car problems...need opinions
so i got this 95 mustang. turbocharged about 2 weeks ago. car seemed fine except it would start running hot if you drove it too long and i was told it needed a good rsadiator and fan instead of the stock rad and fan. so i put a new aluminum rad and 2800 cfm fans. here is what happens...car won't get hot if i baby it and don't get into boost. it has a t-60 turbo, stock heads, e-cam. so when i changed the radiator and fan i took it for a test drive. getting the turbo spooled up and beating it a bit to see if it could take it. well it got too hot again. the radiator and fan set-up should be able to handle cooling this engine without much problems. it is also putting a significant amount of white smoke out of the tailpipes. i'm thinking it has a blown headgasket. why wouldn't it be overheating until you let it get into boost though? alos i noticed what i think is too much bubbling in the radiator with the cap off. the oil looks good though...not milky at all and very clean. the antifreeze doesn't look like there is any oil in it either. its just weird to me that it runs pretty cool until i tach it out a bit and let the turbo spool up.
