1G Billet adjustable wastegate.

Anyone run one? My wastegate is showing its age. Maybe its time

My car is 100% stock. '91 GST. Doesn't boost til 4k

New diaphragm isnt likely to help. Find the root cause

 

[pauleyman]

That isnt actually the wastegate, its just the actuator

 

[Freddyk79]

Oh OK. Thanks for the insight. Gonna have to take er apart and see what's going on then

I have one but not running it yet, will be on next year, what one you looking at

 

[Freddyk79]

Not sure yet. All I know is that my car doesn't seem to boost until 3500+ rpms. Bone stock. Took a look at the manifold yesterday and didn't see any obvious cracks

 

[FIBA M - EC17PSE]

Have you done a boost leak test!

It's probably a misaligned flapper and/or extreme cracks in the housing...changing the actuator isn't going to help you at all.
