ok so heres my problem i have a 95 gst and at idle or while driving under 3k rshared_pm it wont over heat. but when i get on it and get into boost thats when it goes straight to red and coolant pours out the overflow. it got so hot it melted one of my fan blades. i put a new turbo on a few months ago e316g and it never did it b4 the new turbo has anyone had this problem? it doesnt smoke or anything so i hope its not a headgasket

 

clearly a blown head gasket

 

Yep.

 

damn well how do i prevent that form happening again or do thoes just blow for no reason

 

what brand and thickness head gasket do u guys recomend

 

What are tuning with and are you monitoring knock? what fuel upgrades do you have to the fuel system? how much boost were you running at the time??

there are many reasons why a head gasket can blow, we need more info on your car before we can make an assessment.
Sometimes just the head gasket being old can cause it to blow.

 

safc, rc 550,aeromotive afpr,walbro 255,evo3 16g, apexi tbe,i was at 15 psi , but what i dont get is there is no smoke and there is no milky oil, is everyone sure this sounds like a blown head gasket, only guages i have is oil pressure aem wide band and boost

 

its a blown headgasket.. have had a couple and didnt have any coolant going into my oil.. But anytime the car saw boost it would overheat..

 

anyone have a recomendation for brand and thickness i am having it dyno tuned at 20psi and im not sure if oem can handle that continusly,thanks guys for the bad news

 

your setup sounds pretty mild, it could have just been a old head gasket. when my head gasket blew I did not have any smoke out the exhaust either.
Are you going to be replacing the head gasket yourself?? I have always used felpro gasket with ARP studs. I like the idea of a $30 head gasket going out instead of a rod out the motor if something were to go wrong.
