Stuck wastegate.

[Lee]

I was wanting to put a few more pounds of boost into my EVO III (want to run 15psi) But i found that no matter how much i turned the boost controller, it didn't raise OR Lower boost.
I got under the car and i found that the wastegate was stuck 1/4 open.
Any idea's to get the wastegate flap moving freely?
I have tryied vice grips but i could only moved it more open & not closed.
Has anyone had this problem?
Thanks in advance.
Lee.

Hey lee, is the flapper stuck or is it the acuator. If its the acuator I think dane might have a spare.

 

[Lee]

Dont realy know as yet, but it appears that the flapper gate seems to be very tight.
I might have to wait till the car is cool & take the split pin out & see if it is the flapper & if i can move it.
Cheers.

Yup! Come down to Dane and Daves dodgy deals and rare spares :lol:

Hopefully you will get it sorted.

 

[Lee]

Hahaha.
I'll let you know if i need one mate, Cheers for that.

Ok it's the wastegate acuator that is stuffed, It moves back (To lower boost) But doesn't move all the way back into the closed position.

Dane i might need your spare if ok?

Just a few Q's
Are the GSR 4G93 acuator's the same as the EVO 3 4G63 in shape, bolts lining up & the rod length & Spring tension?

 

[Lee]

NOW FIXED

2 words............... HOLLY CRAP!!!!
This should be into the 12's now. Cant wait till the V8 vs WRX meeting!!

I never seen boost responce like this B4, I had a bent/caved in acuator (The main round bit that holds the spring) now it springs upto 15pound in less than a second.

BIG thanks to Dane. :wink:
