I'll be replacing it with another wastegate, but i need some quick fix for right now.. so what type of glue can be used??

suggestions??

--------------------!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

UPDATE: Rubber cement only helped with dirt removal.so i went w/ high temp rtv silicone gasket maker. and reinstalled everything after 24 hours.. looks like this stuff works.

your avatar doesn't suck but your WG idea does. I'm all for rigging stuff if needed but this is one thing you don't want to mcguyver together IMO

 

i would use a tire patch kit

 

lol you guys are funny

 

it can't get worse than already is.. this is my second diaphragm.. so i'll be replacing entire wastegate.. worst thing that will hapen it won't work... i got overboost protection via ebc

 

rubber cement?

 

The wastegate diaphram is the rubber piece separating the side vacuum port from the top vacuum port right?

If so, I think if it were ripped the wastegate wouldn't hold boost correctly. I mean, it wouldn't overboost...

If that's the case, it's not going to kill you to drive your car. So, I would try to fix it with some crazy glue or a tire repair kit and hope it works. At least if it leaks you won't overboost (if I'm thinking correctly about the function of the diaphram)...

no.. it goes the other way.. a leak/rip in diaphragm will overboost.. as in my case

 

how bout **** NO

if you really wanna ghetto rig it... a tire patching kit is your best bet

Oh, well then, I wouldn't risk it!

&lt;--- still need to figure out how wastegates work mechanically, I even took mine apart one time to see if I could understand it better...

 

trying rubber cement.. doubt it will work.. car still drives as long as you watch wot, my ebc has overboost feature, so that helps prevent trouble.. but its unstable.. same setting can have different boost levels

this is tial 35mm.. i don't know if ill get another tial product.. the only turbo part i had problems with.

 

funny thing this has happened to me... purchased a tial wg and whoever pieced it together must have ripped a tiny cut in the diaphragm. i used some silicone glue and let it dry over nite. holding boost just fine, but it is risky...

 

haha.. so silicon glue heh... i'm trying rubber cement right now, doubt it will hold.. i guess i'll find out soon

 

ehhhh i wouldn't try just a quick fix man. i actually had this exact same problem with my greddy kit on my 93 coupe....

the kit that i had recieved used, the turbo was basically junk on it and the rod had snapped, so i just tossed it BUT kept the wastegate actuator arm. with the new turbo i got (used also, but still no shaft play), it didn't come with an arm, so i just used the one from my old turbo. well come to find out, the reason the first turbo took a **** in the first place, was that the diaphram inside the actuator had a slight tear/rip in it. so my neighbor who is an automotive tech and knows his **** about stuff, decided to give the good ol' tire repair kit a try. well, turns out this aparently wasn't the best of ideas, as it didn't hold and basically tore instantly again and well, the newer turbo needless to say took a **** on me also and was complete junk when the arm wouldn't open and close properly due to the janky diaphram i thought i would get away with

if i were you, i would look at a couple places like ATPturbo.com, Phoenixturbo.com, CheapTurbo.com to see if you can purchase a whole new actuator arm instead of trying to fix just the diaphram. i'm still kicking myself for not doing this the first time..... Hope that helped ya a little

Word, it worked! I tuned this f00s car like this and it held boost perfectly

 

Overboost protection on an EBC doesn't work without a functioning wastegate. How do you think the boost is limited/reduced?

 

why would you even want to chance something like blowing your **** up?

i don't think it has anything to do with wastegate being open, closed, or having a ripped diaphragm.. you set the level where overboost protection should kick in, decide how much to pull back (and that i'm guessing is opening vaccum port??) - i'm not 100% sure how it works, but it does

boost cut can retard timing, cut fuel, etc... therefore combustion cant take place

By dropping the timing and cutting fuel at the same time. Why would you think there is something called a fuel cut defencer or boost cut controller for factory turbo cars?

 

no.. not hondata boost cut.. i'm talking about blitz ebc.. when i had vacuum port loose onto wastegate, it overboosted really quick and that feature didn't react fast enough.. but with diaphragm ripped, it did something to pull back once boost reached the set level.

 

UPDATE: Rubber cement only helped with dirt removal. just finished applying high temp rtv silicone gasket maker. gotta let it dry for 24 hours before reintalling. tial wastegate needs stronger material for diaphragm, anyobody having overboost problems or simply higher boost levels than before, double check your diaphragm

hey, thanks again for advice.. silicon glue worked out good!!! i let it sit for at least 24 hours, applied on both sides of the tear.. and sanded the rough surface with spin sand-brush or whatever you call it.. i think thats what caused it in the first place.

 

What type of wastegate do you have that has already ripped twice?
