Ok so yesterday i cut back my Blow off valve dump tube in the stock airtake
and then took my car out for a drive, started boosting for about 5 seconds and my car starts to sound like a damn Kazoo... car still seems to be boosting ok (cant be sure stock boost gage) and is still quick. One thing i noticed though is i no longer hear the Pssshtt sound...
any idea's?
Is my turbo dead? is my blow off valve dead? Am i?

oh, the sound only happens under boost.
99 mitsubishi gst
107k miles
everything is still stock


I also just replaced the the pcv valve at the same time, but i doubt that has to do with anything
help!

 

Probably just the BOV. Never heard of it making that noise before, but from what you described it doesnt seem like it would be the turbo. But let me get this straight as to what you did to the dump tube. It is no longer running to the intake but just plugged off?

 

No, its still running to the intake just Cut it down so it wouldnt be restricting airflow going into turbo...

but anyway I think it is my turbo.... just took a picture

Maybe a piece of plastic broke off and went into the blade...
what do u guys think?
And can i fix this?

 

nope... the stock turbo is junk anyway... so its not worth anything to fix it.

I think a small stone or something got in there becaue plastic wouldnt do that.

Well as i always say... breakage is just an excuse for upgrade!

 

That sucks bro. Ya these T25's are crappy turbos anyway. Plus it'd cost you almost as much to get a new stock turbo as it would to get a bigger turbo. I hear the stock turbos on teh 1st gens are much better turbos. (though ask around to make sure my info is correct)

 

Yea your right poot but still they are along the same lines and you need to make a couple mods for the install.

 

actually the t 25 doesnt suck if u know how to drive and not run to high of a boost then u can run 13's with a "****ty stock turbo" ha thas what im doin ..and it runs perfect ...but if its broke then u might upgrade..i know a web site were u can upgrade to a bigger and better turbo that will bolt on derectly to ur stock manifold...

 

so do 100s of members

 

Give the guy a break, he's just trying to help and he's a newb so may not know what the extent of knowledge is here.[sm=icon_cheers.gif]

 

Ouch! that sucks. Well that turbo is basically junk now. No use in even trying to repair it. For the amount you would spend repairing you could just get a new one. There are plenty of things you could do to replace that one. Just buy a new T-25 or there are alot of turbos that use the stock mani. Some modification might be needed to get them to work correcty but its all up to how much money you got.
