I just put a s300 turbo or a 64/71/14 and I have no idea what it boost cause my gauge only goes to 30psi. I have water in the oil and pressure build up in radiator. HeAd gasket????

 

More than likely. Could also be a crack in head or block, or a leaking oil cooler.

 

mine done the same thing took my head off and had it re-built and checkt for cracks and they said it was good put it all back together and it still does it so ether the machine shop didnt check the head and its junk or my block is busted not sure i would like to find out for sure but i dont now were the blocks crack at most of the time does yours have much blow by maybe yours is just a head gaskit best of luck to ya

 

id put money on u lifted the head with ur turbo. u didnt mention head studs, so if u dont have them, then u need to be getting u some. also, u need to get ya a bigger boost gauge so u can adjust ur waste gate. good luck

 

boost should be st at 42 lbs from factory

 

you should get a look at the oil cooler.

 

make sure you deck your head when you have it off.

 

Alrite. I was leaning towards head or head gasket cause a week after I put that bigger turbo on it this happened. I'm as going to check oil cooler. Yeah I'm going to go back with head studs as well. Thanks. I'm just glad all of yall didnt say oh ya your block is just a boat anchor now.

 

If I'm gunna deck my head and put 60# springs can't I put bigger values as well?

 

Wheres a good place to order some head studs, gasket set and an oil cooler
