiate the difference between all of the styles of wastegate?

Also, where can I find the Greddy wastegate to manifold gasket and the gasket that needs to be replaced when you change out the springs.

 

still trying to figure this out.

 

i think most of the greddy wastegates use the same style springs, you can measure the outlet to see what size the gate is..here is one place that sells partshttp://performance.yoparts.com/gredd...s/g-50278.aspx

 

i opened mine up and it had a yellow spring...

from research i THINK it's a .8-1.1 bar?

should be good for what I need it for I think.

 

Thats correct, it should be a 15psi(ish....greddy has odd ratings due to the adjustment on the gate) with the yellow spring.

Also, FWIW, the TD06 kit's I've raped from various cars have had 46(or 45, I wasn't using an uber accurate measuring device ) mm Type R gates on them.

 

ya i have yet to measure it... but its pretty big. i measure the flange that goes to the manifold or to the screamer pipe?

so the yellow spring as as light as you can possibly go with this gate? I want to run really low boost for the first little bit until the car is tuned properly.

 

why dont you just use a boost controller?

 

well you can't go lower than the wastegate setting....

if the spring is a 1bar spring, I can't run .5 bar... it doesn't work like that.
